Urvo was an otter in the Bark Crew, and a part of Brogalaw's holt. During the last stand of the Crew, Brog asked Radd, Trobee and himself to fetch double quivers and bows so that they could hold the rear. It is unknown if he survived the skirmish, and the ensuing siege of Salamandastron. He was a minor character, and nothing else is known.
