Concerning the Mountains, (Atheleas, Footsore, Scary, Fire)
Talmids original Map actually labels a small part of the overall range as the Scary Mountains.Â
Overall, they could be called the Atheleas Mountains, or that could be a small portion that has Athelas on it.
The Fire Hills could refer specifically to the particular Hills and Mountains that light up with Fire Beacons. I assume some of the foothills also have some beacons to carry the signal in deep fog.Â
... I have no explaination for the footsore mountains. If the first mention of that is in a book of legends that Lady Jonna read, maybe that was a fictional name for the real mountains, and it stuck. :P
