Wes, you want a megastructure. It's the only megastructure of the like in Yamatai. Do you want it to be represented by the present wiki article? Something big that's essentially a footnote in our wiki?
You need art for this.
I also want to see effort and even roleplay perhaps invested in the idea of it forming up and being invested it. I'm not as attached to my plans in the Bard Cluster (barely at all anymore save for Kotori's senate duties) so there's nothing to trample over anymore, but I kind of want to see you make it worth it.
What is this place going to mean for us plots? Why is it cool for us GMs to showcase it? What roleplay opportunities might it bring?
You say "I would like to get this approved by the end of the year". I say "I would like you to make this look alive by the end of the year". It might be even better if you showcased it in your own plot.
Crazy idea: this region has always been influenced with a rocky history (the 3rd expeditionary fleet and everything that came from that) and the Empire wants to reclaim the area, consolidate it, and then push for exploration toward that vector. Hanako gets promoted Taisho, gets the job of rebuilding the 3XF (and doing it right this time around) and there you go with a new font for roleplaying opportunities.
If you want something big like this, I'm of the mind that you should try to both own the concept and embrace it. The alternative is a throwaway structure that will ultimately mean little if you don't give it meaning.
