Discliamer: I don't own Doctor Who or Percy Jackson

Prologue

There was a war, The War in Heaven, which shook the very fabric of the universe. One man, a renegade of the Great Houses of Gallifrey, stopped The War from ever happening, annihilating all combatant sides in one instant. Or so he thought…

TARDIS, en route to Earth

The Doctor was busy messing with the controls on the console when a warning light began to flash. A jolt rocked the TARDIS as the cloister bell began to ring. The read-out began to spit out a garbled message about a temporal implosion, but suddenly the cloister bell stopped ringing, and one word printed out on the readout – Celestis. The Doctor felt his very soul turn to ice as he read the word. His expression hardened as he set the coordinates for Earth.

Camp Half-Blood

Percy was happy to finally have a chance to relax and leave the war with the Titans behind him. He was also enjoying spending time with Annabeth, without the constant interruptions and quests, but, as he watched Chiron sprint toward his cabin, he knew his chance for peace and quiet was over.

"Bad news Percy," Chiron intoned, "I am afraid Rachel has experienced another vision, a vision of 'a being that walks on storms. He has many names, but none are truly his, and he has worn many faces throughout history. He has seen the beginning and end of time, and he is coming: the Gods will tremble before him.' I have no idea what this could mean, but I worried what it could mean. As soon as Dionysus heard the vision, he headed straight back for Olympus; I have not been able to contact any of the Gods since then. I need you and Annabeth to head for New York to see what has happened to the Gods.

"I will leave as soon as possible. Can I bring anyone else along, I might need help?"

"No Percy, I will need the rest of the campers to prepare for war. I fear this coming threat might be worse than anything the Titans could throw at us."

"Worse than the Titans?" Percy asked incredulously, "How could anything be worse than what the Titans tried to do?"

"I don't know Percy," Chiron slowly answered, "I just have a feeling."

Percy quickly readied his equipment and met Annabeth behind the Poseidon Cabin, and they set off toward New York.

Well, I had the War stuck in my head, and I saw the perfect way to tie it in with Percy Jackson. I make the Gods look bad later on, but I really do like the Percy Jackson series. Please review, I have more chapters, but I would like to know how this one is perceived before I continue.
