Teneb Trismegistus, Doctor of Theoretical Planar Physics, is a lich servant to Twilight, the God of Darkness. He resided in the Obelisk of Darkness in the Mhojave Desert, where he conducted his research on planar travel. Quite the diabolical fiend, Teneb wields enough power to level entire cities, though his body appears frail, the deceptive visage of a decaying corpse hobbling about painfully.
He regularly corresponds with fellow Darkwalker Sharbrena through notes, but Teneb seems careless in keeping them safe, as they are often blown throughout Sapience, thus exposing the plans written upon them to the world.
