@Crusader Lord1. Currently active are:
MWBOS - The Midwest Brotherhood of Steel, the powerhouse of the midwest of america. Lead by Simon Barnaky, who has his brain placed into an ancient machine, it is currently locked in an apocalyptic war with the Cult
The Legion - Losing Hoover Dam, but winning the war with help of the MWBoS, the Legion is now lead by Lucius, who is currently joining the war against the Cult. They also won a second, smaller war against the NCR, that the whole of America agrees on, was pretty damn stupid to begin with.
The Children of Atom - Taking over the power-vacum left behind by the cult in the Capital Wasteland, they Children of Atom became quite a power to be reconed with in the north of the US.
The Institute - Winning the war for the commonwealth and with a 200 year old former ice-cube in charge, the Institute remains a wildcard in the conflict
New Vegas - Remaining independent and heavily profitable,
Mr.House has restored the city of Sin to ancient glory, uncaring of the costs. He remains a power broker in the West and an economical Juggernaut
The Commonwealth of Pennsylvania - A proper christan nation, the Commonwealth was a regional power, before finally joining the conflict against the cult. Also containing badass pirate hunters
Free Texan States - Dont mess with Texas...duh!
Western Brotherhood of Steel - Far to the west, the WBoS is not quite content with the current status and the looming threat of becoming a Junior partner to the MWBoS, now sporting territorial ambitions of its own
Free State of Franklin - We dont talk about the crazy hill people
80s - Remnants of the old great tribes along the I80, divided and beaten by the NCR. Now, with a new warchief trying to unit them to win a future for his people
EcBoS: Shattered remnats of Lyons Brotherhood, now lead by a very pissed of Sarah Lyons
The Cult - Stars bleed for Ug-qualtoth. Embrace the monolith!
NPCs:
Key Republic: Trader republic that currently has a pretty bad civil war
Detroit: Powerhouse in the east, that was infiltrated by the cult and now is fighting for its surivial
NCR: Still greatest power in the US, but heavily beaten down due to an insanely dumb war. Also had a civil conflict that futher saw it decline. May or may not be eclipsed by the MWBoS soon
Great Khans: Local power in the east, currently facing some minor problems with an 80s warlord
As for our GM, he left one day and never returned. Which is a damn shame, cause we really would like him back. Still, we run this thing mostly over discord and its almost a must-be to join, to be on there.
