Cinderhame Mountains

Raised from the crusts of the world by powerful rituals wrought by the mightiest among the grey elves and wild elves in 52 I.R., the creation of the volcanic Cinderhame Mountains decimated the then-rising drow empire of Vilik Strad, from which it has taken that citadel thousands of years to recover.
Their volcanic floes now cooled, and their cones frozen into great spires of obsidian, the mountains slowly became populated with various humanoid tribes, many of whom now swear their allegiance to Vilik Strad, which once again turns its attention to the verdant forests of the Green Realm. The mountains are home to fire giants, hill giants, bands of ogres, trolls, gnolls, and more.
