You are playing Nightmare mode.
Forced: At the end of the refresh phase, choose an unclaimed Clue card not attached to a Mordor enemy and attach it to a Mordor enemy, if able. (If it was guarded, detach the encounter guarding it first. The newly attached Mordor enemy is now guarding it.)
If at any point there are four or more Clue cards attached to Mordor enemies, the players lose the game.
"Through Mirkwood and back again it led them, though they never caught him."
