I know it's a minor issue but I don't like the name Rhuduar for a location range north of Lone lands.

In most if not all the maps of middle earth in google search you will notice that Rhuduar is located in Trollsaws.

I understand that Arnor's sub-kingdom took Rhuduar name and expanded it all the way to weather top but that is not the case after the fall of Arnor as Rhuduar became Trollsaws.

Now I don't want to go against the books and the lore and of course I want to see what is north of Lone lands one day BUT the name in my opinion fits well in the region is Weather Hills.

Weather hills feels more catchy and fits more for the region close to weather top.
