The Underking is a title of uncertain origin that has been attached to a number of supernatural beings throughout history. Individuals who bear this moniker include:
- King Wulfharth (Ysmir), avatar of Shor, who fought the Tribunal at Red Mountain, was an ally of General Talos (then advisor of his son, Pelagius I) and lived and died three times. In one of his lives, he defended Tamriel from an Akaviri invasion, alongside Almalexia.
- Zurin Arctus, who either betrayed or was betrayed by his master, Emperor Tiber Septim. He also destroyed Numidium twice.
The controversy on the identity stems from the fact that although most sources call Arctus the Underking, there are some sources, such as The Arcturian Heresy, that call Wulfharth the Underking. For more information on the two, see their respective Lore articles.
- According to one theory, Wulfharth, Tiber Septim, and Zurin Arctus can all be regarded as parts of the same enantiomorphic Oversoul that makes up the deity known as Talos.
