Acererak, a half-human lich, was one of the nine Lich-Lords of Alokkair; who grasped at godlike power only to lose his grip on reality.

Only a few bards and scholars remember Acererak’s name, but many know the legend of his supposed final resting place; the Tomb of Horrors. As rumors of the wealth and magic hidden in this fabled location spread, the tomb became a burial ground for more and more explorers and tomb robbers.

In truth, however, the Tomb of Horrors was not Acererak’s sepulcher at all. It was merely part of his plan to gain eternal un-life and command of his ndead servants. Acererak left behind a diary, and the information it contained, combined with the actions of a stalwart few, have at last brought the full tale of Acererak into the light.

In his diary, Acererak wrote that he was born of a union between a human woman and a demon. Despite his hideous deformities, his mother kept him and cared for him until he was tenyears old. That year, some superstitious villagers burned down their house. Acererak survived the conflagration because of his demonic heritage, but his mother did not. Acererak later recalled that incident as the event that propelled him on the path toward necromancy and revenge against humanity.

Overthe years, Acererak became a powerful wizard. As he grew older and saw the specter of death looming, he sought out and completed the ritual for becoming a lich. After he assumed his undead form, his power continued to grow for centuries more. Acererak eventually felt the forces animating his undead body begin to wane. Knowing that final oblivion was near, he decided to build himself a secret tomb.

“Only those of keenest luck and greatest skill will win through to me,” the diary read. “There, they shall receive a magnificent reward for their persistence.” The diary, the Tomb of Horrors, and the supposed reward were all parts of an elaborate ruse designed to bring powerful adventurers into the portion of the tomb that Acererak—by then a powerful demilich—called his Fortress of Conclusion.

Known by few, Acererak actually devised a ritual that he hoped would merge his consciousness with the Negative Energy Plane through the sacrifice of potent spirits. Had he actually accomplished this goal, he could have assumed control of any undead on any plane and gained godlike powers as well as immortality.

But the infamy of the Tomb of Horrors drew more than wealth-hungry thrill-seekers intent on gaining the reward promised in Acererak’s diary. Supplicants also came. Necromancers questing for knowledge, seekers of eternal life, and lost souls in search of purpose traveled to the tomb to learn what they could of the dark arts. In time, the supplicants became worshipers, and they stayed to dwell near the object of their devotion. Eventually, a settlement called Skull City sprang up around the entrance to Acererak’s Tomb of Horrors.

Some of the heroes Acererak lured to his tomb proved even more powerful and ingenious than he had anticipated. After fighting their way through Skull City and the Tomb of Horrors, they made their way to the demilich’s Fortress of Conclusion. At the last possible moment, they surmised Acererak’s plan and destroyed the artifact that was crucial to his apotheosis. They struck down Acererak and shattered his phylactery.

Normally, such an action would have sent Acererak’s spirit to Abyss, but the worship of the Skull City residents lent him a semblance of divinity; his desire to merge with the Negative Energy Plane proved stronger than the pull of the Abyss. Unfortunately for Acererak, souls do not travel to the Negative Energy Plane upon death. Since his spirit had no clear destination, it went nowhere, becoming a vestige divorced from all planes.
