Warrior Cats Fanfic: The banished clans

In an alternate universe, the four clans of the forest are doing well.
Until, a sudden prophecy is awoken that will shake the lives of the clans forever.

Metalclan, a group of cats who live on the mountains are suddenly banished from the mountains alongside Wishclan and Blossomclan, due to a prophecy from Sparrowcore, the medicine cat of Moonclan, that he believes symbolises that only Moonclan must remain. The leader of Moonclan, Crescentstar, seems almost definite that what she's doing is right, but after the moon is covered, she knows somethings wrong.
