First off, is this still open?
Second question. If each land has a beast, whose associated with that type of chakra, would that mean that those who use said chakra, would have attributes that were similar to the beast? It doesn't necessarily meant they'll get special techniques or anything like that, but maybe just designs over their faces, or something noticeable. If this is the case, then everyone around would be able to see whose using this world's version of "chakra," and would be able to ostracize them much easier.
