with the ensuing slowdown in career advancement.
Massive rebuilding projects.
Political realignments and new polities.
Restarting merchant shipping, including new wormhole access rubric.
Population movement and immigration.

Combining and integrating military, including increases in ground forces
Bringing the TQ up in education, industry, healthcare etc.
Perhaps bring Selisian sytems into the fold, BTW it would be nice to know
Which systems were whose.
