Yes! I've got it. It seems to me rather natural to assume that, given the nature of the attack and the human revenge complex, that people would want a tangible enemy to attack. In this case, the good honest people of America (and the rest of the world, for that matter) want nothing better than to get their hands on some genuine, gribbly, aliens, and kick the shit out of them.
Hence the rise of the Frontiersmen.
So named, partially after the newspaper that is co-funding them, but also, according to one Frontiersmen spokesperson, "The Event has opened up to us as a race, a whole new frontier of warfare that we have never dreamt possible."
These armoured and armed men (and women) are self-proclaimed "Alien Hunters" and, whilst not government funded, are certainly government legitimised, and receive state cooperation in most things. Ostensibly out to "protect all human citizens", the Frontiersmen have the right to question anyone and everyone who may be an alien "sympathiser" whether they know it or not. The Frontiersmen target all shady characters, and also anyone who has ever claimed to be psychic, or a magician, or a fortune teller. Sometimes these people are simply questioned, given reassurance of the Frontiersmen's aid, and sent on their way, to be secretly spied on for the rest of their lives. The less cooperating of the Frontiersmen's captives are never seen again...all in the name of "world security".
The Frontiersmen have a uniform of sorts (pics to follow), and are funded by sources unknown. The beleaguered government hasn't led an official investigation into the organisation, as they are simply glad there is another body of authority helping them keep peace and making the citizens of America feel safer at night.
Old servicemen, retired policemen, the odd mercenary and hundreds of incensed civilian volunteers make up the ranks of the Frontiersmen, but they also enlist their own psychics, or those claiming to have proven psychic powers, to help them in their quest against the "enemy on the other side".
Anyone acting un-American, or even in an "inhuman manner" is fair game for the Frontiersmen. They are a thinly veiled force of oppression, but with the right press and the government's inaction, (not to mention their small but growing fanbase) they are allowed to do as they will on the streets of New York, all in the name of the anti-alien crusade.
All the other plot points will be used, but I think the Frontiersmen will be the main focal point to begin with at least, and our (anti) heroes can choose whether they see the Frontiersmen as a good, honest bulwark against the horrors of different planets, or painted fascist thugs using a disaster to perpetrate their own sadistic rule on the streets of the capital. They receive training and are equipped like a standard police force, except with less guns and more "alien hunting" equipment (tazers, mace, "psychic radar", spring-loaded nets, etc).
I might even make up a few NPCS as lead Frontiersmen captains.
What do you all think?
EDIT: I’m also just whipping up some IC game threads, located in Central Park, Happy Harrys, The Docks, and a Russian café.
