Against the unending mist and unseen terrors of the Ethereal Plane, the Radiant Citadel stands bright as a bastion of hope. It's a living relic of the ingenuity and collaboration of twenty-seven great civilizations. Abandoned and lost for ages, the Citadel was resurrected from its slumber and reclaimed by descendants of those societies, though some peoples remain missing. The city serves as a nexus of diplomacy and trade, a repository of histories and secrets, and a thriving sanctuary for those seeking safety or a better life.
