Nefarian, AKA, Blackwing, AKA Victor Nefarius, Lord of Blackrock. When he’s not smashing intruders with his sorcerous might, he enjoys long walks through his domain, the sound of victims sniveling in fear, and quality time on his throne. His family is known across the land for their wisdom, restraint, and humility. Psyche! His family tree includes some of the most hideously evil dragons Azeroth has ever known, including his sister Onyxia and their father, Deathwing. They’re all pretty much the worst kind of awful, but true to his name, Nefarian is, well, nefarious. Not only does he have that being a huge dragon deal going for him, he’s also cunning and manipulative, as evidenced by his not-so-friendly rivalry with the elemental Firelord Ragnaros
Nefarian really, really loves experiments—specifically mad experiments. He loves them so much that he’s had himself re-animated and is now back from the dead, fully ready to resume his twisted work. Being a very goal-oriented dragon, he’s outfitted another secret laboratory deep inside Blackrock Mountain, complete with sparking lightning coils, vats of questionable substances, and the sounds of draconic agony. Nefarian spared no expense in decking this place out with all the tools, materials, minions, and victims he needs to succeed. He even had his pad tricked out with amazing Dark Iron technology (Hint: It’s not a sound system, though that would be totally sweet).
The black dragon Nefarian, son of Deathwing, claims the upper reaches of Blackrock Mountain as his own. Ruthless and cunning, Nefarian built Blackwing Lair as a home for the black dragonflight and his various experiments. It was also here that he concocted the ultimate army of home-cooked chromatic dragons, perfect for thwarting Ragnaros and his fiery minions that lurked under the mountain (Nefarian’s favorite pastime).
"The sinister energy Nefarian used to raise Onyxia still crackles on the blade." - Earthseer Nakza (Crul'korak, the Lightning's Arc)
