Speak with Kerr Ironsight at Stormfeather Outpost.
We need your help with somethin' more pressin', <name>.
The Horde's been gettin' bolder out here. They've moved in on our territory and started attackin' us outright. The Revantusk forest trolls are attackin' Stormfeather Outpost in broad daylight!
I need you to help out. Talk to Guthrum Thunderfist just outside. He'll put you on a gryphon to Stormfeather Outpost. Kerr Ironsight will fill you in when you get there.
