Percy glanced at the dawning sky, thinking of Ogygia and Calypso. He wondered of what hands the Fates dealt to make the poor girl's life miserable. Despite Percy's protests, her image lingered in mind, a permanent resident.
His sixteenth birthday and Luke went through his mind, but still she remained. He thought of returning positively; he could escape the prophecy, but then remembered he couldn't return. He wouldn't let that stop him; he'd found the enchanted boat that brought him back.
With this hope, Percy hopped on, saying, "Ogygia." It took off, never returning.
