The great Temple of Osano-Wo, the largest facility dedicated to the Fortune of Fire and Thunder, is located west of Ryoko Owari in the middle of the Plains of Thunder. The temple was founded at the end of the third century, two hundred years to the day after Hida Osano-Wo’s death, and it has survived ever since despite occasional attack by Shadowlands forces foolish enough to confront the Brothers of Thunder on their holy home ground. While the Order of Osano-Wo is originally an independent organization, over the centuries it is gradually welcomed into the fold as part of the larger Brotherhood of Shinsei. The monks of this order are widely known as the most militant and worldly of the Brotherhood sects, blending martial and spiritual training in a harsh but effective whole. There are few places in the Empire where one can learn more about the practical fighting arts.
The temple itself is constructed from limestone gathered from the surrounding plain, and looks as much like a fort as a temple. The roof is pierced with Kaiu-made lightning rods that flare in the frequent thunderstorms that wash over the area. In the front of the temple is a huge maze, also made of limestone, filled with hazards such as geysers and fields of sharp stones – this is a training ground for the monks, and visitors are kept out. However, the monks do welcome visitors and relish news from all places. The temple has large guest quarters and a special room is always kept ready for the Emerald Champion, who is viewed as blessed by Osano-Wo.
