Voska used to be a rank and file Orcish warrior, tanking for The Horde's raid groups, until she came across an Alliance warlock and took her prisoner during one of those raids on Stormwind City. As a warrior she is forbidden from experimenting with Fel magic, but she's been learning a thing or two from her human pet, consorting with summoned demons, and learning to use Fel life-drain magic to further increase her already formidable strength. One of the side effects of Voska's experimentation was her skin changing from natural brown to Fel-empowered green, but the biggest side effect would be the raging erections she gets whenever she uses life-draining Fel magic to buff herself up. When Voska gets that look in her eye, you know it's Orc Cock O'Clock!™
