An Isekai Story

A once-great coastal city, now submerged beneath the waters of a vast inland sea. Thalassa is a place of mystery and intrigue, its ruins shrouded in the depths and its secrets guarded by aquatic creatures and ancient wards. Legends speak of advanced technologies and powerful artifacts that lie hidden within the sunken city, and rumors persist of surviving inhabitants who have adapted to their underwater environment. The air above the sea is thick with mist and the sounds of lapping waves, and the depths below hold both treasures and terrors.

The city is a haunting silhouette beneath the water, with crumbling towers and ornate structures visible through the misty surface. Bioluminescent flora and fauna illuminate the ruins, creating an otherworldly glow that beckons adventurers to explore its depths.
