Report to Narkrall Rakeclaw at Bloodgulch in the Twilight Highlands.
<name>, the stronghold at Bloodgulch is the heart of the Dragonmaw empire in the Highlands. It is just up the river. Narkrall Rakeclaw is using his considerable power to amass a wing of drake-riders there.
For the Dragonmaw to succeed, Bloodgulch must succeed. Go to Narkrall and make sure it is so.
