Rocangus the falcon was the son of Lord Mactalon, the ruler of a falcon tribe in the Northern Mountains. His wing was fractured in a battle with a large flock of crows. He was then found by the mousebabe, Dumble and Thrugg the otter, who were journeying to find the Flowers of Icetor, the only cure to the sickness that was plaguing Redwall Abbey. The otter splinted Rocangus' wing for him, and the falcon joined the search. Rocangus was a bit unusual in that he was said to come to enjoy sitting by a fire during his travels with Thrugg and Dumble (presumably, most other birds are afraid of fire).
