Obviously trolls. Even Bilbo, in spite of his sheltered life, could see that: from the great heavy faces of them, and their size, and the shape of their legs, not to mention their language, which was not drawing–room fashion at all – The Hobbit

When Revealed: Add the set-aside Troll enemies and the Troll Cave to the staging area. Shuffle the encounter discard pile back into the encounter deck.

Forced: If there are no Troll enemies left in play, or if there are no cards left in the encounter deck, advance it to the next stage.

Any time players would place progress tokens on this quest, discard an equal number of cards from the encounter deck instead. (Progress is placed on the active location before triggering this effect.)
