That's true. I'm not sure if the synopsis can be taken that literally, though. It would be odd for these characters to be assembled, and then have the looming threat be somebody completely unrelated to them. But... anything's possible.
It's perhaps worth noting that, in the comics, it's the Beyonder who turns Algrim into Kurse. Not that it's going to be the Beyonder, but... some other-worldly entity along those lines, I guess, maybe.
