Yor

A "gift" from Illidan Stormrage to accompany Nexus-Prince Shaffar, Yor is a void hound of unlimited savagery and power. The prince's advisors warned him that Illidan's demonic gift was most likely a ruse set to betray Shaffar once he had met his goals. The prince fed those advisors to Yor... but has since kept the hound in a stasis chamber, just in case.
