Conflict at the Carrock:
"A variety of new player cards offer exciting deck-building options, featuring new and familiar faces. Frodo Baggins is beginning to feel restless in the Shire while the Beorning Beekeepers offer their assistance to anyone willing to help drive the troublesome Trolls away. A Long-beard Mapmaker discovers a hidden Dúnedain Warning that just might help the heroes avoid defeat.
Conflict at the Carrock focuses on the lumbering Trolls terrorizing the Beornings, and while facing them in combat is fearful enough, Sacked! cards will endanger your heroes at every turn. Muck Adders will snap at your heels while you try to navigate the difficult locations surrounding the Carrock."
A Journey:
"During their search for Gollum, the heroes must take a detour in order to save a valuable ally. Since the Eagles play such an important role in the Shadows of Mirkwood Adventure Packs, players will want to retain the trust of their winged allies by saving one of their kin. In order to do so, they must bring the bird to Rhosgobel and seek out the wizard Radagast, who knows many secrets of the wild.
A Journey to Rhosgobel contains 60 fixed cards from the Shadows of Mirkwood cycle. In this exciting expansion, even more Eagles join the Tactics sphere, while Leadership players are given a Dúnedain Quest that will inspire confidence in their cause. The heroes’ trek through Mirkwood leads them to Haldir of Lórien, whose unnatural agility will aid the party in their task. However, the sky grows dark with foul minions of the Shadow, and every step toward Rhosgobel causes the heroes’ avian ally more pain. There is no time to lose!"
The Hills:
"Having lost Gollum’s trail at the Carrock, then embarked on a mission of mercy to Rhosgobel, the heroes now come to the hills of Emyn Muil, where they have only one objective: to find Gollum. This engaging Adventure Pack contains the first ever single-card quest, in which players must gather victory points by exploring a wide range of locations. Can you scour Emyn Muil and determine Gollum’s whereabouts before it’s too late? With 60 new cards for The Lord of the Rings: The Card Game, The Hills of Emyn Muil will augment existing decks while providing players with entirely new challenges for their heroes."
The Dead Marshes:
"The Dead Marshes is the fifth Adventure Pack in the Shadows of Mirkwood cycle for The Lord of the Rings: The Card Game! The hunt for Gollum draws to a close… unless he finds his way to escape once and for all.
The Dead Marshes introduces a Quest featuring the unique, new Escape mechanic that allows players to experience how slippery Gollum can be! With 60 new cards for The Lord of the Rings: The Card Game, The Dead Marshes enhances existing decks with new Allies, Attachments, and Treachery cards. This expansion also offers players an iconic Hero and a wholly fresh Quest experience. "

I mean, we already have 3 dwarf heroes, Dain Ironfoot, and other various dwarf allies...I love dwarves, so, hope Mapmaker is another one!
