Lone Siren

“Open your eyes, dear, for you are alone.”
“While you were asleep, everybody left.”
“Why did they leave you alone? Why you? Why now?”
“Open your eyes, little mermaid. Open your eyes and search for your kind”

Those are the first words that start you out in this fairytale of the dark depths.
The titular siren, who always liked to explore and have her own small hideouts, wakes up to the sudden realization that she has been left alone.
The search for her people and her family will make her explore the now abandoned region, and met some interesting people, but will also expose her to many dangers.
