Far in the future, bards sing tales of kings and conquerors from ages past - but from your present. The Hero-Kings of legend are your player characters from your campaign, who even now shape the course of Cerilian history. More than simply an adventure collection, this 160-page book enables you, the Dungeon Master, to turn ordinary domain actions into oppurtunites for heroic exploits. Each of the eleven "legends" set forth here is based on a different random event from the BIRTHRIGHT Rulebook. Don't allow a mere die roll to decide the outcome of a blood challenge, rebellion, intrigue, or magical event - make the PCs forge their own destinies by confronting a madman who is "Blood Hungry," wresting the "Fang of Kriesha" from its evil wielder's grasp, thwarting a rival regent's "Double Dealing," and saving all of Cerilia from "The Gift of Azrai." These adventures are suitable for PCs of all levels and classes - wheter regents, scions, or commoners - and can take place wherever you campaign is set. This book also includes an appendix that offers advice for running different types of BIRTHRIGHT campaigns and creating your own adventures fit for a king. TSR 3125

The kuo-toa are a piscine race with a psychic affliction that makes them behave erratically and invent gods when feeling threatened. That same affliction gives them the power to bring those gods to life. Blibdoolpoolp is the most widely worshipped, and thus most powerful, of their gods. Blibdoolpoolp views the kuo-toa as her children despite having been born after them. Like all good mothers, she nurtures and protects. One of her chief concerns is understanding the kuo-toa’s psychic affliction, which causes them to undermine themselves whenever they strive for greatness. She discovers that a corrupted elder brain deep in the Underdark has a connection to the race; though the connection gives them psychic powers, it also turns them into powerless thralls, explaining their self destructive behaviors. Constrained by the same leash on her children, Blibdoolpoolp seeks adventurers to destroy the elder brain. Its death would free the kuo-toa, but potentially at great cost: if the kuo-toa lose their powers, will Blibdoolpoolp die?
