Imperial Herald #14, Legend of the Five Rings History
Imperial Edition
The clans warred actively. The Crab, having seen how the Scorpion seized Otosan Uchi and watched the Empire begin to fragment, realized that they now had a chance to take the throne for themselves. After defending the Empire for a thousand years against the fearsome Shadowlands, they now entered into negotiations.
Kuni Yori induced the Crab Yakamo to lend his name to a fearsome oni, which manifested itself in the material world and commenced an extensive battle of wills with Yakamo for control of Yakamo's name.
For reasons not understood even by the Dragon generals, Togashi Yokuni, the Dragon daimyo, retained Toturi, the disgraced ronin, to lead their army at Beiden Pass. Among the dragon troops was Mirumoto Hitomi, young scion of the Mirumoto family. Hitomi had many strong passions, and her greatest hatred was for the hero of the Crab Clan, Hida Yakamo, who killed her beloved older brother years earlier in a duel of honor. She claimed Yakamo cheated, which he, of course, denied.
Hida Yakamo had already lost a hand in a duel with Hitomi. Kuni Yori, a powerful Crab Clan shugenja, grafted a hideous claw-like appendage to Yakamo to replace his missing hand, using a terrible ritual that neither would discuss.
Stepping out of the mists of legend and rumor, a strange group of humanoid serpent-creatures known as the naga reappeared in Rokugan, though sightings of the creatures were few and far between. Toturi sent Mirumoto Daini to investigate these sightings.
