Under the Ash Mountains is the fourth Adventure Pack in the Vengeance of Mordor cycle for The Lord of the Rings: The Card Game. 

Your pursuit of Thane Ulchor has almost reached its conclusion. All that stands between you and this dastardly foe are the tunnels of Torech Gorgor under the Ash Mountains. As your journey reaches its final stages, this 60-card pack takes you deep into this labyrinthine cave system where you’ll face dwindling supplies as well as the nameless terrors that dwell there. Food and water will be scarce in these darkened tunnels, so you must conserve your resources if you hope to survive.

This task can be made easier with a little preparation and Under the Ash Mountains gives you plenty of tools to deal with dangers you'll find in the tunnels. Numerous allies can help you find your way, and a new Contract ensures you have a diverse array of options as you inch closer to Mordor. Do you have the will to find your way through before all hope is lost?
