The Golem Lord's Creations

This really screwed me up for about an hour after I queued in Blackrock Depths: Upper Spire.
I know not many people do this quest anymore, but I'm writing this in case, like myself, someone else wants to attempt this.

There's a mole machine pretty much wherever you spawn. Use it to go to the entrance, if you're not already there. Go left, then take the right (you should have needed to go through two gates). On the left side of the corridor you just entered, there's a troll named [npc=45820] standing next to a closed door. Open the door and head through.
As you walk in, you're faced with a ramp on the right and just a room of mobs on the left. To get to where you need to be for the quest, you need to click "The Shadowforge Lock" which is in the middle of all the mobs. Once you've clicked that key, it will open the door you need to go through. Head up the ramp, turn left and follow the corridor. This leads you to another room. Don't bother with that boss, and just enter the next room.

For the quest: kill 5 of the Golems, and then proceed to kill the boss located at the far north of this room.

Hope this helps others!

This is the Horde version of the Hunter Only quest given by Ormak Grimshot, an Orgrimmar Hunter Trainer.

There is an optional breadcrumb quest that preceeds it called Meet With Ormak Grimshot which is received when a player hits level 50.

Post-Cata class quest that rewards the T1 helm lookalike.

A list of all classes are as follows:

Deathknight : No T1, no dice.

Druid: Breath of Cenarius - Rewards with blue quality lookalike of Cenarion Helm. Both the alliance and the horde gets the quest from the same NPC.

Hunter: The Golem Lord's Creations(A)/The Golem Lord's Creations(H) - Rewards with blue quality lookalike of Giantstalker's Helmet.

Mage: The Pyromancer's Grimoire(A)/The Pyromancer's Grimoire(H) - Rewards with blue quality lookalike of Arcanist's Crown.

Paladin: Weapons of Darkness(A)/Weapons of Darkness(H)/Weapons of Darkness(Blood Elf) - Rewards with blue quality lookalike of Lawbringer's Helm, also rewards Blood Elf paladins with the Blood Knight Tabard.

Priest: Twilight Scheming(A)/Twilight Scheming(Blood Elf)/Twilight Scheming(Goblin)/Twilight Scheming(Tauren)/Twilight Scheming(Troll)/Twilight Scheming(Undead) - Rewards with blue quality lookalike of Circlet of Prophecy.

Rogue: The Dark Iron Army(A)/The Dark Iron Army(H) - Rewards with blue quality lookalike of Nightslayer Cover.

Shaman: Slaves of the Firelord(A)/Slaves of the Firelord(H) - Rewards with blue quality lookalike of Earthfury Helmet.

Warlock: Stones of Binding(A)/Stones of Binding(H) - Rewards with blue quality lookalike of Felheart Horns.

Warrior: A Dangerous Alliance(A)/A Dangerous Alliance(H) - Rewards with blue quality lookalike of Helm of Might.

These rewards are also quite good at their level if you don't have a heirloom helmet for your alt(s). I also have no idea why the horde priests get race specific quests.
