Kuri'Vaim the Slayer

Forged in the Flames of Mardum by a pair of Twin Demons, Kuri & Vaim. Their ultimate sacrifice was to place their own Demonic Souls into each weapon, together staying strong. The weapons were passed onto a Doomguard of extraordinary powers, however during the claiming of Mardum by the Illidari, one Demon Hunter called by his name "Voidgaze" slew the Demon, draining his essence and claiming the Warglaives for his own.
