Bab 80: Chapter 80 Zebuzal

Ybur ran and ran, not stopping until he had put a good distance between himself and the hellish scene behind him. It wasn't until the agonized screams of the Rat People were no longer audible that he finally allowed himself to breathe a sigh of relief and feel a small sense of safety.

That guy just now…

The powerful necromancy and those skeletal hands… that guy must be a Lich!

Suddenly, Ybur felt cold sweat streaming down his back.

A Lich is a special entity transformed through a Lich Transformation Ritual created by the Endless One, generally chosen by spellcasters who seek either immortality or to make a further breakthrough in the art of necromancy.

This is both a type of undead creature and a unique casting profession.
