Voe Deo, race of agressive black men in the Ekumena universe by Ursula K. LeGuin. They were conquerors who enslaved whites. Stuck with it for many years since, as i think it fits my style. No joke.
...until APB, where the game did not support multi-word nicknames, automatically cancelling it to Voe. It stuck, as it's concrete, short, easy to pronounce (unless you're Alp) and memorize.
Voekov is an entirely arbitrary creation when I joined =NX=, since i figured =NX=Voe looks retarded. Needed to elongate the name, and here it goes. Voekov seems pretty relevant given Volkov (also it's a common russian surname ).
