I have a feeling that we're eventually going to find out in future novels who the Celestials (or the Architects) really were and what happened to them. This is one of the last great mysteries yet to be revealed about the Star Wars universe. They created Corellia, the Maw Cluster, Centerpoint Station and more. But what happened to them? After long thought, I have come up with eleven different scenarios that I think encompass all the possibilities. Any other potential solutions can probably be summed up in one of the following statements. So whenever the mystery is finally revealed, I believe that it will be one of the following 11 answers: 1. They ?ascended? to a higher level, left the universe as we know it and took most of their technology and achievements with them. 2. They gradually ?devolved? into everyday humans (or some other species) and forgot their past over the eons. (doesn?t explain the disappearance of their infrastructure) 3. They were wiped out by another, powerful alien foe. (what happened to the foe?) 4. They were killed by a great plague of some sort. (again, doesn?t explain lack of structures) 5. They destroyed themselves and their infrastructure in some kind of civil war. 6. They were basically good, and were destroyed by some terrible evil that still threatens the entire universe. 7. They were evil, and were destroyed by a combined coalition of other sentient races. 8. They were basically good, and went into hibernation and hid their technology to face some greater threat in the future. 9. They were evil, and went into hibernation to come out and destroy everything built during their absence (ala Mass Effect, or the Shadows/Vorlons from B5). 10. They went into hibernation simply out of boredom, finding no more challenge, mystery, or point to the universe? waiting until the end. 11. They never existed at all. What is attributed to the Celestials was actually the actions of numerous other ancient races and/or beings, which have been forgotten through the ages, and the legend of the Celestials materialized out of speculation and myth. Any thoughts? If you have any other valid possibilities, please feel free to post them below.
