Mountains of Mourn
The Mountains of Mourn were originally the homeland of the Sky-Titans and Dragon Ogres, though for thousands of years it has been controlled by the Ogre Kingdoms.

As a matter of fact, the Ogres are probably the safest thing in the mountains, because you probably have to hire some as bodyguards if you want to survive.

The Granitetooth Graveyard
Every Stonehorn is doomed to slowly turn into stone as they die of old age. When this happens, they go to one of several "Stonehorn graveyards" to die, the Granitetooth Graveyard being the largest. Travelers sometimes come to this place as Stonehorns are known to contain precious gems within their stone skeletons. However, many of them find that some Stonehorns haven't fully become statues yet, and they don't like having their final moments interrupted...
