Where can I take the Tbc abyss cloak mission?

Below the Hellfire Peninsula, there is a camp called "Brokeback Sentinel", where tribal players can find "Crazy Ogas" to receive a series of tasks called "Jumping Cracks".

This task 1 * * * has three steps. The initial mission requires the player to collect 3 pieces of void energy, and the mission location is directly below the Qian Yue Plain. The second task is called "Void Mountain", which requires players to go to Void Mountain and collect 40 soul fragments of Void Mountain. The last task is called From the Abyss. Just take the mission items to the void mountain to knock down the summoned NPC.
