If I remember my lore correctly, didn't Centerpoint Station have the ability to move planets, or something of the nature?
I checked Wookieepedia, and it does. Maybe I'll use that.
During which timeline are you placing Tython, Centerpoint station wasn't created until, well, much later in the Star Wars universe . There could be an unexplored region in the Deep core, that could work.
Legacy Era, specifically 107 ABY, but I stated that Tython was moved not long before Centerpoint was destroyed.
Good idea, that could work pretty well. You could say it was like a first experimental test for Centerpoint, just an idea.
