#WarriorCat Oakstar had banished her, knowing she and her kits cant go to twoleg place, as he raided there often, their only choice was Riverclan, and was denied... she was so angry, her kits drowned too, as it was flood season, Oakstar knew that. Poor mama Mapleshade became a killer, thanks to Oakstar, and the other cats. she was ultimately killed by Perchpaw.
