There is a darkness brewing on the blue waters of the high seas, sitting in the shadows and waiting for its proper moment to strike. Whispers about its return are murmured amongst the peasant folk and gossiped about in the nobility, but they are just silly rumors and stories... right? The seas always called to Percy Jackson and his adoptive sister, Piper Mclean. They could never stay away from the ocean's intoxicating call, even if they felt like they were stuck on land. But when tragedy strikes at the ages of 12 and 13, they had to think fast and logically, otherwise, they would end up and begging children, wallowing in their own filth and begging for crumbs. They stole and saved coins and small paper bills, saving for the biggest ship in the bay for them to buy. By the time they were 18 and 19, they were the most ferocious pirates on the high seas. Their crew grew and their ship was known throughout the different waters, they plundered and sung together, never letting destiny ever try to control them again. Little did they know, destiny had much larger plans for them. Annabeth was always a curious creature, asking questions and pestering poor people with her inquires. She always needed to know more and learn new things, it was one of the most fascinating hobbies of hers. She was a siren of the lost city of Atlantis, daughter of the famous Atlantian Siren Athena. She was a carefree child, swimming around and causing mischief. But one fatal mistake took that all away. She is now hiding amongst those who the Siren's think are demons, hiding in plain sight. Only her close friends Frank Zhang and Jason Grace know of her secret, but how long can she hide her dirty past?
