After a while, Scamps squeezes through the bars. You hear a click in the distance, and the cage lifts slowly back to the ceiling. Truly an amazing beast, though a bit slow sometimes!
You enter a wider portion of the mines and are shocked by what you behold. Dwarves, hundreds of dwarves, all dead! Picks through their broken helmets, shattered barrels, signs of fire damage, skeletal hands wringing skeletal necks... it is all clear now. Whatever brought the goblins here, they hadn't met any resistance. This fortress had without a doubt fallen to a tantrum spiral. Marking this fact for posterity, you face the stairwell down into the depths. You will not leave without the treasure!
