Within an unlit underground chamber, a black knight leaned over a detailed map, not of the continent, but of a specific region, expertly made with the help of scouts, both on foot and airborne, as well as cartographers of course, the Eastern Peaks were a very vertical place indeed, some of those peaks were really only accessible to those gifted with wings or otherwise capable of flight, scaling them was much too arduous and dangerous, but it also had many caves and caverns, the eastern people had settled into caves which openings were on the sides of certain mountains, it was home to a few species of dragons, trolls and many other monsters, but really only the dragons could contend with the eastern folks.
All else was considered prey and food, no matter how appalling and disgusting they may be.
