Publisher's Synopsis
Bran Mak Morn, King of the Picts, vows vengeance on Titus Sulla, a Roman governor, after witnessing the crucifixion of a fellow Pict. He seeks forbidden aid from the Worms of the Earth, a race of creatures who Bran Mak Morn's ancestors banished from their kingdom centuries ago. They were once men, but millennia of living underground caused them to become monstrous and semi-reptilian.Searching for a contact with these creatures, Bran Mak Morn encounters a witch who lives in a secluded hut, shunned by her neighbors, who was born from a sexual encounter between one of the "Worms" and a human woman. The witch's price for helping him is "one night of love" which her human-half craves - as men in general are repelled by her reptilian traits. Bran Mak Morn, though also himself repelled, agrees to pay the price. In exchange, she tells him of a barrow where "The Black Stone", a religious artifact of great importance to the "Worms", is hidden.
