The Eleven Baneful Gates. This ancient scroll is thought to contain the secret of immortality, symbolized by eleven tests or riddles. The work was bestowed by a prophet of the gods on a wizard-king (perhaps one of the Necromancer Kings). According to legend, this king sundered his realm after becoming immortal, leaving nothing in his wake but sand and dust.

Copies of the original are known to exist, and these rare books cover in full detail the various rites involved in becoming a lich. The process requires a powerful necromantic potion and a wizard of at least 18th level (in order to survive the transformation at least). This work is one of the books most coveted by necromancers and would-be liches alike.
