The Oathbearer's Road

You look at the letter sealed with a common rune known to the ironbreakers. Anyone who didn't know the rune and broke the wax seal would see the parchment go up in flames before they could read it, but you know better. You correctly break the seal and reach the contents within. These are orders, calling any able ironbreaker to travel with haste to aid the dwarfs of Karak Azgaraz in safeguarding the Marshroad in the Marshes of Madness.

Travel to the Marshes of Madness and find Harbrin Norinsson at Murdogh's Hold.
