Murderhobo Game Setting

So all this talk of murderhobos had me come up with a game setting...

---
The Land of Fallen Heroes

Alurence was a land blessed by the Allia, Goddess of Adventure as the home of heroes and adventurers. Young men and women, chosen by the Goddess would suddenly gain phenomenal abilities to wield blade and spell, and became champions of good and civilization, driving out monsters, defending villages on the frontier and ruling the population fairly and wisely.

Until they failed.

In the 113th invasion of Alurence, a horde of goblins, orcs and demons descended on the capital, defiled the temple to Allia and razed the city to the ground. Many Alurien heroes died repulsing the invasion, but those that survived... started to change. From stalwart defenders of the people they became selfish and cruel, barging into people's homes to steal their possessions, killing anyone who would defy them and wandering from place to place bringing death and robbery to the towns they once protected. New adventurers chosen by the Goddess suffer the same fate, their personalities changing, their selfishness ramped up while their restraint for violence toned down.

In this game, you play townsfolk who's just had about enough from these wandering, murdering ex-heroes. They are much stronger then you, but few. You must drive them away from your town, but do it cautiously, for doing a heroic deed attracts the attention of Allia, and her blessing is the last thing your town needs.
