If you decide to let your character die in the Rp, its perfectly fine, because all that happens is that you end up here. The world of the dead is sort of a temporary place where those who have died in combat go. Depending on how many times you've been here, you stay for different amounts of time. Being here isn't all that bad though, in fact, it can be rather profitable. There are many wise people in the land of the dead. Some have valuable information. A few may be willing to teach you some rare jutsu. You can even interact with other players who have died. what you do with them is your choice, just remember, in the land of the dead, you never get tired, and even if a blade is driven through your chest, it doesn't leave a wound, so fighting is quite trivial.

How long do you have to stay? Well, here's the chart.

# of times killed____________real time days you must stay
_____1-3________________________________2
____ 4-6 ________________________________4
____6-10________________________________6
_____11+________________________________7

once your designated time is up, your next post must be of where you are going. It must be in YOUR village, or if you don't have one, anywhere you want.

Other then the dead, the only person you will ever deal with is the Nibi's Jinchuuriki. If She shows up here, she can force you to come to the living world with her to fight. Sucks, right? Well, she can only keep you for so long. As soon as she takes you out of the world of the dead, the amount of days you would be spending in the world of the dead is reset. Once it goes to zero, she can no longer force you to fight, and you are free again. Keep in mind, if you decide to attack or not listen to her, you're timer is reset again, and you are sent back here.
