The Blue Chrysanthemum Dojo was a secondary dojo of the Emerald Magistrates in the Doji lands (the primary dojo being at the Castle of the Emerald Champion). It was built shortly after the Battle of Stolen Graves by the reigning Emerald Champion, who was a Crane. The Blue Chrysanthemum dojo itself was divided between two locations: one in the Crane lands; and the other near Otosan Uchi, which was attended mostly by non-Crane students. The Otosan Uchi branch's fate is unknown after Daigotsu's attack on the Imperial Capital.
