[@Hawlin] Here's a rundown of the current factions: 

-Imperium: Ran by The God Emperor of Mankind. It recently lost to the alliance of Conquerors and is now rebuilding itself. The few followers present are going to Switzerland to find a specific terminal I believe. They're largely seen as the Good side, even if it seems a bit war mongering.
Most Arcadia-2 Refugees were aligned to this. 

-Goa'uld: Mostly NPC group that wants to conquer everything. They also think their leader is a God. They're currently in Venezuela. Pretty evil group but interesting nonetheless.

-Dark Outliners: My Group! Currently regrouping in Cyano Conablum's labs. After the timeskip some will go to Cybertron thanks to Grimlock's data stuff and likely clash with Ultron and pals. Other members will enter Arcadia-2 as they monopolized the only remains of the Terminal that led there. Also they're the Neutral side. 

-[s]Third Reich[/s] Sgt's new group: They've barely made an appearance. You should ask him about it if you're interested in a group that simply causes chaos because it's cool.
