Perriso

Perriso first appears in Book 8 as a colossal mammoth mount whose square cage saddle and glowing shield mark him as a formidable battlefield asset. His introduction in "A Parade of Horribles" signals a shift in Carl’s tactics, replacing earlier, smaller mounts with a living siege engine capable of carrying multiple crawlers and heavy gear. The mammoth’s shield aura and sheer size suggest he will play a decisive role in the escalating war between crawlers and the Dungeon’s ruling powers.
