A world-spanning campaign for Warhammer Fantasy Roleplay.
From the back cover:
The Thousand Thrones is a campaign for Warhammer Fantasy Roleplay, promising to take adventurers from the stinking canals of Marienburg to the western fringes of Kislev. When a boy with a burning twin-tailed comet on his chest single-handedly kills a pair of cultists, he is proclaimed to be Sigmar reborn. Supported by a legion of fanatical followers, the player characters are drawn into a dangerous and sinister story involving ancient evil, the cults of Chaos, the lords of night and a veritable army of other deadly foes.
