Inferno – “A fitting image for you” [Campaign 5, Mission 2]

Well, I managed to defeat the Lady in the human castle around week 2. Accordingly, I started taking the Necropolis around that time as well. Meanwhile, my main hero went to capture the upper fortress, and the secondary hero defended the castle.

I'm a bit fuzzy on the details, but how many Necropolis castles are there right after the human castle on the vertical path leading downwards? One or two? I think there's one, and then a path between the mountains, and after that, there are castles and fortresses in different directions.
