This here's Magnus. Following the Calamity, Fyrilsunn found himself a sailor without a ship. So he decided to start adventuring. One day he was walking past the chocobo stables in Limsa, and learned that they where getting ready to 'retire' an old charger. Fyrilsunn decided to take the bird, figuring it was still fit enough for his needs. He quickly found that the old warbird had plenty of fight left in him.
Magnus is crotchety, squawks at everything, and will nip your arse if you're not looking. But he's loyal, fearless, well trained, and has no qualms with pecking the shit out of a monsters face when called for.
