Awakening of Evil

Thanks for the answers). I found a town, but it has almost no resources. I think I'll try to defeat the Chaos mentor for luck; he had a skill that granted resources for killing creatures, and since there are legions of them...
P.S. I finally killed that unit, losing all 10 Shadow Lords and 8 Beasts. The mummies chased the Beasts for about 20 minutes, but since they were wearing boots with +1 speed, they couldn't catch up.
