Well, OP expressed a desire for new quests, but there wasn't a specific place on the 1.9 boards yet, so here it is!
OP, you mentioned that the next storyline extension will be "Dark Age"; it would be helpful to have some sketch of what this means, so that one or more quests can be related directly to this idea. That subtitle invokes the idea of impending doom for someone: the Dom K'vash? return of the Ancients? renewed agression of the Coalition? or are the hostile Dom's now making widespread incursions into human space?
