The Mythic Dawn was led by the 'madman' Mankar Camoran, whose son Raven and daughter Ruma were his key lieutenants all three were slain by the Champion of Cyrodiil. Their deaths brought about the Oblivion Crisis, which resulted in a Daedric invasion of Tamriel and the end of the Third Era. The cult carried out an assassination plot against Emperor Uriel Septim VII and his heirs in 3E 433. The cult's existence can be traced back to the early days of Tiber Septim in the Second Era. The Mythic Dawn was a secret cult that worshipped the Daedric Prince of Destruction, Mehrunes Dagon.
