In the Hoof Front (215 GE - 230 GE), Orcus found a way to get a Progeny of Baltalas from its home world Muspelheim to Bal-Kriav. Unable to control a terror named Kerath, it tore a path through the demon city of Ghak, then melted its way to the surface. Rampaging westward, it slaughtered hundreds of demons that got in its way. When it reached the Covenant battle lines under Bahamut, they gave it a wide berth. Dim-witted by nature, this Progeny of Baltalas was lured into a trap set by Geb and an army of earth elementals. After falling into a spinning vortex of stones, Bahamut sealed the rubble with a breath that solidified the mass. A chimney was made so that mighty Kerath could blow off steam, raining molten rock, ash, and smoke. Even with these measures, Atlas forged great chains, the Kerath Anchors, binding Kerath to the volcano growing around him.
The volcano Sken Drog, Draconic for Chained Lord, is the encasing, the prison of the the primordial Kerath. A living volcano, it has been erupting in anger for thousands of years, only easing when it replenishes its energy from its own conduits to Muspelheim's fiery core. The baked lands of Kii Paagol, south and east of the volcano, are the product of Kerath's seemingly eternal anger.
In the Demon Spawn War (89 GE - 269 GE), Sken Drog's lava stone was used in the building of a great line of fortifications called the Viiz Bo Rei.
