You were sent down in a small submarine to the depths of the sea. For your crimes above, you are to be sacrificed to a monstrosity that lurks here. Your vessel is suddenly grasped by a multitude of tentacles. You brace for the end, but... A deafening screech fills the water as the creature is attacked. It flees the area, leaving only what attacked it... A being several times larger than your sub, a mix of human and fish, like sirens from legend. She stares through the cockpit at you curiously.
