The Journey Has Just Begun

Circa 9.0

This quest is NOW granted by Overlord Natoj, a troll with a blue mohawk hanging around just inside the front gate of Orgrimmar, on the right side, in front of the Orgrimmar General Store.

Alternatively: /way 52.65, 82.48 Overlord Natoj

Having had to Google around to figure out how to learn the pattern, I can relate that once you learn this pattern, DO NOT DROP LEATHERWORKING as it will be lost. This pattern is awarded by completing the quest and GMs can't reinstate it, nor can the relearn options in Oribos et cetera.

Can confirm that you still need 300 skill in Classic LW in order to pick up this quest (after turning in the quest from Onyxia's head).

For the curious, this quest is still in the game and works as of patch 4.0.6. I was able to get it on my druid after turning in the Head of Onyxia to Neeru Fireblade (you don't bring it to Thrall anymore on account of him not being in Orgrimmar) and then going to Overlord Runthak near the entrance of Ogrimmar.
