Sersei is a young goblin girl of the Red Fang tribe noted for unusual intelligence and the rare ability (among her kin) to read human writing. Favored by the late elder, she has become invaluable after the witch’s death by translating the witch’s hidden journals for Scribs and Pex. Shrewd and self-interested in a childlike way, she bargains for small rewards—like a frog leg and promises of future theft—while still aiding the tribe’s survival through knowledge.
