Oh christ....... just help the guy!
Tell me (by PM) where and when and I or a friend of mine will visit your city, kill the marauders......... only when the army leaves bring your hero to life. Your city will be free to play the game as normal.
Happy Gaming.
2 Things might help...
1: Exploring your well will bring Marauders, and you will need a big army(in newbe terms) to kill them
2: Always keep 1 Troop(any type) in your city when you go on a campain. This will stop marauders spawning in your city while your out.
