From publisher blurb:

Eight We Are, Eight We Shall Be.
United, Indivisible, Eternally.

So reads the first clue to the mysterious past of the Blades of Cara Fahd, a set of near-identical daggers forged in the time before the Scourge. A quest to learn the history of the Blades and unlock their magical power takes the daggers' new owners across Barsaive, from the ancient ork kingdom of Cara Fahd to the dark heart of the Tylon Mountains. But the Blades also hold a terrible secret, long lost to time and memory, that threatens to wreak havoc throughout all of Barsaive!
