In Norse Mythology Vor is a goddess of the Aesir.
Snorri Sturluson tells that she is wise and alert, and that she misses nothing.
In Lois McMaster Bujold's science fiction novels, the Vor are the noble families of the planet Barrayar. "Vor" is a prefix applied to the family's name, most notably that of Miles Vorkosigan, the protagonist of most of Bujold's novels.
In aviation VOR stands for VHF Omni Range.
