Clan names still need to be figured out. Perhaps one clan lives closer on the mountain side but with a small area of forest. So they could be Mountainclan, Rockclan, Boulderclan, or something along those lines? The other could be more forest oriented with a dense forest that they live in. So maybe after a tree? Oakclan, Pineclan? I'm not sure if the thunderpath should split the territories though. I feel like it should just be on the edge of both but maybe cutting them off from the moonpool/moonstone place.

As for the moonpool/moonstone, maybe small cave with crystals of some sorts like where the moonstone was in the books?

We would also need to figure out a gather place. Some neutral land between the two territories.
