Once a proud and fearsome red dragon, he was stripped of his power and his wings and made to “do good”, while sealed within a small, plushie body… thankfully, he can summon a vestige of his former glory! …even if it’s very restricted…
He’s an angry little guy, prone to ranting when he feels disrespected, but he’s ultimately harmless. He also can’t bring himself to admit that he’s kinda enjoying being such a little guy people like to pick up and hold. While he still has evil draconic tendencies, the vessel is enchanted to make him follow the Code of Conduct, meaning he can’t act on his impulses.
In PF2e, Aurumvorax is a toy poppet summoner, whose dragon eidolon is himself!
