With in the highly industrialized Rain Village, there is a certain area located beside the Ninja Academy where Shinobi are welcome to carry out their battles and training. You'll find that the Fields have different terrain in certain areas: In the North, you will find the Lake area; South is the Earth area; East is the Forest area; and the West is the Plain area. This area does not have many rules, though any offense severe enough will have a single warning and could result in exile (ban). The one and absolute rule is that no Rain Shinobi can take the life of a fellow Rain Shinobi, or any other Village ninja, unless unavoidable, given orders, or the Shinobi has committed a heavy crime. Thank you.
