Battle of Tomorrow

The Battle of Tomorrow was fought in Yume-do between the One Tribe led by Kan'ok'ticheck and Tomorrow.

Traveling to Yume-do
The magic of the Tomorrow's Hourglass was used by Mak'irtch to allow almost the entire Nezumi race enter the realm of dreams and aid the Transcendents fight against Tomorrow.

Fighting Tomorrow
Kan'ok'ticheck led the forces of the One Tribe into Yume-do to protect the Nezumi Transcendents. The realm itself was in danger, and joined with the Trascendents to restabilize it. They succeed, but all the nezumi involved were trapped in Yume-do. For Rokugan the nezumi had ceased to exist.

Trapped in Yume-do
While they were successful in beating Tomorrow they were unable to return to their bodies, leaving no more than fifty Nezumi left alive in the world.
