[Sins of a Solar Empire]What wiped out the Vasari empire? What was chasing them?
gpt
Two hints:

- The sole Vasari warship that returned from their initial campaign against the foe had its crew "driven mad" by fear of what they encountered. Not merely despairing or terrified, but insane.

- The Vasari are by far the most advanced in Phase Space technology, including holding permanent portal-like stabilized nodes open for their ships to use.

Conclusion: *Something* came in from phase space, perhaps attracted by the stabilized nodes the Vasari created. *Something* so alien to even the Vasari, perhaps even to reality itself, that it just broke whoever perceived it. They never even had a chance to fight - they were lost as soon as they saw it.
