Warrior Cats Midnight's Revenge

NightKit is a dark grey-blue kit. Everyone ignores her and sometimes even tries to kill her. She doesn't understand why, but no one liked her. Not even her family.
She ran out to the forest, seeking revenge. She grew cold and bloodthirsty, then ran into 'BloodClan'.
BloodClan liked her fierce, aggressive and bloodthirsty attitude. They accepted her in, and she fought well. The 'clan' seemed to actually adore her, some fell in love. She was the only female in BloodClan, and Scourge loved her deeply, liking her even more day by day, she was not known as NightKit, but Midnight.
(This is my own version of BloodClan, Midnight is the only female, the cats can only die of sickness or old age, Scourge is secretly immortal)
