Concerning Villages.
Each Village is limited to.
1. 2 DNA Sects
2. 3 Secret Sects
3. A Max of one Sanin atm, A max of 3 jounin atm. The chunin number will fluctuate and Genin are unlimited.
4. One Village can specialise in one aspect of technology. For example Iwa no shi may specialise in subterranean technology such as drills and tunnel making, Kiri no Shi may specialise in aquatic technology.
5. A village is also limited to having at most two Jinjuriki. Their is a reason for this as I dont want one village housing all the bijuu it isnt fair. Although it is perfectly acceptable to attack another village to try and steal their bijuu if you just have one or none at all. In this instance the Jinjuriki will die when the bijuu is removed.
