"Young captain, please do not make a sound. You know the soulless singer, drifting upon the water."

You are a mermaid living near the Lorelei Reef. This reef-infested sea is a graveyard for ships, but also an Eden for you and your kin. When you begin to sing, even angels stop plucking their harps. Yet human desire is greater than fear, and you constantly face the threat of being hunted and imprisoned.

How will you write your destiny? Will you become a terrifying sea siren, or will you transform into human form and seize the crown amidst power and conspiracy?
