I don't remember what map we were playing.

I can't remember right now, but I'll try to recall tomorrow or the day after and I'll definitely tell you:smile33:.

So, I looked it up and remembered, as promised:smile33:. It turns out it's a standard map from the "Whirlwinds" set:D. It's called "7 Steps (or Stages?) to Glory," and the battle took place approximately in the center of the map, where there were Draki (176 of them) led by a level 40 hero (Chaotic, and no magic affects him!).
Some kind of bridge is being guarded:smile07:.
