Book of the Void

The Book of Void contains the ancient wisdom of Shinsei. It was found in a small alcove within the tomb Ryoshun by Asahina Hira.

Enlightenment Challenge
The challenge for the Book of Void was

"The sage who could perform a task greater than the other four things combined. ..."

The four Keepers of the Books of Enlightenment were sent to Badger Clan lands for an unknown purpose. There they discovered that the Badger Clan faced destruction from within and without. An Imperial delegate, Miya Tsurugi had been dispatched to judge whether the Badger Clan deserved it's Minor Clan status. Meanwhile, the Badger Clan's fearsome enemy, Hideo no Oni was once again ravaging the countryside.

The Keepers were able to help the Badger Clan defeat the Oni but that was not enough to save the Minor Clan from Tsurugi's judgement. It was the blind Shugenja Asahina Hira who discovered that the temple that Hideo no Oni had taken over was actually the tomb of Ryoshun, the Tenth Kami.

Hira realized that the Badger Clan's purpose was really to guard the tomb, and thus their status was divinely mandated. Tsurugi had no choice but to agree, granting the Badger Clan the right to carry on as a Minor Clan. Tsurugi went further and promised to allocate extra funds be sent to aid the Badger Clan to help restore it to its former glory. Several other clan delegates were present and promised their support. The Crane Clan promised to pay the Badger's taxes in full for that year, while the Crab Clan promised to send some Kaiu Engineers to build a wall to fortify the tomb as well as creating rice fields that will survive in the harsh weather of the mountains. Hira speculated that the other clans would most likely send aid as well.

For securing the future of the Badger Clan and ensuring that their divine mission was upheld when none of the other four Keepers could, Asahina Hira completed the challenge and became the Keeper of the Void.
