Trolls of the Misty Mountains is a supplement published by Iron Crown Enterprises (ICE) in 1986 for the fantasy role-playing game Middle-earth Role Playing (MERP), which is itself based on the works of J.R.R.
In The Hobbit, Tolkien's precursor to The Lord of the Rings, Bilbo Baggins and his companions encounter some of the denizens that live under the Misty Mountains.
This book contains three adventures that take place in the vestiges of the former kingdom of Rhudaur that once lay against the eastern side of the Misty Mountains.
[1] The adventurers are hired to reconnoitre the route of a proposed road to be built between the keeps of Daenos and Elnost, rooting out any potential dangers such as trolls and orcs.
[2] Some reviewers were generally dismissive of this book, finding it lacked originality: Denis Beck, in the April 1987 edition of Casus Belli (Issue #37), disagreed, calling theses adventures "very classic."
