Bluestar believed that she made the right choice in appointing Mistyfoot as the heir of ThunderClan over Mossheart. Yet she is baffled when, seasons later, RiverClan breaks what is supposed to be a time of peace with a devastating fight for Sunningrocks. StarClan promises that fire will save their clan, but what Bluestar needs are more warriors to combat the evil lurking both inside and outside of their borders, not a vague prophecy that no cat can decipher. When a curious tom makes his way into the forest and finds himself in the middle of this war, discovering a merciless darkness held in the heart of a traitorous clanmate, he seems to be the only hope left for the fractured clan. A cross-posted matrilineal-decent AU for Warrior Cats.
