Monean (Star Trek: Refuge)

The Moneans are a spacefaring humanoid species from the Delta Quadrant. Originally nomadic, in the 21st century they discovered and settled on an artificially coherent planetoid of water, which they termed the Waters. In 2375, the Borg attacked the waters. The federation was able to arrive to transport all 80'000 moneans to their own star system, which struck a major blow against the Borg.
