Risra Ironback was an otter in The Bridge. He was like a brother to Adrian Greenlough, and frequently helped Adrian's mother, Iris. Risra was the first to notice Adrian's and Iora's connection, and he advised against it, however, when it became obvious that neither was going to listen, he stepped out of their business. Risra was the one to tell Iris about their relationship, forcing the two to run away. After Adrian and Iora returned, Risra was the first to support them, sparking others to do the same.
