Ryoshun Seido

Ryoshun's Grave was a temple built in a lost valley if the Northern Wall Mountains in honor of Ryoshun, the Tenth Kami.

Foundation
His brother Hantei commanded that Ryoshun's name be forgotten, so no mortal would sully his brother's name. He also commanded that only gods could enter the tomb until the Tenth Kami walked the earth once more. The grave site was located where the Badger Clan were eventually founded, and the clan was secretely tasked with guarding the grave of the tenth kami.

Hideo no Oni
The temple was used as a lair by Hideo no Oni. In 1166 the Keepers of the Books of Enlightenment and Ichiro warriors led by Ichiro Ryozan cornered adn killed the Oni. Asahina Hira deciphered a kanji with the language of the Kami, and recognized the temple as the tomb of Ryoshun, re-discovering it to Rokugan. Hira shortly after proved to be enlightened and became the Keeper of Void.
