Silver Sword (Superior): Illusions In The Fog

Southwest of The Orphans of Crookback Bog, across the treacherous marshlands and close to the water, is a rocky hillside with trees. Inspect the boulders here using the Eye of Nehaleni, and dismiss the illusion. Contract: Swamp Thing should start during this time.

The wolf sign is right of the entrance. Enter the cave you discovered. Defeat the Foglet in the initial chamber. Venture too far, and the named Foglet, Ignis Fatuus, must be defeated. Instead, stay in the initial chamber with the two skeletons, and check the stalagmite alcove to the left (southeast) for the chest.
