T-Bird is right. Suggestin time. I’d say we put up a vote with 3 to 5 options.
Here’s what I’d throw in:
Exiles: The survivors of COH. More of a mutant gang than an organization since they no longer have the insane amounts of money or future tech NG had in Paragon.
Builders: A few people in the Champions Universe such as Grim Ichor remember a second, different life in another world. They try to rebuild the NG they had there but lacking the super science and money they are having a tough time, doing patchwork solutions using magic there science fails and general developing into something different.
Mirrors: Possibly the same persons than above but they found a source of resources and tech and thus vastly rebuilding NG as it was with some changes to adapt to the new world (less dark, no assassin squad for example). They get these resources from a mysterious source only some people in the leadership know? Dun dun dun. Future plot points.
I favor extremes so I like the first and third option here but the second is what Grim wanted and while I’d like the world to be that way ideas don’t become invalid if I don’t like them
