620 A.S – War between Rheinland and the GMG erupts over ???
Rheinland had the largest military fleet in Sirius and was paying GMG through the nose to fuel it. Kruger pushed for an invasion of the Sigmas to take the fuel fields for Rheinland, Daumann approved because of the shipbuilding contracts it would generate. Condense as you please.
Other GMG related events can be found in the timeline I put together for the faction writeup. Feel free to include or exclude as much or little as see fit.
