How come there are more bandits and necromancers than regular people ?
Because you really don't want to kill the regulars in the game. They are the ones who give you quests and rewards and do business with you. So, you need something to play with when there are no Dragons, or Wolves, or Trolls, or Tigers, or Crabs, or Bears, or Giants, or Wraiths, or Drauger, or Skeletons, or Horkers or something else is not around.
