The Beor Mountains are the tallest mountains in Alagaësia, being over ten miles high (nearly twice as tall as Mount Everest, the tallest mountain on Earth). They are located southeast of the Empire, across the Hadarac Desert. The Beors are steep, have vegetation only at their bases, and are almost maze-like with valleys and crevices. Beneath these mountains the dwarves have one of their cities, the giant Tronjheim, which is located in Farthen Dûr, the largest mountain of Alaegasia. The dwarves believe they were created out of the living granite by their god, Helzvog.
The region has five species unique to it. Among them are Feldûnost, large goats that the dwarves use for steeds; Beorn, enormous bears for which the elves named the range, Orik the dwarf said that the true name of the Beor mountains is a secret they share with no other race; and Nagra, gigantic boars which the dwarves consider to be a delicious dish, though they are rarely hunted since they are so vicious. Another species native to the Beor Mountains are the Fanghur, which resemble dragons, though they are thinner, more agile, and a muddy green color. They attack their prey with their minds to incapacitate them. The last of the species is the Shrrg, a gigantic wolf swift enough to catch a Feldûnost and strong enough to kill a Nagra
