- -Longpaw to Sepia, The Heir of Mistmantle
Longpaw and Sepia aren't seen to interact much over the course of the series, but it is indicated that the siblings are fairly close. Longpaw joined the party in readiness to help Sepia when she attempted to rescue Catkin, and he congratulated her on her success after pulling her from the water. Apple also expressed sympathy for Longpaw in particular when Sepia was swept out to sea by the Rage Tide.
