Hey random idea. How about some players play as one of the warlords warriors, or even a warlord themselves, while others as the invaded people? You know make it a bit of a pvp ordeal. If not I'm totally okay with that.

Also for a bit of humor, what if all of the warlords claim that their the one that killed the hero, but no one has any proof so it's all a big argument/gloat fest.
