That's an interesting thought about the Silentium originating in the GFFA... I actually rather like it. It's always seemed too convenient that the Vong and the Silentium and the Abominor have all ended up migrating to the same galaxy. Sure, maybe the GFFA was the closest galaxy to the Vong galaxy, but... still a bit forced. The idea of a race from the GFFA invading the Vong's galaxy first is quite amusing... as it'd mean the Vong didn't start the war, they were actually just responding to the Abominor's ancestors from the GFFA trashing the Vong's galaxy first. EDIT: While I previously disliked the idea of the Celestials being a machine-oriented race, it's actually starting to grow on me, if in the GFFA's distant, distant past, there was a big war between races, all trying to "ascend", but through different ways. You've got whoever created the Silentium going the Ssi-ruuvi "entechment route", by merging with machines; and then you've got the Kathol/Cthul's ancestors who, if they're the same as They Who Dwell Beyond the Veil, tried "Force ghosting halfway" by becoming spirits. Two opposites - much like the Abominor and ancient Vong - battling it out in Machines vs Force.
