And we will band together, and stop this "Black-Wave Menace" and save the entire multiverse!
Or something like that.
So, do we have an explanation for why our people our so susceptible to black sea waves? I would assume BWM [Black-Wave Menace] would be messing around with the black sea one day, and happens to hit them, and by exposure, they can now "ride the wave" so to speak, and go to new worlds.
