Disclaimer: I do not own PJO, HO, or any of the characters except for Griefer and August. I have not yet read the third and fourth books in the HO series, so do not comment about characters/events I have left out (I also don't want you to spoil the series for me.)

Prologue

Percy and Annabeth tiptoed into the gloomy room and cautiously glanced around. It was just like all the other rooms in Tartarus: dark, sad, and reeking of death. There were bones scattered across the floor, and skulls that were frozen in a look of fear. There must have been a battle here, Thought Percy, as he noticed for the first time the vast amount of gold and treasures in the room. There was diamonds, emeralds, rubies, gold, jewelry, and even a few pieces of equipment. But out of all this, only one thing caught Percy's eye. He went over to it and examined it while Annabeth foraged for supplies. It was a small necklace, which consisted of diamonds going down the side of the necklace, and a beautiful grey snake at the end of it. The snake was coiled up, with it's mouth open, ready to strike, and was very detailed. Percy saw little, intracet scales carved in the necklace, and even saw minute fangs in the snake's mouth. Percy glanced over his shoulder at Annabeth, then looked back at the necklace. She would look nice with it on. After another quick glance at Annabeth to make sure she wasn't looking, Percy quietly put the necklace in his pocket.

"Percy," said Annabeth with a scared voice,"can we go now? This room gives me the creeps."

"O.K, Annabeth," answered Percy, and smiled to himself. He then trotted after her ready to face any danger that might come their way. Unbeknownst to the two demigods, however, was the shadowy figure perched on a ledge up near the ceiling.

"That's right, Percy," it sniggered when they were just out of earshot, "help me rise again so I can burn your precious camp to the ground. And the best part is, it's going to happen. And you will be powerless to stop me." Percy and Annabeth we're even farther now, so Griefer could raise his voice a little. "We shall meet again, Perseus Jackson! And until that day, your life shall be yours. But when that beloved day comes, you shall die along side all of your friends. Thus is the fate of the hero!" Griefer said, and glided off to follow the two Half-Bloods.
