THE NEW ERA (1200-1248)
The Solomani Imperium recovers from the 1160s and reaches critical mass in Neworld Sector, to become a pocket empire on its own. It expands, sending ships to Terra and Home demanding they submit and join the Rule of Man as they call themselves. The (new) Terran Confederation refuses starting new conflicts. Home refuses, but is too far away.
In the 1248 books it is revealed that THE REASON Hivers created pocket empires like the Reformation Coalition is to slow down the Rule of Man. By having the RoM absorb too many worlds too quickly, they calculate and hope it will collapse under its own weight. Nicer states more amenable to the Hivers will remain, but this will take decades. Propoganda by Hiver traders turn the perception of RoM from entrenched military state to "ravening monsters". Individual RoM warships continually disappear, not due to Virus as much as Hiver warships. By 1248 it has taken over about 16 subsectors, 14 in Neworld sector, 2 in Aldeberan.
The Terran Confederation is on good terms with the Freedom League (formerly the Reformation Coalition) and the United Worlds in Diaspora Sector. The TC is doing slow and steady expansion like the RC did. They govern about 9 subsectors by 1248 centered on Terra. The Vegans are a willing part of the Confederation. It is not stated how supremecist the TC is other than it is far more moderate than the old Confederation was.
Both groups understood the threat of The Gods of Thunder represented and sent all the the ships they could to fight at both Battles of Gateway Station.
