You are playing Campaign Mode.

Setup: Each player chooses 1 Adaptation boon attachment and attaches it to one of their heroes. Shuffle the Stalking Goblin burden enemy into the encounter deck. Add Stalking Goblin and each attached Adaptation to the Campaign Pool.

Forced: At the end of each round, place 1 resource token here.

Resolution: If there are 6 or more resource tokens here, the thought of the captured villagers suffering weighs heavily on you. Add the Guilty Conscience treachery burden to the Campaign Pool.

You have defeated the enemy rearguard, but the rest have escaped into the Mountains of Mirkwood with their prisoners. You must track the goblins to their hold if you are to fulfill your oath.
