Liches are one of the most feared adversaries one can encounter in the Underworld. Old, powerful and full of hate, liches were once powerful wizards who, in a desperate bid for immortality, have sacrificed their souls to gain forbidden knowledge and eternal life as an undead necromancer. Forever damned, liches sit on their thrones of bone awaiting the time when their powers are strong enough for them to rise up and dominate the living.
Among the known Liches, the wizard Tyball has become a powerful lich after his death at the hands of the Avatar.
Occasionally, an extremely old and powerful wizard will choose not to suffer a natural death, but instead become a liche. In such cases, their bodies die, but their minds live on and animate the rotting corpse. Liches are in nearly all cases solitary, most being scholars who carry out magical research in secret. Anyone capable of becoming a liche must already be highly intelligent and a master of arcane knowledge. In most cases, a liche is also completely insane.
- Liches previously appeared in Ultima Underworld II: Labyrinth of Worlds.
- Morphius, Lord Umbria and Lethe (the Three): A triumvirate of ultima:Praecor Loth's former retainers who bar access to the dead king's final resting place in Ultima Underworld II.
The Lich is part of the $900,000 Stretch Goal rewards.
