The people are free, but the town is still occupied by the Forsaken. They're cut off from their main force, so if we're to drive them out, now's our chance.
Their leader, Executor Cornell, is known for his unbound ruthlessnes. Also among them is Valnov the Mad, a so-called scientist who carries out inhuman experiments on the villagers too old to work the mines.
Take care of them all.
Progress
You're back, <name>.
Completion
We have the people of Emberstone on our side now thanks to you.
Head northeast and kill everything. The Executor is under the purple forsaken tent and the mad scientist is under the stables; both locations are on the water side of the Village.
Completing the quest advances the phase: There's a large squad of militia under Liam at the gate to the city near the Livery Outpost.
