While I go through the Galactic War as a Progenitor Commander, I'll be posting the planet descriptions here. They contain TONS of lore on the Progenitors. If you don't want your GW spoiled, DO NOT continue to read this thread. - Progenitors knew discrimination. - They also had things like rich/poor. - The origin of our solar satellites, probably. - Hover cars. - Progenitor-Commander War. - It is implied that the Commanders rebelled against the Progenitors. (Machine Liberation Army) - Century War. Against who? Not against the machines, it seems. Seems to have happend before the Pro-Com War. - Progenitor High Command seems to be the group that controls the Progenitor Army. - General Assembly? - There were humans. They lived together with the machines in the Progenitor Coalition. - Ooh Area 51-ish. - Operation Kadota seems to be the name of whatever the Progenitors did to end the Pro-Com War. More to come.

I did a look over the lore shown from the planet's descriptions, and compiled it into a little summary. It's a long read, and is missing hole, depth and some context. But give's a good overview of the backstory.
