Ered Mithrin je veľké, kampaňové rozšírenie pre kartovú hru The Lord of the Rings: The Card Game a obsahuje 9 nových scenárov, ktoré si môžete zahrať samostatne, alebo v podobe príbehu. Toto rozšírenie zahŕňa všetky scenáre pôvodne uvedené v edícii The Wilds of Rhovanion a cykle obsahu Ered Mithrin, ktoré sú teraz zabalené v jednom produkte spolu s úplne novým obsahom kampane. Hra je v anglickom jazyku, tento jazyk je pre jej hranie nevyhnutný, preto aj nasledujúci popis uvádzame v tomto jazyku: As dark threats loom over Middle-earth, ever more people are torn from their homes and left without safety or refuge. What begins as a simple task of escorting a band of such wanderers to a new home quickly evolves into something drastically more perilous when a mighty threat emerges from the wilds of Rhovanion.  In the Ered Mithrin Campaign Expansion for The Lord of the Rings: The Card Game, one to four players explore the Wilderlands of Middle-earth in their quest to defeat a dragon that is terrorizing the countryside. Over the course of nine scenarios—which can be played standalone or as part of a larger campaign—the heroes must battle Goblins, explore the vast Wilderland, and steel themselves for a showdown with the dragon itself! This expansion includes all of the scenarios originally featured in The Wilds of Rhovanion and the Ered Mithrin cycle, now repackaged into one box along with all-new campaign content.
