With most of the Saurfang line dead.
Broxigar (War of the Ancients to Sargeras)
Varok (Orgrimmar to Sylvanas)
Dranosh (Wrathgate to the Lich King)
One member of their line is still out there somewhere. Thura, cousin of Drannosh and niece to Varok and Broxigar.
She has only appeared in the book Wolfheart and has been seen in the game files but never truly added to the game. Any chance she'll make some in game return soon?
