"Elhom IV has a cycle.  Hunters gather and form villages, villages form towns, dungeons spawn, cities form around the older and larger dungeons, with adventurer's guilds, and mage academies once there's a source of mana potions and enough paper for books.  The Demon Lord and Summoned Hero show up.  They fight.  If the Hero is stronger, kingdoms that are far enough away will keep enough of their cities to survive.  Otherwise the cycle starts over.  I'm not sure what skill a Summoned Hero uses when there's a mountain in her way and she feels like obliterating it instead of taking the long way around, but trying all of your new skills in order doesn't seem like such a great idea."
