Father Luis Gomez was the youngest of the twelve members of the Consistorial Court of Discipline. His dæmon was an iridescent green-backed beetle. He was sent by the Magisterium to kill Lyra Silvertongue or Mary Malone before the prophecy of the witches coud be fulfilled; but before he could complete this mission, Balthamos killed him both by separating him from his beetle dæmon and by pushing his head underwater, drowning him. Seconds later, Balthamos died from multiple bites from Gomez's beetle dæmon.
