Unknown kits, Unnamed she-cat
Shellheart's Grandfather is a tom with an unknown description.
In the Super Edition ArcEdit
- Shelltheart's Grandfather was Mapleshade's mate. Their love broke the warrior code, because Mapleshade was a ThunderClan cat and Shellheart's grandfather is a RiverClan cat.
- He is mentioned by Mapleshade, she tells Crookedstar that Shellheart's grandfather was her mate and they had kits. But when ThunderClan found out that Mapleshade had took a RiverClan mate, she was banished and the kits drowed when she attempted to take them to RiverClan. Shellheart's grandfather was unhappy with her that she let his kits drown.
