Primal Fury

After you complete the quest, the NPC's just stand there. It is sort of anti-climatic. However, you may feel inclined to follow Hellscream and check out the gate to Taanan Jungle. I will save you the trouble, there is nothing to see and you will get phased into 100 or so Iron Horde elites. I will say, it was a glorious way to die.

For those who are finding it hard fighting their way up the hill, there is a sneaky way to get in. I went round the left hand side of the compound and jumped over the wall to get to Gogorek. Easy peasy :)

Bodrick Grey is at 66.92, 9.11 in Taldor. Take taxi to Fort Wrynn and follow the path northward towards Tanaan Jungle. Talk to him to start the battle and kill Gorgorek at 69, 3. Gorgorek is an elite with 2166k health, but when you find him he is supposed to be battle-weary and down to 541k. If you have issues slipping past packs of fighting mobs to get to him, bring a bodyguard & get some rep. Then head back southward to Azuka Bladefury. There are a couple of mobs on the way to her. You'll get a couple of Burning Blade initiates spawn to "help" Azuka. Burn them down. Azusa will die and leave her weapon Sanketsu where she was standing. Pick up the quest on the weapon (Sanketsu, The Burning Blade/sanketsu-the-burning-blade) - it will reward you with an epic 655 weapon for your follower. Then go speak to Thisalee Crow at 67.50, 7.59, a bit to the south, and follow her to the southeast (69.43, 8.98) There, Exarch Yrel will challenge Grommash Hellscream, but he backs down while claiming he is never beaten (yeah, right, whatever). Do not go up to the gate of Tanaan Jungle. My phasing was slow and after the Grommash rode off, I lingered to make sure I didn't miss anything. I rode up to the gate, where 150 level 100 elites promptly spawned on top of me and killing me instantly. I had to corpse-crawl out or take rez sickness. So after the challenge, just hearth back to your garrison and turn in both quests to Lieutenant Thorn. You will get follower [follower=217.1 domain=www], [item=120312], and [item=120311]. Good luck!
