In Mapleshade's Vengeance, it explores more about how Mapleshade got into the Dark Forest. Three of her kits(Larchkit, Petalkit, Patchkit) drowned, and she saw them in her dreams yowling. She decided to kill Ravenwing, the medicine cat, because he was the one who told ThunderClan that Appledusk was her mate and caused her exile and the kits' deaths. After she had killed Ravenwing, Larchkit's yowling had been silenced, so she figured out that she needed to avenge her kits three times because there were three kits. The second cat she kills is Frecklewish, the cat who had also wanted her exile because Appledusk had accidentally caused her brother Birchface's death in the river. Frecklewish was bitten by a snake, actually, and Mapleshade didn't make any move to save her. The third cat she kills is Appledusk when he is defending an apprentice because he turned her away and blamed her for the kits' deaths. Those three murders probably landed her in the Dark Forest, because it is the most severe breaking of the warrior code, though she broke it even before that, but that was for love. ~Blossomfur
It doesn't tell what she did to go to the Dark Forest. Sure she had kits with a cat from another clan but so did Bluestar and Silverstream and they both went to Starclan. The answer can't be that she tricked Crookedstar (Stormkit/Crookedkit/Crookedjaw)because she was already in the Dark Forest at that time and never was in Starclan. So it remains a mystery why she's in the Dark Forest.
When Mapleshade was still living, she had a forbidden relationship with a RiverClan tom (she was from ThunderClan) She ended up having the unknown tom's kits, became exiled from ThunderClan, and carried her kits to RiverClan, in hopes that they could live there. Sadly, her kits drowned while she tried to cross the river seperating the two clans. When she arrived in RiverClan, Mapleshade was blamed by her mate for the death of her kits. Now exiled from RiverClan, she was forced to become a loner, and grew a strong hatred and jealousy toward her former mate's kin with another she-cat. I don't see how that's truly evil, but she ended up in the Dark Forest. In my opinion, she became more evil after death. ❄ Blizzardpelt ❄Freezing in the Summer! 00:48, March 27, 2012 (UTC)
