There's this planet named Riot, and the CG currently controls it and uses it as a shipping yard for trade and for the war effort. The GRE wants this planet for its rich fuel, so it plants special operation forces to take it from the CG.
The CG leave before they can discover the fuel source under ground, and the GRE moves onto the planet. Crimson Guard finds out about the fuel, and teams up with some of the GRE's allies.
All in all, the CG wants the fuel, the GRE won't let them have the fuel and resources, the CG teams up with the allies of the GRE, and the GRE doesn't like it. War is imminent. Permalink
