Tasogare kan

Background
During, the waring era before the foundation of the Gotei 13 Mushoku Kaigan of the Panteon went to Genryūsai Shigekuni Yamamoto. He proposed an allied nations organization between the Soul Society's Shinigami and the other spiritual beings like the Senjungami. He thought that these treaties for the spiritual nations that were allied with the Soul King would be more productive, than just having them unorganizated. Yamamota after a year of talk and meetings with the Shushin of the Panteon, agreed to this. Mushoku had created the Tasogare kan as a place where such meetings could take place.

The manison itself looks more like an English manison. The walk path is covered with trees, on each side outside of the walk path. The manison is able to house several hundred beings.

Abilites & Powers
The Tasogare kan was created by Mushoku Kaigan. As this is a neutral place he placed many protections on the manison.

Defensive Powers: The first and foremost if that the Tasogare kan, while inside of the Soul Society cannot be found so easy. Mushoku used his powers to distort space around the manison once built. Now if one knows how to get there its possible to go there from any location. The only two known methods is with one of special key can make a portal open that leads to the dimenison. The second is with a spell known as Honebashi (骨橋, bone bridge). The spell can be cast by anyone and by a number of species include Shinigami and Senjungami. Once casts teleports them to the manison. The manison also has several other protections.
 * A Zanpakutō cannot be released in the manison. This doesn't apply to the training hall.
 * Fighting is possible in the mansion. However, anyone killed inside will be revived. This is part of the training hall inside off the manison.
 * It's not possible to break in. There is a spell called Kotobatoguchi (ことば戸口, word doorway). This a spell that unless Mushoku wishes to or unless you don't know the password to get into. The manison will throw you outside of the manison.
