You're in a yacht your late-grandfather's gave you. You're not very fond of the vintage design, but it reminds you a lot of your grandfather. He did warn you in the will, however: "Be careful with that who sings in waters". You took the warning as one of your grandfather's jokes and never really thought about it.

You're lounging at the main deck, looking up at the stars and stuff. All of a sudden, you hear singing in the waters. Despite the warnings you've been given by other sailors, locals, and your own grandfather, you get closer to the waters instead of heading inside.
