Joining Tetsumura
The Village of Tetsumura is closed to all without an invite, and joining the village itself comes with its own specific set of rules. If you are a civilian who is moving to the Land of Iron you will be expected to learn the land's customs and traditions, as well as its history, so that you may properly adhere to the Bushido Code and understand why it exists as it does. This will amount to doing a solo thread where you are educated on these things, which will be checked by the Shogun or one of their guards.
In order for a Shinobi to join the village, they will go through the same steps as the Civilians. They will then be given a task by the Shogun in which they will be accompanied by a Samurai of the village. This task will test their knowledge and dedication to the Bushido Code, and will be done to show that they have released their former unwelcome Shinobi traits. They will then be forced to renounce their heritage as a Shinobi, and will go through a cleansing ritual that will purge the influence of the shinobi from them, and they will then be "reborn" as Samurai. They will be judged according to their class, for higher class shinobi are considered to further have been tainted by their influences.
If you wish to join the village and the Samurai, you must first write a letter stating your intent to travel to the village, and you will need to meet with either the Shogun or one of his guards in order to begin the process.
