Destroy the Dragonmaw catapults.
While you were fighting the Dragonmaws, we discovered more of their plans.
Nek'rosh has built catapults and aims to lay siege to Menethil! And with the fighting in Dun Algaz, we're effectively blocked from reinforcements!
You need to take out those catapults. They're in the Dragonmaw encampment.
Here, take this tinder. Fight your way to the catapults and light them with the tinder.
And after you've done that, find and kill Nek'rosh. We need to cut this Dragonmaw beast down...at its neck.
