I know you already have a cleric, but this one is a slightly different cleric. Sarnath is a Elder Mythos Cultist of Bokrug, the Water Lizard, with the Daring Doomsayer campaign trait from Varisia, Birthplace of Legends. His main combat ability is Channel the Void, which can harm living and undead alike, though he can swing a ranseur (or Doomsayer's Placard) if necessary. Outside combat, he has the esoteric knowledge granted to him by his extensive research and haunted dreams, and a little bit of face.
