The End
Okay, Troll Doctor becomes a skeleton. You command him to fight the other trolls and he does. You roll some dice and do some damage and win the fight. You explore the dungeon and fight some monsters and get some treasure and there you go.
Outside, the world turns and decays. You go on a quest somewhere. You return home. Eventually, you die.
Somewhere, a new challenger approaches, and solves the campaign and wins.
