Before the recent lore, I always thought Zed was in a dark temple (with a dark and mysterious past) with like a 1,000 ninjas hailing him while he drunk some sake. Now they are more like outcasts with Zed as their leader on a journey. It sort of gives more depth in the characters around Zed rather and gives clear explanation to his leadership and experience.
There was this one instance in a tavern that one of his followers **did not know the concept of money** because he was raised as a warrior from childhood and made threats to the bartender stuff for free food. Zed calmly orders the man to be set free. It does gives us insight the Kinkou order was one messed up organization.
