The Ket Keptu, also called the Men-of-Ket or simply Keptu, were an ancient race of Men native to central Hammerfell and the hinterlands bordering Cyrod, such as the Jerall Mountains. They lived in Tamriel during the Merethic and early First eras, alongside many of the other early Nedic peoples. Though unpolished and barbaric, the Keptu were far from primitive, and were among the earlier pre-Alessian civilizations to discover techniques for refining ores. Their culture was at one point almost entirely oral, though they had developed glyphs and amulets inscribed with markings.
With the aid of Hircine, they constructed the Bloodroot Forge atop a large source of nirncrux in a secluded Jerall valley, a massive and powerful magical forge rivaling the architectural feats of the Ayleids and Dwemer. It harnessed the power of lava flows to smelt the tribe's ore and heat their metals, though also served a more occult purpose as a temple to worship dark gods and practice dangerous rites of Blood Magic with the use of iron, nirncrux, and lava. The Ayleids enslaved many Keptu around the Niben during the early First Era before their empire fell. Due to the usage of "Nede" as a catch-all term for Merethic Era humans, the Keptu are inconsistently described as being Nedes and as a separate race from Nedes. Pelinal Whitestrake brought Morihaus to the Nedic healer Zuathas the Clever-Cutting man, who had a Keptu name and tended to the wounds he received after a battle with the Ayleids.
How the Keptu people faded from prominence is unclear, but most Nedic cultures were already in decline by the time the Ra Gada set foot in Volenfell circa 1E 808. It is suggested that they had ancient cultural interchange with the clans of the Reach, who adopted parts of their cultural styles. By the Second Era, ancient Keptu sites had become ruins and were shunned by the Nords as places of evil. In 2E 582, a group of Reachmen descended from the Keptu formed the Dreadhorn Clan with their minotaur allies after their leader Gherig Bullblood met with the minotaur Domihaus the Bloody-Horned, who recognized his Keptu amulet. Together, they used Blood Magic to reawaken the Bloodroot Forge, meddling with the long-slumbering smithies to infuse themselves with nirncrux. The Dreadhorn Clan used this power to put the Nordic city of Falkreath under siege, but this was lifted after Domihaus fell in battle.
