When you lay your cat to sleep each night, there is a 1 in 4000 chance to wake up in StarClan. Because of this, there's only been a couple of people who have seen StarClan before. You won't be able to do anything in StarClan except for talking to a cat near a lake.
When talking to the cat, they will usually say, "Hello ______. I really like this lake. You will now wake up at Fourtrees." Right after, you wake up at Fourtrees instead of being in your Clan's camp. (Dens)
