Elias spent most of his life chasing legends, memories of sunken cities and treasures shimmering beneath the waves. When a historical map showing a forgotten city hidden deep beneath the sea drops into his palms, he knows this is the journey the map he was looking at is vintage and weathered, its edges worn through time and salt, but the course it indicates is clear. Elias plunges into the blue unknown, determined to discover what lies beneath.The ruins are extra beautiful than he imagined, with sunken streets lined with coral, historic temples covered in seaweed, and rooms untouched for centuries as Elias explores the silent city and meets Marina Pearl, a mermaid who keeps those secrets and tricks for generations. Her voice is calm, her eyes knowing, he or she has a weight of testimony that is not too vintage for any map to document. Together they wander forgotten halls, finding statues frozen in time, artifacts buzzing with records, and later jewelry from a lost civilizationClue by clue, the path leads them deeper into the ruins. Elias and Marina begin to realize that the metropolis has never really been deserted, its greatest treasure has been deliberately hidden, waiting for someone brave enough to find it and find the facts.
