Heroes of Might & Magic III: Horn of the Abyss

Oh, sorry, I underestimated the effort... It's incredibly difficult and time-consuming to create an ERM map! But I'll show it when it's ready. What I'm most interested in is whether you already have campaigns with a storyline. It's one thing to design the game, objects, and castles, and another to somehow organize everything together. I personally liked the campaigns from AB more than from WOG (they're even unfinished there, although I felt how difficult it is to work with ERM)). If you want to present new heroes in all their glory, you need a good storyline!
P.S. I don't know where to find one myself.
