War of Dark Fire

The War of Dark Fire was a conflict started in the winter of 1170 by Dark Oracle of Fire Tamori Chosai when he sent his minions, including the Yobanjin, to invade Rokugan.

Initial Attacks
The initial attacks were discovered by the Fourth Imperial Legion led by Hida Tonoji, who were sent to investigate the Northern Towers of Flame but found them destroyed.

Thereafter the Yobanjin invaded Unicorn territory and overran the Badger Clan, also destroying the Mountain Wind Tribe, who had been peaceful allies of the Badger and Crane. The army continued to wreak havoc, even damaging the High House of Light sufficiently that it had to be put to the torch by order of Mirumoto Kei.
