Dark Reign - Lair of the Black Wing
For this task you need to go to the Broodlands. Once you zone into the Broodlands (north out of Lavastorm Mountains) follow the blue line on your compass to your quest objective. (If you don't currently have your compass up hold ALT down and press D (Alt + D)).
For this task you need to enter the Lair of the Black Wing and hunt down 6 Black Wing Drakes. In the map below I have blue text over the part of the zone you'll find the Black Wing Drakes. You'll only need to kill 6 of them, every one of them has a 100% chance of dropping the fangs you need to collect.
They're spread out throughout the dungeon, I usually go right after the first room and pull each room until I reach the one far northeast. Then if none deagro'd you or you missed looting one in the hoard of corpses, you'll be done. If either of the two above things happened just continue west through the hallways killing more.
