1st inter-portal tournament of HMM3-OFF: "Air Magic"

You guys aren't very active...

I thought everything was supposed to be submitted on the last day... oh well, I'll send it today.

Huge thanks to the map creator.
Regarding the map:

Hell on the map is clearly cut off from the outside world by various border guards. It's obvious that there used to be another beautiful castle there a long time ago, and over time, only one garrison remained. Hell itself is divided by a mountain range into two parts - eastern and western. And there's also a hidden stash of red mercury disguised as a dwelling for the local inhabitants.

This reminds me of something, although maybe I've become too sensitive?
