I came up with Roivaskrad when I found the first class that got me in a game: Death Knight in WoW, as I have always gravitated toward the damage focused classes that either use a big 2h weapon or flashy spells and the DK was both of those. I figured as a Death Knight that the dark background (reanimated to serve some - usually - evil being) along with now being a hero could be combined to make a good name thus the origin: ‘Dark Savior’. But it just seemed too generic.
So I added some of my personality to it by reversing the words/letters: ‘Dark Savior’ <-> ‘roivaS kraD’ and of course fixing the capitalization to fit the new order and combined them into a single name as that seemed to roll of the tongue easier: ‘roivaS kraD’ -> ‘Roivaskrad’.
I was definitely the first to be using this in WoW as I had the only 3 characters with this name for like 3-4 years, but it seems to have caught on as I have moved servers many times. I’ve also often been asked if it’s Russian, but as I don’t speak Russian I simply say no and assume that is correct
SN: I pronounce it: roy - vus - krad
