Eriador, the lone-lands described in The Lord of the Rings, comes alive as never before in this supplement for The One Ring, the official tabletop roleplaying game based on the works of J.R.R. Tolkien. A region often described as deserted becomes a crucible for adventure, offering many hours of gameplay.

Chapter 1: Fog Over Eriador offers a description of the regions that once were part of the kingdom of Arnor, with a focus on the city of Tharbad. Chapter 2: A Gathering Storm provides the Loremaster with a set of narrative elements aimed at building a possible future for the land of Eriador as a whole. Chapter 3: Landmarks adds twelve sites of interest in the style of the one presented in the core rules.
