Goren Invasion! (Horde)

Objectives
Repel the goren invasion of your garrison.
 * Speak with Sergeant Grimjaw
 * Repel the Invasion  (1)

Description
The earth quakes beneath us, Commander. Our scouts are not returning. I can feel an attack creeping up on us, but from where?

Completion
The peons will clean this mess, Commander. Rubble and holes everywhere. The rest of us will look for hiding goren so that we may apologize to them for butchering their warleader.
