A wizard whose insatiable desire for arcane power eclipsed their mortal life, the lich is a truly devious and versatile spellcaster.

To gain more time to complete their goals, some desperate spellcasters pursue immortality by embracing undeath. After long years of research and the creation of a special container called a soul cage, a spellcaster takes the final step by imbibing a deadly concoction or casting dreadful incantations that transform them into a lich. While most undertake this drastic plan to continue their work or fulfill some long-term plan, others become liches because they fear death or to fulfill some malevolent purpose, such as long-sworn revenge. Regardless, the result is permanent and carries with it the potential to alter history-both that of those who transform themselves and of the countless mortals that will inevitably suffer as a result of a lich's new power.

After its metamorphosis, a lich often finds some quiet place to dwell, typically protected by a variety of guardians and traps, for two primary purposes. First, a lich requires solitude in order to plan its elaborate schemes, and second, few mortals (if any) deign to interact with these legendarily corrupt necromancers. One reason begets the other, as the self-imposed isolation of a lich often drives the lich insane, further solidifying its separation from civilization. The longer a lich lives, the more meticulous a planner it becomes, secreting itself within a labyrinth of deadly puzzles, misdirection, and monsters. A lich's servants and guardians are absolutely loyal, either due to their nature (such as constructs or other undead) or as a result of compulsion using powerful magic. Many liches go mad, in time, and the nature of a lich's lair is a good indicator of the undead's current mental state.

For all the protections it arrays around itself, a lich will go to greater lengths to guard its soul cage, as it knows that the destruction of this magical container spells doom for the lich. A lich is notoriously difficult to bargain with, though the threat of damaging its soul cage is a sure way to gain the upper hand in such a negotiation.
