Surt told you that one of the tombs of the Red Sky Legion--protected Brusthonin from Balaur--had been desecrated. When you went to investigate, you found a broken sarcophagus and no sign of its occupant, Villaire. After consulting Theia the wandering ghost, you met Seznec, an old man with knowledge of spirits. He made a potion to call forth the spirits of the other members of Red Sky Legion. Unfortunately, none of them had useful information.
