Aggrim was a thin, one-eyed male ferret in the Ravagers under Zwilt the Shade. While he was helping his leader track some vermin deserters, he and another ferret named Feril discovered Buckler Kordyne and his companions, who were searching for their lost babes. The Ravagers ambushed the woodlanders from both sides and Aggrim was killed by Buckler while the ferret was about to slay Skipper Ruark Boldstream. Aggrim was a minor character, nothing else is known.
