The Lian System Incident occurs with a first contact in the far coreward of human occupied space; the Sinopact first contact with the Shil’vati goes poorly. For whatever reason the scouting elements of the Imperium are determined to have hostile intent and shots are fired. The Imperial Navy reacts with staged assets from nearby systems, beginning their conquest of the Sinopact and what they assume is humanity as a whole.

Imperial Naval forces begin a general offensive across the Sinopact ‘coreward’ frontier with eight thousand plus vessels.

Sinopact makes the Coalition of Progressive People’s Systems aware of the situation, intelligence leaks also inform the members of the Solar Confederation (CONFED) of the rapidly moving alien incursion into Sinopact Space.

The United American Systems and European Cooperative Community begin a general mobilization of naval assets.

45% of Sinopact holdings have fallen under the Imperium’s control, 3.2 billion humans have died so far in this conflict with Sinopact military forces taking murderous losses. Sinopact leadership and assets that are mobile begin to retreat toward the KSPN border.

60% of Sinopact holdings have fallen, retreating forces begin to ‘scuttle’ habitable worlds with salted very large yield fusion devices whether they’ve been fully evacuated or not. 4.2 Billion human deaths have occurred.
