Thordak's Floating Bastion is a small series of Aetherstone-supported floating islands deep in the mountains north of Niðaróss. The islands have buildings on them and are tied to Thordak Faerdhal's guarded knowledge of Aetherstone, his dragon companion Skythor, and the trusted circle that includes Netheril Faerdhal and Kara Stormtongue. The bastion mostly follows the D&D bastion rules. Its exact mechanical facility list should be matched to the rulebook during later character-management work, but the current campaign functions are clear.
