The veil is lifted.

A little late, but still: I completed it in 145 days and got the demoness badge. The game was quite balanced, but it became noticeably easier after freeing the adept. Interesting map structure; without hints, the process would have taken much longer. Many thanks to the author; I was starting to get out of the habit of playing Heroes, but here I got back into the atmosphere. I didn't find any serious errors, but I have a couple of questions:
1) I was surprised by the presence of voice acting for the heroes in the videos. How was it done? (The music drowns out the words quite a bit.)
2) How did you manage to make the hero disappear in the video?
