From the introduction:
The adventure can take place in any campaign setting that has liches, vampires, and undead creatures of all kinds. It revolves around a town called Glamroa, a mediocre town ruled by a group of people calling themselves the Glamroan Triad. They include a paladin-king, a powerful mage, and a priest lord. Unknown to the townsfolk though, they are really undead creatures of great power. The paladin-king is really a Human Vampire Fighter/Mage 19/23 that has been undead for about a century now. The mage is a powerful Lich who serves the vampire. The priestess lord is really a Greater Mummy. They keep in disguise and hardly venture out of their palace.
