Four saints, especially the sword saint, seem sussy as hell. The four rulers because of their ancestors? Possessing secret knowledge- And they don't seem concerned that pages are torn out of their secret knowledge book? But they still act like they know everything. Can't even show their faces in their secret meeting room?! Excuse me, but you guys are a cult!
INteresting that the Great Sage is missing. If I follow the tropes, they probably discovered some BS and went into hiding from the other saints. That means they're out there, somewhere. Possibly as a character we've already met!
