The Edge of Night
A demonic entity that thrives on mortal political and social dynamics, Dajjalasa embodies and promotes secrecy and ignorance. She is said to have cursed the blind and deaf. She opposes the accumulation of knowledge and wisdom, and is a particular enemy of sages, magoi, and the Oracles. She is a member of the Tribe of Night, presiding over deception, secrets, and betrayal.
In part, Dajjalasa is credited with the relative lack of knowledge that scholars have about the Tribe of Night, as her servants and unwitting agents are responsible for destroying collections of lore, killing or maddening the wise so that knowledge is not passed on, and sabotaging those who would learn about matters arcane and spiritual. She seeks to preserve the obscurity and mystery of herself and her brethren so that they may continue to operate unopposed.
