Odheirs

Odheirs is a fictional entity featured in the tabletop role-playing game Dungeons & Dragons. Within the Forgotten Realms setting, Odheirs is known as a powerful undead being, specifically a lich. Liches are ancient and exceptionally powerful spellcasters who have achieved immortality through dark magic, sacrificing their mortality to become undead. The process of becoming a lich is a forbidden and terrifying ritual, requiring immense arcane knowledge and a willingness to engage in horrific practices. Once transformed, a lich retains its intellect and magical abilities, often vastly amplified, while becoming immune to many of the vulnerabilities of living beings. They typically reside in hidden lairs, often ancient ruins or magically protected fortresses, where they continue their studies and pursue their own sinister agendas. Odheirs, like other liches, is driven by a desire for power and a thirst for forbidden knowledge. Its existence poses a significant threat to any adventurers who might stumble upon its domain or cross its path. Defeating a lich is a monumental task, often requiring the destruction of its phylactery, the magical object that houses its soul and allows it to regenerate if its physical form is destroyed.
