Tamori

Agasha Tamori was the Agasha Daimyo who led the Agasha family during the Clan War and into the War of Spirits. During the War of Spirits he aided the armies of the Steel Chrysanthemum, and would later go on to become the Dark Oracle of Fire.

Family
Tamori had a wife, Agasha Tsutomu, and the couple had one daughter, Agasha Shaitung. Shaitung took up the position of daimyo after her father relinquished the post.

The Defection of the Agasha
Agasha Tamori is the shugenja for whom the Tamori family is named. He was the longtime daimyo of the Agasha family before the majority of the family left the Dragon for the Phoenix Clan. Refusing to leave and crushed by his family's betrayal, Tamori eventually left his position and his family name to wander Rokugan. (3E p. 22)

The Tainted Tamori
During the War of Spirits, Tamori sided with the forces of Hantei XVI. By this time, he was already a Tainted madman reviled by his clan. However, as a concession to the Steel Chrysanthemum at the end of the war, Emperor Toturi I was forced to rename the Agasha family still remaining with the Dragon Clan in honor of their Tainted ex-daimyo. Thus, the Tamori family was born. (3E p. 24)

Dragon-Phoenix War
After becoming the Dark Oracle of Fire during the War of Spirits, Tamori utilized a brewing hatred between leading Phoenix and Dragon to start a war between the two clans. The Dragon-Phoenix War raged for three years before the joint efforts of Tamori's daughter Shaitung and the Elemental Masters brought the Dark Oracle's manipulations into the light. Tamori was confronted by the Masters and his daughter and defeated, though not after killing two of the masters.
