You are right, but FRoME it is.
I wanted to write about their tribes but don't know how to spell the one... balthlocth

I read somewhere in books that actually, when Numenoreans came to Middle-Earth after the fall of Numenor, they formed United Kingdom of Dunedain which was divided in two:
1. Arnor - High King Elendil
2. Gondor- which was split into two - Ithil Kingdom and Anor Kingdom and both capitol was Osgiliath. Isildur ruled Ithil and Anarion ruled Anor. Gondor was split into these until Sauron returned and captured Minas Ithil. I got nice ideas about these but I've got headache right now so I can't think normally so I will post those tomorrow.
