Percy Jackson, son of Poseidon sighed, utterly bored of life at Camp Half-Blood.
"Percy Jackson," Chiron called the demi-god to his place. Chiron paced on his horse ass. "Have you ever heard of a three-quarters blood?"
"How is that possible?"
"This one's father is Apollo; two of their grandparents are Selene and Zeus. Her powers are vast."
"It is a girl?" Percy sat down.
"Serena Cosmos is her name. She is an heiress three times over. She has powers from her three ancestors. She is to be put in cabin Apollo when she gets here. Her grandfather is still in eternal sleep," Chiron was nervous.
"Endymoin?" Annabeth questioned, recalling the myth.
"Nah, that asshole is a traitor. That myth was misconstrued. Selene actually fell in love with a soldier named Galen. Chaos is the reason Serena seeks Camp Half-Blood's safety. Endy wants one of Serena's birth rites while Chaos wants to put her in eternal slumber." Mr. D. stated, hating the self-righteous bastard.
Chiron unfolded a tapestry, which depicted a silver-haired maiden fighting a dark-haired man. "Serena is the reincarnated Moon Princess, wielder of the Silver Imperial Crystal and Sword of Artemis."
Annabeth stepped back, stunned. "That sword can kill immortals with just a cut."
"True, but we are more concerned about the Silver Imperial Crystal since it can destroy the universe. Only Serena and Artemis can handle the sword." He had known Serena as the moon princess of old.
"What is stopping this Serena from destroying Olympus?" Annabeth as usual was suspicious. She crossed her arms.
"Her pure heart and eternal soul will not allow it. She befriended Hades' daughter when no one would."
"You mean there is a half-blood of Hades." Percy felt himself becoming less important.
"No, Hades' two children are both immortal and Persephone's offspring. Hannah is two years younger than Serena, but Alaric is two years older than her," Chiron corrected their misconception.
"Serena is hiding in the old temple of Apollo's off the coast of Maine." Mr. D. pulled down a map of the island and the way to reach it. The temple acted as a modern day lighthouse, surrounded by turbulent waters and jagged cliffs. Unusual fish heads poked out from the water. "Your quest begins at dawn, heroes."
