This has come up a few times actually. Basically, the plot of that game was one of the worst thought-out, least consistent pieces of the Expanded Universe ever, and that's saying something. The faction itself is also pretty irrelevant and tiny. There's no way it actually spanned Vjun to Mustafar, considering those planets were on opposite sides of the galaxy, and known to not only be well within the borders of other known factions, but also had those groups known to be operating out of those planets right before and right after the events of the game (so, presumably unless they temporarily vacated or just didn't realise there were more people there, it was controlled by them concurrently as well) meaning both of their capitals were apparently, at best, secret bases within other peoples' territory, and they didn't control anything else.

Not to mention they threw together the most random assortment of unit types they could think of, including dark troopers which hadn't existed for some time at this point. There's a lot we can try to retcon within the mod, and there's a lot of wonky stuff within the EU we have to work around, but it's like they went out of their way to make the least feasible faction they could out of stuff that was on opposite sides of the galaxy, didn't exist anymore and was controlled by someone else.
