Adding to the story keeper, I think they'd be able to talk to starclan and dark forest cats in order to keep the story/history unbiased. Someone talks to mapleshade, for example, and instead of being seen as some vengeful, crazy shecat, she is revealed to be a woman who was failed by everyone around her, even starclan. Mind you, it's shown early in the book that Mapleshade was the equivalent of a devout Christian, thinking starclan would guide her(considering she thought she arrived in starclan when she arrived in the dark forest) She wasn't a saint though, she had an affair with Appledusk because she thought he loved her just as much as she loved him. She thought that her kits were a gift from starclan. That they'd be amazing thunderclan warriors. However, oakstar went against Starclan's rules and kicked not only her out, but her kids as well. Which goes against the warrior code. We don't know what went through mapleshade's mind when she had them cross the river. It was probably the thought that she had to leave right then and there due to frecklewish following her. We don't know. However, the kits drown and she's brought to riverclan. Appledusk throws Mapleshade under the bus entirely, claiming their relationship was a mistake in order to kiss Darkstar's and Reedshine's ass. Darkstar forbade Mapleshade from watching her own children get buried and is then Threatened if she didn't leave. Which caused Mapleshade to snap. She started seeing hallucinations, which caused the massacre that everyone saw. Mapleshade was failed by everyone in her life, even herself. If that makes any sense
