After acouple of moons Birchstar had to choose a new deputy one day the day before he had to choose his deputy a cat named Ashclaw who seeked power threatened to kill Birchstars two daughters unless he became deputy.
Birchstar loving his two daughters agreed once he chose his deputy Sunclaw burst out with anger because that cat who threatened has only filled out some of the requirements when she has done all of them.
Sunclaw took over Shadowclan and became Sunstar but she did not go to the moonpool. Moonlight went into hiding inside a cave big enough for a clan she made that cave into moonclan territory.
