Setup: Create two separate staging areas: one for The Black Gate Opens and one for Mount Doom. Divide the players into 2 teams, one for each scenario. No more than 4 players can be assigned to each scenario and the number of players assigned to Mount Doom cannot be more than the number of assigned to The Black Gate Opens. Shuffle 1 copy of In Darkness Bind Them into each encounter deck. Place The Eye of Sauron in the Mount Doom staging area with its correspdonding side faceup. Flip this card over and set it next to the Mount Doom quest deck.

Ignore the Forced effect on the Mount Doom campaign card if it is in play.

Forced: At the end of the round, the first player chooses a scenario (The Black Gate Opens or Mount Doom). Each player at the chosen scenario draws 1 card. Each player at the other scenario reduces his threat by 3. Then, the player who controls the Gwaihir objective-ally may give control of it to another player (at either scenario).

At the end of the round, if the last player at either scenario is defeated, both teams lose the game. If the Mount Doom scenario is defeated, both teams win the game.
