Carried Away
The Wilds of Rhovanion#74 (x1)
Quest
3A-B (-)
When Revealed: Each player chooses a hero he controls, discards each token and attachment from that hero, and places it in the staging area. Each player discards cards from the top of the encounter deck until an enemy is discarded and attaches that enemy to the hero he owns in the staging area, guarding it.

As night falls some of your companions are carried off by unseen foes. You follow the sound of their cries in order to rescue them.
Each enemy guarding a hero cannot take non-combat damage. Each guarded hero is in play but under no player's control.

Forced: When an enemy guarding a hero is defeated, return that hero to its owner’s control exhausted.

When the players advance from this stage, discard each guarded hero.
