How do those mutations figure into The Milk Run?

At the end of The Ark Lords, OMCOM actually comes out and tells you the purpose of the mutations. He said he needed to create myriad autonomous probes, some with anomalous forms of propulsion, to scour the universe to try and find the origin of the Stareaters. He claimed, at the time, he thought the Stareaters were dangerous and perhaps finding their origin might give them a better handle on how to stop them.

Well as we learned at the end of Rome's Revolution, the Stareaters are not evil, have a noble purpose and are rather refined and considerate.

But the probes are still out there and OMCOM says information is starting to trickle in on some of the other sentient species throughout our galaxy. After all, you will remember we were given the appellation Species 927. That means there are 926 that came before us.

What OMCOM did not tell us is that the probes have also provided him with information concerning other universes as well. Think about that! OMCOM certainly has.
