Would Zed not've retitled the Kinkou monastery now that its his?
Just a haphazard thought that popped into my mind.
If the old teachings of the Monastery stood as a symbol to what Zed believes is impotence, and he generally wants nothing to do with Kusho's philosophy then why maintain the monastery's traditional name? Cut literally all ties, because its not like the Order of Shadows are trying to masquerade as the Kinkou.
