There are at least sixteen major Planes of Oblivion, each ruled over by one of the Daedric Princes, and over 37,000 other documented planes, including chaos realms and pocket realities, although there exists far more than that. Most realms are maintained by greater Daedra, although some are ruled by mortals who have ascended to immortality—like the Ideal Masters. The realms of the Daedric Princes can be very extensive;
The 16 main Daedric planes along with the Daedric Princes they are associated with are:
- Apocrypha, Hermaeus Mora's realm.
- Ashpit, Malacath's realm.
- Coldharbour, Molag Bal's realm.
- The Colored Rooms, Meridia's realm.
- The Deadlands, Mehrunes Dagon's realm.
- The Evergloam, Nocturnal's realm.
- The Fields of Regret, Clavicus Vile's realm.
- The Hunting Grounds, Hircine's realm.
- Moonshadow, Azura's realm.
- The Myriad Realms of Revelry, Sanguine's realms.
- The Pits, Peryite's realm.
- Quagmire, Vaermina's realm.
- The Realm of Boethia, Boethiah's realm.
- The Scuttling Void, Namira's realm.
- The Shivering Isles, Sheogorath's realm.
- The Spiral Skein, Mephala's realm.
Each plane is different in appearance, depending upon the nature of its ruler. They can range from beautiful to desolate; some are even too strange for mortal comprehension.
The Odai River, also called River Odai, was a river running north to south on the island of Vvardenfell in Morrowind. It began in the West Gash region just north of Balmora and flowed placidly through the center of the city to the Odai Plateau. It then passed through the Ascadian Isles region before emptying into the Inner Sea at the eastern edge of the Bitter Coast near the town of Hla Oad. The terrain surrounding much of the river was mountainous and dotted with mines. A rough track along the western shore of the river connected Hla Oad with Balmora. It's unknown how the river was affected by the cataclysms of the Red Year.
Ogres Tooth MountainsEdit
The Ogres Tooth Mountains are a range of mountains on the island of Stros M'Kai in the kingdom of Hammerfell. They are found to the west of Port Hunding and take up roughly a third of the available land area.
The mountains are notable for the Dwemer ruins of Bthzark. Its mines and other facilities delve into the southern half of the range, while the steam and gas harvesting system that powers the mechanisms inside lie above ground in the northern mountains. Two large bridges cross a pass that cuts the range in two, and the steam pipes cross with them.
Old Hroldan (also spelled Old H'roldan, Old Hrol'dan, H'roldan, as well as Ahroldan in the language of the dragons) was a settlement in southwestern Skyrim. The Pocket Guide to the Empire, 1st Edition, stated the town was in High Rock. It had been taken over by the Witchmen of High Rock before Tiber Septim famously reclaimed it in the late Second Era at the age of twenty.
Reclaiming Old Hroldan from the Witchmen, or Reachmen, was something of a pastime, as an ancient property record belonging to the Jarl of Whiterun refers to "H'roldan" as "A Spacious Wooden Hall and Pasturage, recently Seized from the Reachmen. Silver and Iron as Tribute from the Natives." Other records note that in 1E 2801, Emperor Kastav of the Reman Dynasty ordered hostages to be seized from the town to ensure the jarls met conscription quotas.
Though formerly a walled and gated city, by the Fourth Era the settlement has been reduced to simply the Old Hroldan Inn, a resting place for travelers in the Reach. The inn, which is wedged between ruins, mountains, and rivers, boasts to its patrons of harboring Tiber Septim the night he arrived. Sightings of ethereal warriors at the inn coinciding with the appearance of the Last Dragonborn gave credence to the inn's claim.
Oldgate (also spelled Old Gate) is a fortified gate located on the border of the region of Rivenspire, situated within the province of High Rock. Oldgate serves as the regional bulwark for the city of Shornhelm, and a gateway between Rivenspire and Stormhaven. It works adjacent with Newgate, which is found in Stormhaven instead of Rivenspire. It is the home of the Oldgate Lancers.
The island originally hosted a significant city, although it was abandoned sometime in the Second Era. Tiber Septim used Olenveld as his own personal graveyard, lining its abandoned streets with gravestones. Eventually the island city was forgotten, and Olenveld disappeared from the maps.
After Hannibal Traven became the Arch-Mage of the Mages Guild circa 3E 431, he introduced a ban on necromancy in the guild. Forced to go into hiding, a group of necromancers set out to find Olenveld and its plentiful supply of bodies. After spending a week searching for the island, they set up shop in the old Mages Guild building and became somewhat well-known for their ability to preserve sickly children by turning them undead.
Necromancers still inhabited Olenveld several centuries into the Fourth Era. In 4E 201, two necromancers set out from Olenveld in order to open a portal to the Soul Cairn. They established themselves within Brittleshin Pass in mainland Skyrim, where they managed to acquire the Staff of Hasedoki via the local smugglers. They planned to release Hasedoki's soul from the staff to earn the favor of the Ideal Masters, although they were both killed by the Last Dragonborn before this could occur.
The Oliis Bay is a large body of water found in southeast Black Marsh, forming the east coast of Murkmire. The name comes from the Imperials, when they laid claim over the province's coastlines. The city of Lilmoth is found on the bay mouth, which empties from the Southern Sea.
Onkobra River is a fast-moving stream that runs into the dark center of Black Marsh from various points in the province. One of the river estuaries of the Onkobra runs around the city of Gideon, along a muddy and dysfunctional road. This estuary is found near the Topal Bay. There is another portion of the Onkobra in the region of Shadowfen, south of the port-town of Alten Corimont. The Dark Elves had established a Kwama Mine called the Onkobra Kwama Mine, but when Argonian slaves were able to overwhelm their slavers, they took over the Kwama Mines in Black Marsh, including the Onkobra Mine. This, however, did not end successfully. All the while, armillary spheres showcasing the Aurbis etched in Onkobra Kwama Eggs were in circulation in 2E 582.
Orcrest is one of the eight-major cities in the province of Elsweyr, situated on the barren canyons of Anequina. Orcrest is known as the center of commerce in Northern Elsweyr, built atop of a plateau that overlooks the harsh desert of the Scar, with ancient walls and great bridges across the canyon. Orcrest was one of the original sixteen kingdoms of Elsweyr, known for their rogues and thieves.
Orsinium (which literally translates to "Orc-Town" in Aldmeris) is the city of the Orsimer and the provincial seat of the region of Wrothgar, which came to be known as the Orsinium Area in the late Third Era. It has been sacked and rebuilt many times over the centuries, as the Orcs are often at odds with their Breton and Redguard neighbors. Orsinium was first built in High Rock, straddling the boundary between western Wrothgar and Rivenspire. In the mid-Second Era, the city was relocated to eastern Wrothgar. In 3E 399, it was relocated again to a site between Wayrest, Menevia, and the Wrothgarian Mountains. By 4E 201, Orsinium had been moved a third time, farther south to an area between Hammerfell and Skyrim.
The Orsinium Area was a Third Era political entity situated in the Iliac Bay region, inhabited by Orcs and ruled from the city of Orsinium. It bordered Menevia, Wayrest, and the Wrothgarian Mountains. The Lyrezi clan was the predominant vampire bloodline in the region.
After the Warp in the West, the region became a part of the larger kingdom of Orsinium.
Othrenis (alternatively called Eagle Moor[nb 1]) is a necropolis located in the region of Stonefalls, within the province of Morrowind. Othrenis contains the remains of the group of mages that sealed the Brothers of Strife during the First Era. Their leader, Mavos Siloreth is kept at the largest crypt of the necropolis, which overlooks the entire area.
