Beautiful mountain terrain generation will bring you back to the highlands of Middle-earth time and time again.
In between these extremes, you will find virtually every single area mentioned by Tolkien, ranging from Lindon to the Iron Hills to Gondor to Mordor, complete with region-appropriate NPC spawns, vegetation and generated structures, ranging from small ruins of the former kingdom of Arnor to fortresses in Rohan to large settlements in Near Harad. From the frozen lands of the North, to the scorching deserts of Near Harad, to the steamy jungles of Far Harad, you can visit practically the entire continent of Middle-earth.
The mod adds 159 regions in its own right, with each region having many variations on the basic region theme.
