Oh, what a schemer, he didn't say anything at all. I hope it won't be too painful to realize that the scenarios were made aimlessly? Well, I'm just kidding... Who is the main villain? Shouldn't we, as creators, know all of this? Otherwise, you might inadvertently create a problem that's hard to solve.

Well, I'm just building up the suspense. Moreover, the interest will lie in the fact that you'll want to play through the campaign again (you'll understand this after playing it the first time, and then the second time, i.e., the last scenario).
As for the intrigue, I've taken this into account, considering that you are the creators.
I'll just say that such a "twist" hasn't been tried before in the Heroes series, and if the test is successful... well, we'll see. I'll try to quickly refine your and Optimalov's scenario and submit the final map for your consideration.
