If it makes you feel any better, I don't think most people, monstrous race, dark elf, or otherwise, truly know/knew what's going on. As far as dark elf stuff going on, unless you happen to be part of that particular city and have knowledge of what they've planned, you're likely going to be just as in the dark as everyone else. In the recent cases that I think you're referring to, I believe they have been run as semi-open cdq's with avenues for outsiders to get involved. You are more than welcome to get involved in your own way as everyone else has, including some of the darker dregs of society.
If there happens to be a series that comes up in which the darker side of Layo would have some extra knowledge, however, I agree that those darker PC's should have some sort of knowledge of what's going on. However, which faction isn't always known, so you'll still need to have your own alliances and networks in order to gain the information, or at least PM or somehow contact the GM or GMs running the quest. I know that we've tried, recently, to put rumors up where it is applicable, but in some cases even those rumors were not applicable because people didn't even know what was going on until quest time.
I hope that helps and clears things up a bit. No one is being excluded from these quests. However, if you aren't involved with the right people, as always, access to information is limited. Definitely do followups if you/your character feel so inclined. Cheers!
