Teneb' Trismegistus, Doctor of Theoretical Planar Physics, is a lich servant to Twilight, God of Darkness. He resides in the Obelisk of Darkness somewhere in the Mhojave Desert where he continues his research in Planar Travel.
He corresponds regularly with his fellow Darkwalker, Sharbrena in the form of notes but seems careless in keeping them safe as they are blown about Sapience, exposing their plans to the world.
Almost as powerful as the legendary Dark Servant, Danaeus himself, Teneb is a diabolical fiend. Although he wields the power to level entire cities, his body is deceptively frail, appearing as a decaying corpse that hobbles painfully.
