From the back of the book:
Beneath an ancient keep on the borderlands, reclaimed from the ruins of a lost civilization, there is a dark and deadly tournament being held. Seven stalwart adventuring companies, each representing a wealthy noble house, delve into the depths of the Dungeon of the Black Fey Mithelvarn in a race to be the first to claim the power of the Infernal Machine that drives it, and the Elixir of Immortality it contains. Can your party take up one of the Relic Banners and face the challenge of the dungeon as well as the lethal competition from the other companies seeking the prize?
