A lich is a powerful undead creature found in the world of fantasy, particularly in Dungeons and Dragons settings. They are the ancient, powerful remains of sorcerous, magical, and undead beings that have been transformed after death into a powerful entity. Liches possess a powerful magical presence that often makes them one of the most dangerous opponents for an adventurer to face. Liches are often believed to represent a form of immortality due to their immortality and longevity, as they can come back from death multiple times, as well as transferring their consciousness and power to a phylactery. The phylactery, or Lich's Soul Jar, is an item that is used to bind and store a Lich's soul. This allows them to return from death and sometimes even live on as multiple versions of themselves. Liches have a strong presence as enemies and seek to increase their power by any means necessary. They are often a formidable foe to adventurers due to their magical prowess, as well as the knowledge and experience they have gained over the years. Ironically, Liches are often frustrated by the mortality of their victims and, as such, will sometimes make them offers for them to join them in life after death and share in their power.
