Demon invasion.

I always killed the demons with cavalry on the first turn, and everything was summoned. The orcs started attacking from the second week. When I was killing the brown hero, I already encountered him at sea with a high risk, and the purple hero was attacking my castle with a couple of heroes at that time. And astral gates should be forbidden on the map... it's a pity that Master hasn't been seen on the forum for a while; he could clarify.
