Jothvauk

Jothvauk is a subterranean citadel of Yol Skerah. Surrounded by a lava lake, fire giants began building this hold early in the God Era. At the time, the Demon Spawn War (8972 GE - 9493 GE) was raging across the lands above, the Aerie of Dragons and into parts beneath it. Those that escaped the mining pits of Vith Ruus, went deep underground, building their bastion on the rocky isles dotting Onairions Pool. On a magma lake, hard to reach without fire-resistant boats or an airborne attack against a storm of magma blobs, the hold of Jothvauk was well-nigh impregnable. The fire giants of Jothvauk, independent of the Covenant, waged war on the same enemy, the demons. They battled Orcus's legions spreading across the surface above and through the caverns and tunnels beneath. In the Hoof Front (9245 GE - 9262 GE), the demons attacked Oratu Iru. Consideration was given to bypassing this area by passing Onairions Pool and the menacing spires of Jothvauk.

The isles were like the teeth of a great dragon, each a blockhouse bristling with defenses. The center-piece was Jothvauk, a place of walls and towers, castles within castles, certain defeat. We will lose less on a direct attack against Oratu Iru.

After the demons were pushed back, mining renewed in areas above, tapping the great adamantine veins of Vith Ruus. Jothvauk went on to ally with Tiamat in the First Dragon Wake (9251 GE - 9269 GE). Most of those that joined her died defending Gelok Himdah.

After the Demon Spawn War, Jothvauk's population expanded to include Fyrreid, Salamander, and other fiery brutes.

Today, unlike most fire giant populations across Bal-Kriav, those of Jothvauk predominately worship Tiamat over Surtur.
