To the Skies! (Horde)

Objectives
Gain access to the Lightning Vein Mine.
 * Speak to Lor'themar Theron to begin your mission
 * Assault the Lightning Vein Mines

We can use the pterrorwing that you found to strike a decisive blow against the mogu. Their mining operation is vulnerable to attack from the air, and your pterrorwing is the only beast we have capable of flying out there. Let me know when you are ready!

Progress
It's time to begin your mission!

Completion
Incredible work. This presents us with a monumental opportunity.

Stage 1 - Taking Off



 * Mount your Thunderwing!

Head south a few yards to approach the Thunderwing, and Elsia.
 * Mount Thunderwing
 * Approach the Mine Entrance
 * say
 * say
 * say

Hop on:
 * say
 * say
 * The thunderwing takes off.
 * yell

The pterrorwing will fly westward through the Diremoor then turn northward to start circling clockwise around the Lightning Vein Mine and the Thunder Forges.

Stage 2 - Intercepted



 * The Zandalari have spotted you! Defeat your attackers!


 * Defeat your Attackers!

Zandalari Beastcallers fly up behind the adventurer and will start attacking it with throwing axes. Classes with ranged abilities may stay on their own mount, but the skyscreamers will occasionally get out of range of each other. It will thus likely be easier to Jump! with the bonus action button to the mount of the targeted beastcaller. While circling the mine, the champion is buffed with Thunderous Innervation: "Killing enemies heals you for 30,000 every 1 sec for 5 sec."

One beastcaller will spawn, then two, then finally three. Take them all out. The skyscreamer will circle around before reaching the northwestern mine entrance, where Beastmaster Horaki will shoot the player off its mount!
 * yell

Stage 3 - Master the Beastmaster



 * Horaki has knocked you from your mount! Defeat him!


 * Horaki defeated
 * yell
 * yell
 * yell

Beastmaster Horaki is a level-90 elite Zandalar troll with nearly three million health. See his article for a full strategy, but get out of the Frost Shot area of effect before he launches the Hail of Arrows. The hails will last for the rest of the encounter, so get just outside of the arrows' area of effect (marked by a red circle) to not waste space.

Finish him off to start the next stage.

Stage 4 - Into the Mines



 * Meet up with Taoshi, your Shado-Pan Contact.


 * Joined with Taoshi
 * say

Taoshi is standing by the cave-in. Speak with her:
 * I will destroy this cave in, and then we can sneak in from behind. Let me know when you are ready.

Stage 5 - What's Yours is Mine



 * Make your way to the mine's main door.


 * Cave-in cleared
 * Make Your Way to the Mine Entrance /
 * say
 * Taoshi runs up to the cave-in, drops a bomb, and then takes cover behind the adventurer.

Head into the freshly-opened mine and start killing a path to the southwest through Shan'ze Electrocutioners, Shan'ze Slavers, and Saurok Slaves to reach the southern entrance. During this time, Taoshi will chime in randomly:
 * say
 * say
 * say

Final Stage - Cover Me



 * Cover Taoshi while she deactivates the lock on the mine door, and defeat Slavedriver Shiaxu.


 * Shiaxu Defeated /
 * Mine door unlocked
 * say
 * say
 * yell
 * Taoshi drops what she's doing and runs to the southern door.

Slavemaster Shiaxu is a level-90-elite mogu with 2 million health. See his article for abilities and full tactics. In short, get out of the Capture area of effect, as he will Deadly Kick the same area on his next attack, and get at least 40 yards away from the shackles to break the Chains.

Finish him off:
 * yell
 * yell

This completes the "Take the Forge" portion of Isle of Thunder (achievement) as the scenario concludes.

Finale



 * yell
 * Sunreaver Rangers charge in and clear the mine of mogu.
