Your Friend On The Inside

Your Friend On The Inside is Yarzill the Merc's introduction quest, available after completing Enter the Taskmaster at reputation with Netherwing.

Didn't think we'd leave you to face the fel orc army by yourself, did you?

<Yarzill's eyes flicker a translucent blue.>

Aye, we are here with you,. For every service you perform for the fel orcs in your quest to reclaim Netherwing lands, we'll be at your side to make sure that they suffer a sufficient setback.

You'll need to keep a low profile so as not to draw any unwanted attention to yourself during your sabotage missions.
