Final sprint.

I just downloaded the map, I'm starting to try it out, a question about the storyline: is this scenario the finale?

How many are there? I noticed one of them (seems like a succubus) - I destroyed it, nothing happened. After that, I decided that I need to kill everyone.

So, it turned out that the red one didn't appear for me. Does it appear immediately, or after a few days? If not immediately, then it might just not have had time to appear. I usually try to act very quickly when playing RedHeavenHero maps, without waiting for trouble. So, as soon as I received the task, I rushed to complete it without looking back.
