I've just recently begun reading the Warriors series. I am only on the second book, but it has made me want to roleplay in the world already. 

I was hoping for something relatively simple. There are four clans of cats: Thunderclan, Riverclan, Windclan and Shadowclan, all of whom keep their borders protected from the other clans, as well as other terrors. Each clan flourishes with new kits born each year, and young apprentices training to become mighty Warriors, while starclan looks from overhead. 

We are from Riverclan! We are strong and we brave the rushing waters of the river where no other cat would dare and reap the rewards of the fish within. Starclan has given us a strong and wise leader, and brave warriors unlike any other. Be proud of your clan and fight for their honor, young Apprentices. 

The idea is you play as a member of Riverclan, a cat. Anything from an apprentice to deputy (there is only one). I was playing with the idea of everybody starting as apprentices and working their way up together and then letting everyone take on the duties of NPCing the rest, but I'm open to open world building as well. 

Would anybody else be interested in this idea?
