Find the topic that was created on what village you will start off with and not the one that recently made today/yesterday and read @Rory post on creating Sound and not knowing about Kumo. Hmm maybe I read wrong though I believe I did see that somewhere and I am trying to find it. But for now as I said in another post, It was as said earlier a giant laboratory composed of various hideouts and bases. It can be best compared to a speakeasy. But overall it was a front as a village and Nin Online is set years ahead of the actual story so whether it was a real village or not in the Naruto world, it CAN be a real village in game. There isn't much images on Oto for one reason being there's not much to show xP but this is where creativity comes in, use all you can from show/manga then put together the rest.
