RTF is a global modification that replaces all towns in the game.

I found this information a long time ago in the comments on the Heroes 7 website.
Quote:
Sareth did free the demons, but they didn't conquer the world; instead, they became, let's say, "aggressive neighbors" to the other races. With the arrival of the demons in Ashan, the cycles of eclipses ended, and the cycles of the Void began. In general, the demons became Ashan's enemy number 2, and the Order of the Void, Sandro, rose to a dominant position. I have no idea what the future holds for this. The information comes from Erwan's presentation on Ashan.

Official source or a recording of that presentation, please!!!

And in general, in this case, the demons should remain in the game, and such an ending is clearly nonsense! - the demons are finally freed, the most patient of Ashan's inhabitants rejoices! (I'm talking about the Overlord) and finally they can... just sit in Shi'o and forget about Ashan... - what, excuse me?! and the Order of the Void appeared again out of nowhere - it seems to me that whoever left that comment misunderstood something or made it up himself (or it's the "broken telephone" effect). To make such statements and base things on them, concrete, verified data from an official source are needed.
