The Sunken City of Xanthalos

Once a thriving metropolis, Xanthalos was swallowed by the sea during a cataclysmic event, leaving only a few towering spires above the waves. The submerged city is now a haunting, aquatic realm inhabited by merfolk and other sea-dwelling creatures. The ruins of Xanthalos are rumored to contain vast treasures and powerful artifacts, but those who dare to explore the depths must contend with dangerous sea monsters and deadly traps.
