Mmmm
-stuff about the plans of the Domain for the sector
-history (bits) about interesting but completely unknown(?) stuff like the unification (

) of the Domain. Unification? Does the domain really control 100% of human space, or did it before the collapse?
-(more) stuff about weapon and super tech development to fight unknown threats, even a crumb about possible contact with

or how the idea even came up (probes, long range observation, etc.) could be interesting
-Stuff about resources and ideas like post scarcity, how was the wealth divided across "realms"?
-How did Hegies and the sector react to other, unknown (?) to us (?) movements in the sector? History, stories about that?
-TTs commercial brands and history, tied right into intelligence gathering and (thus) not so tight and secure communications of the other factions which might potentially leak info via TT stuff, imagine all the shenanigans TT does or can do when 2 rival factions are planning to duke it out and TT and some "others" can listen to all the planning, scheming and battle operations, juicy, love me some scheming and chaos. A pea sized conflict could be blown up to an elephant if the right flames are fanned.
-history (bits) of Land battles for control on huge asteroids, planetoids and planets and stations
-The Daily Pather - Printworks for the Zealots! So, are Pathers into digital newspapers? Can we meet the chief editor?
E: More Luddite stuff, like the battle of traditional weavers against the more futuristic stuff, but the evil corporations reshape the (habitable) landscape and the water mill powering the workshop stops working because the river is no more...

How's the internet in the sector? Are there parcel and postal services?
Luddites, spacers and radiation... What's the plan about the more "unstable" stars in the core and sector? Or, what were the plans...
