Illithid Dominion

The Illithid Dominion is, while not quite as unreasonable as planet-bound Illithid, still not likely to see you as anything but food or a slave. They do, however, respect diplomatic alliances, and generally obey the common Wildspace law. That does not mean you should trust a Union ship met alone in wild space, however, perhaps they MIGHT not attack first if you are flying a flag they have a treaty with.
