Prince Valanar at Death's Breach commands you to slay 10 Scarlet Crusaders or Scarlet Peasants and 10 Citizens of Havenshire.
10x Scarlet Crusader slain
10x Citizen of Havenshire slain
They make their stand now, outside of Death's Breach, futilely attempting to push us back in hopes of saving their horses, mines, lumber and citizens.
This will be your first lesson in Scourge warfare: TERROR!
Go to the front lines, south of here, and destroy Scarlet Crusaders. Leave their corpses so that we may utilize them for the death march.
But most importantly: kill the fleeing villagers. Soldiers dying are an affordance, but villagers? That is what strikes fear into the hearts of man.
