2) Why did you names it "Cardolan" ? Cardonal use to be a word for a whole Arno's Sub-region and not a name for a specific area like "Evendim" for example. Also Cardolan use to cover (as a region ) all of the South Eriador and not just south of Bree. And finally the word Cardolan used to be a use of a different time period when Arnor still existed.
Cardolan is a subregion of the greater kingdom of Arnor. Arnor is comprised of three smaller geographic regions - Arthedain (encompassing The Shire, Evendim, portions of North Downs and Breeland), Rhudaur (encompassing the Lone-lands, portions of the Trollshaws, and the Ettenmoors), and Cardolan (the hills and wild lands south of Breeland and Lonelands). Further south of Cardolan to the ocean shore between the Brandywine and Greyflood rivers is considered Minhiriath.
