Drahk'Suhl

Rivers of lava cut across plains of black sand and volcanic glass. The only vegetation consists of blood-red moss and a thick layer of shimmering slime. A jagged rock formation might be a piece of an ancient wall, if you stretch your imagination.

The Dragonridge Mountains (specifically the Stone Cage and the Shadowcrags, now under Khundrukari control) separate Drahk'Suhl from Kibosh and the Empty Forest. A series of canyons known as the Labyrinth further separates Drahk'Suhl from the rest of Argones. Due to ancient warding magic, any creature that wishes to leave must do so through the Labyrinth. These passes are guarded by the Ghaash'kala, tribes of orcs sworn to contain the evils of Drahk'Suhl. Beyond the Labyrinth, the mortal inhabitants of Drahk'Suhl include a brutal people known as the Carrion Tribes. Each tribe is devoted to an archfiend, and they engage in endless battles against the Ghaash'kala and the other Carrion Tribes.

Characters from Drahk'Suhl are likely associated with either the Ghaash'kala or one of the Carrion Tribes.

A variety of fiends in habit Drahk'Suhl, including devils, rakshasas, and demons.  These creatures are spawned from beyond the Underdark, emerging from portals to the Outer Planes discovered by Derrik Dankil during his Underdark Campaign.

Drahk'Suhl is riddled with portals to abyssal demiplanes, unearthly realms populated by fiends and other horrors.  These inner realms include vast and twisted forests, living oceans, realms of rusted iron, and stranger places.

Settlements are few and far between in Drahk'Suhl.  The Carrion Tribes are semi-nomadic, assembling camps in the crumbling ruins of long-forgotten cities built by demons and Ogres in ages long past.
