Traitor's Grove Dagger

Traitor's Grove Daggers were curved daggers used by a shugenja to seal a Scorpion traitor's spirit in the heart of a tree in Traitor's Grove. They were kept locked in Kyuden Bayushi until they were needed. A bound soul might not return from the dead by any means unless the tree that imprisoned his spirit was killed. This process also made the tree extremely long-lived.
