overall, everything turned out to be much simpler. I started the first mission again. I captured the castle, killed the enemy, and started building up my army and constructing a guild of magic. I built it up to level 5, then went around and collected all the runes that give stat boosts. The second mission was easier this time. On the second week, a random Necropolis hero showed up, but he wasn't a threat. I built up my army, headed to the port, and started slowly capturing castles. At the same time, I was also leveling up another hero on weaker heroes, and I made my way to Mythgard. Taking it wasn't difficult. (version 1.50)
