Fishclan was formed by cats that were exiled from Rippleclan. They traveled with the cats that formed Rabbitclan, Mouseclan and Frogclan. They found prey rock before they found the territory.

They ended up going in the direction of a prey that they had in there old clan was. This led them all to there territory. They prey rock is where dead cats that died in the territories go. The clans go to it for advise whenever needed.

What Fishclan didn't know when they claimed the territory was that floods are extremely common there. Now they have to find ways to survive the floods or get the spirits in prey rock angry by leaving the territory.
