Encounter set:
We Must Away, Ere Break of Day
Encounter info:
Western Lands
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.)
