lichdom

Lichdom refers to the condition or state of being a lich, a type of undead spellcaster who has achieved immortality by binding their life force to a phylactery. In fantasy fiction and role-playing games, a lich typically retains intelligence, magical power, and memories after death, albeit in a withered or undead form.

Origin and terms: The term lich derives from the Old English word lic, meaning corpse, and has been popularized in modern fantasy to describe a mage who defies death. A defining feature is the separation of the soul from the mortal body, using a phylactery to house the essence.

Mechanism and vulnerabilities: A lich preserves its existence by anchoring its soul to a phylactery, an object that can survive decapitation or bodily destruction. The body may rot or wither, while the soul remains intact and capable of reanimation when the body is damaged. The destruction or corruption of the phylactery typically ends the lich's existence. Some settings impose additional conditions, such as a ritual, ongoing life energy requirements, or a vow to avoid harming the phylactery.

Role and legacy: Liches are commonly depicted as powerful and secretive artificers who manipulate events from the shadows. They often serve as major antagonists in fantasy literature, video games, and tabletop role-playing games, embodying themes of hubris and the corrupting nature of immortality. Variants include god-kings, undead rulers, and bound souls who continue to plot across centuries. Notable examples in popular culture include Vecna in Dungeons & Dragons lore, the Lich King in Warcraft, and Ainz Ooal Gown in the light novels and anime Overlord.
