Have to agree with the commenter last chapter. If these antagonists where half as capable as they appeared to be, their goals would have already been completed.
the local governments feel weak, the faculty of the academy seem more self-destructive then knowledgeable, and the adventurers guild seems utterly subverted.
About the only other person on the planet that seems to be able to stand up to the "bad guys" is a single priest from the local religion.
So are the villains of these piece just so inept that they can't even accomplish their goals despite having all the power and resources needed to do so?
Wasn't it stated that the church is actually way more powerful than it seems on the surface? It's not just a single priest but an entire hidden branch that is at that level.
Also, I think the implication from everything we've seen so far is that all the evil organizations are held back by their own members constantly backstabbing, killing, sacrificing, cursing, etc. each other. The lab clearly only functions at the highest level because the mental corruption curse of the book of ethos prevents upper level members from harming each other.
I personally think that the book of ethos was originally meant to be used by people who recognized the threat of the true dragons, and since they can't really be permanently destroyed, that would ensure their loyalty to the cause of saving the world from true dragons so they wouldn't misuse the magic in the book, like a sworn oath backed up with magic. The evil organizations all clearly started as true dragon countermeasure organizations, but somewhere along the way "make hard but necessary sacrifices" turned into "every sacrifice we make is justified" and it's now spiraled out of control into a bunch of narcissists, sadists, and psychopaths killing indiscriminately, even among themselves.
