As I am absent for some time (partly) I have sacrificed the day to give you a bit more motivation to become strong (=Sannin in title).
I created Hoshi Gakure as a place where Sannin or above ranked shinobi gather (there are no player characters from there, so these are the only ones who can pass the rift without help from the inside).
I have added some special features, the limitation of the people there also give you the opportunity to be among other veterans.
(like secret rooms for Jounin).
I want to (spoiler) some things:
-You can build castles there... they are vast, and can hold quite some people, but are expensive. (until now I have not made more rooms for the dwellings in general, time issue though and a brand new module -> testing, also furniture is not there).
-You can switch your gender (for a price)
-You can buy something to escape Shinigami before the time ... that's all I want to say.
and also some other features.
