Rook witnessed the convocation, by following Wemeru. He hung onto a branch and took notes in his treatise log. However, his hand slipped an the log fell out. Rook tried to grap it but was caught when he fell off. As it was forbidden for non-banderbears to witness the congregation, Rook was in massive trouble. Most of the banderbears agreed to kill him. Fortunately, Wuralo begged for his life to be spared, and he was accepted as a friend of banderbears.
