I just think theSpaceTexan knows a lot more about these UA's. Funny how he knew where to find them (gave us all a good riddle that seemed to pan out) then the next day he makes a bee-line to SAG A (without the artefact, as toxic) makes me think we're supposed to find the artefacts origin using SAG A as the point of reference. It's a long trip to make unless your fairly sure your on to something.
Aye, you guys are now a lot closer to the truth. However, are you willing to venture into the darkness and discover the truth hidden within the truth?
If so, then go out there brave Adventurers and find what secrets are still left to be told...
