Battle for the Last Tower

The Battle for the Last Tower took place in 1159. It was an attempt by the Crab Clan to take back the fifth tower of the Kaiu Kabe. Hida Kuon and the rest of the Crab armies fought alongside the Unicorn Clan Baraunghar army commanded by Iuchi Lixue.

The Crab shugenja summoned the aid of Hida, Yakamo, Kisada, and Osano-Wo. Jade rain fell from the skies, strengthening the Crab, and striking down the Horde. But when they reached the Tower itself, Fear awaited. Kuroda, now the Onisu Kyofu called forth the Horde's ally; as Fu Leng continued his War in Heaven, he blacked out the skies over the Wall, and cursed the tower itself, suffusing it with raw Taint. 

The Crab won the battle, but the tower was irrevocably lost to the Shadowlands. Kaiu Umasu ordered the wall to be torn from the tower and moved farther back at that section.
