Thunder Halls is a large unanchored earthmote. This floating island of rock flies an erratic path across Brucrumu's middle regions, from the High Wood Country in the west, all the way to its eastern opposite, the region Miradelgûn. The mobility of Thunder Halls comes from a perpetual storm in its lower quarter. This enchantment was put on the structure in the God Era. In the Demon Spawn War, Talos fought alongside the Quarat'un Covenant. He had no interest in seeing the prison fall into demon hands, so he put a perpetual storm under it, keeping it always on the move.
The largest features on the surface of Thunder Halls are its four colossal towers. Each are composed of the base elements, fire, water, earth, and air. At the center of these four towers is a prismatic glass keep. Those that have ventured to this place say the keep's prismatic glass has all the properties of the spell Prismatic Sphere. The pinnacle of rock forming the base of this keep and its adjoining towers are melded into one giant block. The work of making this was performed by a team of fire elementals and then battered into shape by the maul-like fists of colossal earth elementals. Lastly, the work was cooled by huge water elementals as it was smoothed and shaped by a team of air elementals.
In the First Epoch, the arch-magi Nears-nan-four was given a key to this ancient Coverant prison. A consummate conjurer, he expanded his knowledge from conversations with the prison's four elemental princes. The ancient knowledge of these elementals, along with a bit of their essence, Nears-nan-four created two powerful magic items. The blade Darkwind was forged in the Whirlwind Tower. The halberd Embercackle was made in the Furnace Tower. In the Earthen Tower, he found the great hammer Mudmaul. Nears-nan-four was never able to complete a third item that was to have its magical properties focused on water. While making this item, the elemental princess Olhydra broke free. She captured Nears-nan-four, returning to Chaos with the master conjurer in tow.
In 1823, an elite group of adventurers calling themselves the Scales raided Thunder Halls. After dispatching some of the place's guardians, they freed the places' top three prisoners. Once freed, these Elemental Princes fled to their respective Elemental Ring Worlds.
When the Elemental Princes were imprisoned in Thunder Halls, they were bound in their opposites. In the Furnance Tower was Olhydra, in the Waterspout Tower was anchored Imrik, in the Whirlwind Tower they put Ogremoch in a forever raging tornado, and in the Earthen Tower lie buried Yan-C-Bin.
