The Biblical name Korah is important because it became associated with Biblical villains and traitors for two reasons:
1. In the case of Korah son of Esau, both Esau and Korah waged war against Israel, and Esau was hated by God because of it according to Malachi 1:3. In these struggles Korah became renowned as a warrior and a fighter, and was legendary in Canaan because of abilities.
1. In the case of Korah son of Izhar, he is remembered for the rebellious action together with Dathan and Abiram against Moses according to Numbers 16:21. This story also appears in the Qur'an, where Korah is named Qarun (see Biblical narratives and the Qur'an).
Much like the Kohr Ah of Star Control, Korah was a renowned warrior. Also in the same page, there's lots of destruction and stuff.
Qur'an is also an anagram of Ur Quan. Could there be a relationship? Has this been mentioned before?
I don't think I've heard this idea before, but it is interesting and I can't think of any reason why it wouldn't fit. I'd wondered about the Ur-Quan name before. The UQM game seems to do a fair amount of playing around with names, that is they're obviously not just random creations, they tend to have meanings related to the race.
