So the humans in the first two galaxies were beaten by the Krell, Rin, and that robot menace faction all at once, and they fled into the third galaxy. But from what I know of the Krell, their hatred of the humans is great. They would have wanted to finish the job. So here's what I'm thinking:

The Harrison Belt, the long thin strip in the galactic north, is where the Tarakians have constructed their network of fortress-worlds. It's like a galactic line in the sand. And maybe the Krell and other empires can't get to humanity because the Tarakians are shielding them. They won't let you cross the line.
