''Dark Age'', huh? Sounds to me more like an all-out war in every corner of the galaxy. Destroyed jumpgates, debris fields as remnants from huge battles... As for quests - Sabotage enemy shipyard installations, hit-and-run ops on supply depots, intel gathering, rescue ops of important political & military personell (the quick in-and-out kind). Humans are a young & small race, so they`re perfect for such Guerilla warfare.
