- "Upon my honor I do swear undying loyalty to the Emperor… and unwavering obedience to the officers of his great Empire. May those above judge me, and those below take me, if I fail in my duty. Long live the Emperor! Long live the Empire!" —Imperial Legion oath
The Imperial Legion, also known as the Red Legion, Imperial Army and the Ruby Ranks, is the main fighting force of the Empire of Tamriel. It is often pluralized as the Imperial Legions. It operates under the auspices and authority of the Emperor himself. With its vast numbers, quality training, and rigid discipline, the Legion is considered one of the best armies ever assembled in history. The primary mission of the Imperial Legion is to preserve the peace and rule of law in the Empire. Those who protect the Emperor and the Imperial Province are sometimes called the Imperial Guard and the Imperial Watch. A Legion Centurion is typically in command of the Palace Guard of the White Gold Tower. The Tribunal God Vivec referred to the Legion as moths.
In peacetime, the Legion serves primarily as a garrison force — manning forts, patrolling roads, and providing guardsmen for towns, cities, counties, and nobles. They are empowered to arrest criminals and seize their property, among other things. In wartime, the Legion's responsibilities and powers are greatly increased. During conflicts, the Legion serves as an invading and occupying force, overwhelming opposition with numerical superiority and strict economy of force. The aquatic equivalent of the Imperial Legion is the Imperial Navy, with the two often overlapping.
The Legion is divided into structured and disciplined military units; the primary, and largest, of which is the Legion, which is further divided into Cohorts. Legions are numbered for identification, and each possesses a proud history and sub-culture. Of note, for example, is the 10th Legion, which was destroyed in the Imperial invasion of Akavir. The Imperial Battlemages are a rich tradition of war mages trained in the support of the Legions. All facets of warfare are accounted for in Legionary operations, and the Legion employs large numbers of highly-specialized troops in conjunction with one another to achieve victory, among them archers, light and heavy cavalry, battlemages, and healers. Imperial Battlemages are often mixed with other legions, but also form cohorts under a Battlemage Palatine, who acts as the commander of the cohort. Imperial organizations, such as the Imperial Society, requisition legionnaire support as needed for their endeavors. A special Legion platoon comprises the guard of any Duke in the province of Morrowind, the Duke of Vvardenfell, for instance. These soldiers are among the best the Legion has to offer; the most accomplished soldiers of the Duke's guard have the honor of serving as personal Palace guard to the King of Morrowind. The Legion was also known to have an expeditionary force, that was known to have put down tribal uprisings in Black Marsh.
Tying into the Legion's versatility is its non-discriminatory policy of recruitment. The Legion recruits individuals of all races and creeds into its ranks and benefits from the diversity of skills they all bring (although men form the vast majority). The Legion's strict standards of recruitment choose candidates for service on the bases of endurance, soldierly virtue, and trustworthiness, among others. Orcs earned citizenship by service in the legions, and have come to be prized by the Imperial Legion for their skills in smithing and heavy armor. The Legion is one of the very few groups to treat the Orcs well. Kothringi were known to be a large part of the Imperial garrison of Gideon. Lyris Titanborn, a half-giant, was a member of the Imperial Legion, rising quickly through the ranks due to her strength and height. The Legion has also had multiple Dragons serve underneath it, such as Nahfahlaar, who served under Tiber Septim, and Dragonne Papré.
Service in the Legion is considered a model of Imperial citizenship, and as such requires a high standard of excellence. Influential Imperial military families would often send their children to be trained in legionary academies, such as the Topal Legionary Academy, where they would be trained to be elite soldiers. Legionnaires are typically expected to be at the peak of physical fitness in order to weather the rigors of melee combat and long marches in heavy equipment, demonstrate mastery of blades, polearms, and blunt weaponry, and have great skill in utilizing heavy armor as well as hand-shields.
The Alessian LegionsEdit
The first incarnation of the Imperial Legion arose under the Alessian Empire in the First Era, when it was known as the Alessian Legion. Legends speak of the legions led by Morihaus when the man-bull took the White Gold Tower. The Legion sprang from the hardy rugged stock of Colovia and the sophisticated battlemages of Nibenay. United, the warriors of Cyrodiil were a force to be reckoned with.
The Alessian army spent most of the third century of the First Era securing Alessian control over Cyrodiil, slowly overcoming Ayleid holdouts despite their magical prowess and often ingenious tactics. The Alessians fought many Wars throughout the First Era; many cultures have legends speaking of the seemingly unstoppable legions of Empress Hestra circa 1E 1030. Nevertheless, the Legion's fortunes have always waxed and waned along with the Empire. When the leadership of the Alessian Order succumbed to internal squabbling, the War of Righteousness began, a decade-long civil war which no doubt pitted legionnaire against legionnaire.
A New LegionEdit
Once the province was reunited again under the god-hero Reman I circa 1E 2703, his legions spent the last two centuries of the First Era reestablishing an Empire of Man in Tamriel. The Imperial Legion as it is known in modern times first appeared under the Second Empire, thanks to the influence of the Akaviri Dragonguard. Their weaponry, methods, and rigid discipline turned the Imperial Legion into the unparalleled fighting force which was able to conquer every region of mainland Tamriel (save for Morrowind). By the end of the era, the Summerset Isle was the only modern-day province which had no Legion presence. A known member of a Reman era Legion was Luciana Pullo, a battlemage and lieutenant during the Akavari troubles and Valenwood annexation.
Under the Akaviri Potentates at the beginning of the Second Era, the Imperial Legion achieved something unthinkable: they became the only fighting force in the Empire. In 2E 283, when faced with widespread rebellion, Potentate Versidue-Shaie declared martial law, demanding that all of his vassals dissolve their armies. After thirty-seven years and enormous sacrifice, the Imperial Legion had quelled all who did not obey, wiping out any organized resistance to them within the Empire. They were the only army in the land.
Puppets of PretendersEdit
During the Interregnum of the Second Era, after the dissolution of the Second Empire, the Imperial Legion became the instrument of various warlords in Cyrodiil, notably the infamous Tharn family. Many disparaged the Legion around Tamriel during this time, claiming that it no longer exemplified the superb qualities it had in the past. At the beginning of the Planemeld, all Legions were recalled to the Imperial City,, but many couldn't make it to City Isle and instead set up isolated camps throughout the Heartlands as the Alliance War raged around them. Legionnaires who were in the Imperial City when the Anchors began to drop were given the option to swear fealty to Molag Bal by drinking the "Blood of Coldharbour", a poison that would slowly turn the imbibers into Mind-Shriven. Many instead chose death, but those who turned traitor formed a new regiment called Legion Zero. Legion Zero cooperated with the Xivkyn occupiers, and transformed the Elven Gardens District into a workshop for constructing siege equipment for the Daedric forces.
A group of loyalist legion soldiers led by Captain Anatolius Caudex, known as the Immortal Eight, created an improvised garrison in the middle of the Nobles District in the Imperial City, where they fought against the forces of Molag Bal and against Legion Zero. They also played a part in stopping Bal's plans to snuff out the Dragonfires. Captain Caudex had previously defended Fort Warden from the three Alliances, being the last man to leave the fort, stating that the "Rebels must learn that the Empire is invincible. So we must be invincible."
Elsewhere in Tamriel, Legion troops under the command of the Tharns became engaged in relatively minor campaigns to annex surrounding regions, with little long-term success. Circa 2E 582, Colovian troops under Javad Tharn entered Aldmeri Dominion territory in a failed attempt to annex the Reaper's March region south of Colovia. Under Magus-General Septima Tharn, the Seventh Legion became engaged in operations across much of Tamriel, often with very little support. An example of this was when the Seventh Legion entered Daggerfall Covenant territory in a failed attempt to annex Bangkorai. The Legion's leadership was encouraged to act ruthlessly, and they often engaged in abductions, as well as summary executions of disloyal soldiers, disobedient prisoners, or recalcitrant conquered civilians.
The Tiber WarsEdit
In 2E 852, the Tiber Wars began, and nothing would ever be the same. In the dead of winter, General Talos led a small army from Cyrodiil to take the mighty fortress of Sancre Tor from the allied Nord-Breton forces which had occupied it. The Cyrodilic army was small, poorly trained and outfitted, short on rations and unprepared for winter campaigning. And yet, the man who would become known as Tiber Septim led them to victory.
The Battle of Sancre Tor was just the beginning of a renaissance for the Imperial Legion. Young men in Skyrim began to flock to Septim's armies. With his invincible General Talos, King Cuhlecain was able to unite the Colovian Estates in a year, and soon thereafter in 2E 854 took the Imperial City, taking the title of Emperor. He was soon killed, and Emperor Tiber Septim took his place. His ever-loyal soldiers solidified his hold on Cyrodiil and High Rock, and then targeted Elsweyr.
The Legion suffered its share of tribulations while forging the Empire of Tamriel. In the Battle of Black Rocks in 2E 863, the Aldmeri Dominion almost destroyed the Third Legion and the initially smooth annexation of Hammerfell the following year was disrupted by the Stros M'Kai Uprising. For a brief time during the Moth Rebellion, Tiber Septim was driven out of the Imperial City and the Legion within the city was besieged. And Tiber's generals positively dreaded a campaign against the Dunmer of Morrowind (though they were spared from attempting to conquer the entire province thanks to the Armistice).
One by one, the provinces were brought into the fold. The Summerset Isle had never been successfully invaded by the Legion, though they were reportedly more than capable of repulsing elven incursions. But finally, in 2E 896, Septim's use of the Numidium brought the homeland of the Altmer under his control, making him the first true Emperor of Tamriel.
The Third EmpireEdit
Under the Septim Empire, the Imperial Legion regained its reputation as a model military force. From Morrowind to the Summerset Isles, the Legion helped keep the peace. It had to manage a great deal of insurrection, the many major wars of the Third Era, and piracy, not to mention the disastrous invasion of Akavir circa 3E 288. They developed and maintained a system of garrisons throughout Tamriel, manning and supplying each in accordance with the threats they faced (though some questioned the significance of these threats given the exorbitant cost of maintaining this system). During this time, they were known for their close association with the Imperial Cult, which frequently provided services in their forts. The Legion maintained a strong presence in Morrowind throughout the Third Era, and it is believed that Dagoth Ur, before his defeat at the hands of the Nerevarine, was preparing for an extended campaign against them utilizing assassination and terror.
The Imperial Legion had a great presence in Vvardenfell under the Septim Empire, with there being many forts dotted around the island; Fort Darius, Buckmoth Legion Fort, Moonmoth Legion Fort, and Fort Pelagiad were main strategic locations. Pelagiad itself was founded by Legion veterans that had retired.
In Gnisis, the Deathshead Legion helped secure the Gnisis Kwama egg mine, as the queen had been blighted, eventually, the legion cured the queen of the Blight, allowing work to continue in the local area. Certain members of the Deathshead Legion were involved in a conspiracy involving the Talos Cult, planning to assassinate Uriel Septim VII and replace him with a stronger ruler. This conspiracy was put down by General Darius.
The Hawkmoth Legion was mostly involved in matters involving the Ordinators and Buoyant Armigers. With the legion being accused of having no courtesy by the Armigers, and with an Ordinator spreading lies about the legion. The legion resolved the strained relationship with the Armigers by beating one of their members in a contest of wit, poetry, and honor. The Ordinator that had been spreading lies was slain by the legion. The Ordinators also attempted to kill an Imperial Knight that had been accused of murder, this attempt on his life was stopped by the legion so that he could get a fair trial in the mainland instead.
The Buckmoth Legion prevented illegal trading of Dwemer artifacts due to all Dwemer artifacts being considered as the Emperor's property. It also saved a knight of the Order of Ebonheart and assisted the Armigers in preventing a scandal involving an affair.
The Moonmoth Legion assisted the Nerevarine by giving them supplies due to the influence of the Grand Spymaster of the Blades, Caius Cosades. Larrius Varro, a Legion Champion, was also present at Moonmoth, with him tasking a legionnaire to kill a Nord who had been robbing travelers near Hla Oad. Varro also tasked the Nerevarine with killing five members of the Camonna Tong in Balmora, as the local magistrate was corrupt and was taking gold from the Camonna Tong to reduce criminals sentences and fines, after they were killed, Varro rewarded the Nerevarine with the Ring of Surroundings and informed the Emperor of their deeds. The Moonmoth Legion rescued a Breton priest who had been kidnapped by the Erabenimsun Ashlanders, they also rescued an Imperial citizen from raiders near Gnaar Mok. Gnaar Mok also had a problem with a pair of breeding Netch that had become aggressive and were a threat to the village, which the Legion solved by killing them both. Furthermore, the Legion also dealt with a necromancer known as Sorkvild the Raven, in an effort to prove to the Dunmer that the Legion would root out necromancers no matter where they hide.
During the Oblivion Crisis, the Legion mainly found itself engaged in a stalling action against the incredible onslaught of Mehrunes Dagon. Leyawiin's Count in Cyrodiil complained that High Chancellor Ocato was inordinately concerned with other provinces even as Oblivion Gates opened throughout the Imperial Province itself. The denizens of Morrowind's Great House Redoran claimed that the Legions were recalled to Cyrodiil instead. Due to the Legion focusing on the other provinces, Martin Septim could not count on Legion support during the battle at the Great Gate at Bruma.
A company of Legion soldiers were traveling to the Imperial City during the Crisis in order to protect it from the Daedra, however, an Oblivion Gate opened in the middle of them, killing half of them. The Imperial Captain, Tertius Ione managed to save the rest and temporarily retreated, he then mustered together local farmers and hunters from the surrounding areas and from Pell's Gate. Ione returned with his remaining legionaries and freshly recruited auxiliary forces and slaughtered the Daedra, he then entered the Gate with about 52 men, whilst the other half guarded the gate. Due to Ione's sacrifice, a Bosmer named Fenton was successful in closing the Gate. The remaining Legion soldiers settled the area and named the settlement Ione in the Legion Captain's honor.
After the SeptimsEdit
Reachmen of BthardamzEdit
At an unknown point during the early 4th Era, an Imperial Spymaster known as Porcia Loran was in command of an Imperial Legion phalanx that were preparing to wipe out the Reachmen Doomfang clan at Bthardamz. However, her former subordinate Talym Rend was forced by Sheogorath to ensure Porcia would lose her sanity. Talym intercepted a Reachman letter detailing plans to use Dwemer Animunculi to deliver a deadly poison to the Legion's forces. Talym refused to show Porcia, instead planting false letter for her to discover. She was later captured by the Reachmen while seeking this false intelligence and was rescued by Talym. Porcia was led to believe that an antidote for the poison could be made using sacred flowers from a Grove of Mara by Talym's deceit. The priestesses of Mara refused to let Porcia have the flowers which drove her to personally assault the Grove and take them to save her men.
The Legion's alchemists refined these flowers into a gas that was meant to negate the effects of the poison. They were to deploy the antidote after the Reachmen had released the poison so as to make the best use of their limited supply. However the gas actually caused large explosions when it reacted with the poison, resulting in the death of most of the Reachmen and the legionaries. The outcome of her mission, whilst technically a victory, led her to retire from the Legion due to the fear of uttering a command that could potentially hurt others.
Following the Oblivion Crisis, the Imperial Legion steadily grew weaker. During the Umbriel Crisis, an undead army advanced on the Imperial City in an effort to take control of the White-Gold Tower, causing mass panic among its citizens. The Imperial Legion attempted to hold the line along the Red Ring Road, but were ultimately driven back to the walls of the city. The Synod and the College of Whispers worked together with the Legion to bring down the floating city, but also failed. In the end, Umbriel was banished by a group of heroes, but by that time the Legion already suffered heavy losses.
Night of the Green FireEdit
In 4E 42, Altmer dissidents who had fled to Sentinel from the Thalmor in Summerset Isle were attacked by Thalmor operatives. Their efforts to fight back against the Thalmor were in vain, and by the time Imperial Legion soldiers arrive, the entire refugee district of the city had been destroyed. The Dominion, not content with killing dissidents at home, came to Hammerfell to finish the job. An Altmer Legate known as Fasendil was one of the soldiers stationed there.
The Great WarEdit
The Thalmor rose to power again in the Summerset Isle, and the Legion could not stop them from reforming the Aldmeri Dominion. The Thalmor eventually delivered an ultimatum to Emperor Titus Mede II demanding a series of enormous concessions. When the Emperor refused, the Great War began. The Aldmeri Dominion initially invaded deep into the heart of Cyrodiil, capturing Leyawiin and Cheydinhal rapidly before the Legion could mobilize an effective defense. More Dominion armies invaded into Hammerfell, bypassing western Cyrodiil entirely. When they realized the weakness of the Legion, however, the Aldmeri Dominion grew bolder and mobilized an offensive against Cyrodiil as a whole, intending to bring the entire Empire under their control. Quickly, Bruma and the Imperial City were the only cities that remained under Legion control in Cyrodiil. Meanwhile, the legions in Hammerfell were pressed hard and forced to retreat, leaving the entire southern half of Hammerfell to fall to the Dominion. The Imperial City itself came under siege. Though relieved by several legions of hardened Nord legionnaires, the Emperor ultimately gave the order to break the siege and abandon the city. An entire Legion sacrificed itself to defend the Emperor's rear.
At this time, the Imperial Palace was sacked, plundered, and burned with the Aldmeri Dominion seeking an Imperial surrender. While the Emperor strung them along, he recalled all the legions defending Hammerfell and rearmed and refreshed the Skyrim and Cyrodilic legions. However, General Decianus allowed a great number of "invalids" to be discharged from the Legions before they marched east in an effort to drive the Altmeri back from Skaven. These veterans formed the core of the army that eventually drove the Altmeri General Arannelya's forces back across the Alik'r late in 174, with the Dominion forces taking heavy losses on their retreat from harassing attacks by the Alik'r warriors. This successfully duped the Thalmor into believing the entire army was still fighting them there. The Emperor stormed south with his refreshed legions as the Hammerfell legions came in from the west. The Aldmeri Dominion, caught by surprise, was attacked by the Hammerfell legions from the west, while the Skyrim legions swept east and south and the Emperor, along with his personal Cyrodilic legions, assaulted the Imperial City, surrounding it on three sides and fending off Dominions piecemeal reinforcements and blocking their retreat from the Imperial City. They retook the Imperial City and all of Cyrodiil. In the end, the Legion was victorious, though exhausted, no Legion had more than half its forces fit for duty, and Two Legions of soldiers had been effectively annihilated, not including the loss of the Eighth Legion in the retreat from the Imperial City the previous year. But the Emperor believed that with this victory was the best time to negotiate peace with the Dominion and put an official end to the war, resulting in the White-Gold Concordat being signed, which essentially gave in to all the Thalmor's initial demands. Hammerfell, however, was unwilling to concede defeat and the loss of so much of their territory, and so, in order to preserve the peace with the Dominion, the Emperor officially renounced Hammerfell as part of the Empire.
Skyrim's Civil WarEdit
Unfortunately, the Legion's woes were not yet at an end. In Skyrim twenty-five years later, with the ascension of Ulfric Stormcloak to the Jarlship of Eastmarch and the death of High King Torygg at Ulfric's hands, civil war broke out. The Imperial Legion was forced to fight in Skyrim against many warriors who had previously been legionnaires themselves, weakening the Legion even further.
Armor and ArmsEdit
Legionnaires are specially outfitted depending on a large number of factors, including climate, location, task, and expectations. They employed armors of chain, scale, plate mail, and gender-neutral skirts in the province of Morrowind in 3E 427, heavy steel plate overlying chain mail in the capital province of Cyrodiil during the Oblivion Crisis, and lighter leather, chainmail, and steel plate armors in Skyrim during the Stormcloak Rebellion. Battlemages tend to wear hoods, healers wear light padded armor, guardsmen on loan to nobles wear the vestments of their town, city, county, or hold, and rangers and foresters tend to wear fur or leather apparel in addition to their Legionary armor. Dragonscale armor and shields are also used, with the craft coming from Akavir and being implemented since the Reman Empire. In addition, the uniform may vary depending on the culture of the local area or province.
Legion foot soldiers mainly use Imperial swords, steel swords, and Imperial bows. However, other weapons are often used as well, such as broadswords, shortswords, spears, pikes, claymores, axes, daggers, warhammers, maces, and staffs.
The Daggerfall Covenant based their armor designs on Reman Era Legion armor, with their chest pieces as an example. The Order of the Hour also based their armor design on that of the Second Era legions.
