Radrundaar is a fabled Dwarven stronghold and seat of the great Dwarf kings of old. It is traditionally believed to be the seat of Dwarven power which ruled over a vast empire of Dwarves, located in the northern reaches of Thalasia. It was considered to be instrumental in the downfall of the Tiefling Empire of Bael Turath during the last great war, and is rumoured to be where the Warforged were created.
After the great war and the Rain of Colourless fire which brought the fighting to an end and the covered the Tiefling Empire in the Grey God’s Veil, the dwarfhold disappears from the histories. The Dwarven race, long in decline, began a migration from the fabled realm, and those few Dwarves that are now encountered remain tight-lipped about the location of Radrundaar.
