Acererak

Acererak (pronouced "ah-SAIR-ak") was a powerful archlich that was known and feared by many in the multiverse. He visited Toril in the late 1480s DR to place an artifact of his creation called the Soulmonger in the Temple of the Nine Gods, causing the onset of the Death curse.

Personality
Acererak traveled through the multiverse in search of artifacts, which he liked to lock away in trap-ridden dungeons to watch adventurers suffer and die. He then enjoyed trapping their souls in his phylactery, whose location was unknown.

History
At some unknown time not long before the late 1480s DR, Acererak traveled to the Negative Energy plane and found an atropal there, which he decided to nourish to godhood. For that purpose, he built a powerful artifact called the Soulmonger and placed it in one of the tombs he possessed, the Tomb of the Nine Gods in Chult. The tomb served as the atropal's nursery while the artifact nourished it by trapping the souls of the dead and draining the souls of those who had been beneficiaries of resurrection magic. This was known as the Death Curse
