Once upon a time...that's how the old stories always begin.

Once upon a time there was a king of a fallen kingdom. He was just and he was beloved. Or so the numbers said. One day, he gathered together the greatest, wisest minds in all the land—not sorcerers, but scientists—and he bade them fashion him a son. A prince. A perfect prince to embody his father's legacy.

The scientists each brought the prince a gift: beauty, strength, ambition, intellect, pride. But they must have forgotten something because when he saw the mermaids dance at the Cirque de la Mer, he ran away to join them.

For a year, he trained them, performed with them, thought he was happy. For a year he thought he was free. But then Nerites came: A merman who refused to be tamed. A captive from another kingdom. A beast in a glass cage.

The old stories always end with happy ever after. But this isn't one of the old stories. This is a story of princes and monsters.
