I'm not sure whether I'm in the right section of the forum with this question, but anyway - does anyone know if there is a MERP module (sourcebook not adventure) dealing with Druwath Iaur & the Enedwaith coast north of it? I have a feeling both "Northern Gondor/Isengard" & "Dunland/Southern Misty Mountains" do not quite cover this territory. However, I do remember having come across maps of this region on the Net, so I suppose there should be a module which includes that area.

The one you're thinking of is Tales of the Westmarch by Randel Doty (if I've spelt his name right).

I don't think it covered Druwaith Iaur, just the Westmarch between R. Isen and R. Adorn, but they would be the closest neighbours...

Southern Gondor: The Peoples also had divisions amongst the Daen peoples, some of whom lived pretty far West on Andrast or in that remote western pass beyond the White Mountains and could be useful.
