Callisto is an absolute scaredy cat who adores comfort. Warm baths, pretty views, good food, all make him endlessly happy, but he is scared by everything and everything. He'll venture into dungeons with his best friend/found family Tiber, and if anything threatens/happens to Tiber, it's the one time that Callisto is truly menacing, as he'd do anything for Tiber More often than not, he gets spooked and ends up accidentally knocking other horses into harms way as he runs for the exit, but despite this, he's almost universally loved because he's an absolute sweetheart and kind to everyone
