Move the Mountain (Horde)

Objectives
Detonate the Hidden Explosives to lure Skullcrusher the Mountain away from the Twilight Gate.
 * Hidden explosives detonated

Description
If the Twilight Gate is to fall, we must get Skullcrusher the Mountain out of there!

Before they left, I saw to it that your Kor'kron assassins took some explosives hidden in a Twilight's Hammer crate. By now, they will have planted them on the steps leading up to the upper portion of the Citadel.

I want you to set the explosives off and then signal us when that monster's out of the way.

That's when we'll attack and finish off the ogre compound!
