Daidoji Yukan-se

Ronin
The Valiand Daidoji Tower is held by ronin who were once Crane, at least their ancestors were. The tower was claimed by the Crane after a victory over the Scorpion Clan, but some secret vice caused the samurai here to be cast out from the Crane. Their descendants struggle to rejoin the Crane, but with no success. (3E p. 301)
