The lich Acererak—a powerful wizard and demonologist and the infamous master of the Tomb of Horrors—anticipated his own transformation, preparing for it by setting enchanted gemstones into his skull's eye sockets and teeth. Each of these soul gems possessed the power to capture the souls on which his phylactery would feed.",

If the skull that was his last physical remains was ever disturbed, its gems would claim the souls of the insolent intruders to his tomb, magically transferring them to his phylactery.",

As their patron did, they secure their remains within well-guarded vaults, using soul gems to maintain their phylacteries and destroy the adventurers who disturb their lairs.",
