Author's Note: So this is an idea I've been playing with for a while and I hope you all like it!

Selena walked around the room slowly, letting her hand glide lightly along the table as she thought. The old man in the chair observed her carefully as she did this. She turned on her heel as if to speak, then closed her mouth and continued on her way. The room was silent for a long while, both of them deep in thought.

"You believe this is the answer then?" Selena finally asked, looking out the large window to the blue heavens as if they held the answer.

"What I believe doesn't matter at this point, Selena. Lives are at stake, and perhaps even the entire political structure of the world." The old man answered quietly.

"Lives may be at stake, yes." She paused for a moment before she turned to face him, staring into his large purple eyes. "But when are they ever not?"

The old man folded his hands on his chest and leaned back in his chair. "You know what I meant."

Selena laughed bitterly. "You're asking for what is coming, Dallas. You're looking a disaster straight in the face and you're inviting it in. You of all people should understand what a horrible mistake all of this is."

"Sometimes, disaster can bring us to the most wonderful, yet unexpected, places." He said.

Selena walked over the window and stood looking down at all the people bustling around on the streets below her. "They're a bomb waiting to go off. The final act of the play. They're…the downfall of mankind."

Dallas leaned forward and set his hands palm down on the table. "That may be true, yet it's never over until the credits roll, and sometime's it doesn't even end there."

Selena looked at him over her shoulder and frowned. "Dallas, the credits are already rolling, they are just so faint that you cannot see them."

"Sit, please sit." Headmistress McGonagall motioned to the chairs in front of her desk.

"Headmistress, have we done something wrong?" Hermione asked nervously.

"No, no of course not." The headmistress took a deep breath. "When I invited you all back for you eighth year, I never in my wildest dreams imagined something of this severity happening."

"So we have done something wrong." Ron interrupted. Draco frowned at the back of his head.

"No." McGonagall repeated. "You six have been called upon to go to Antarctica, for business I cannot explain to you."

Blaise laughed bitterly. "You can't send us off to some freezing continent without giving us any information. That's freaking crazy!"

McGonagall swallowed hard and continued. "What I can explain to you is this: wizards are not the only non-muggle people in the world. There are other groups that hide their lives away secretly, groups that we have not mixed with for thousands of years. The history was so horrible between us that we burned all the evidence of our encounters. We thought that if we did so they would cease to exist, and for a while, they did. There was one group of people, the Antarctican's, that were the overseers of these all people. They kept the groups separate, helped us keep our secrets safe, in a way they taught us everything we know today. Now they have called on you to aide them and for that very reason I cannot refuse."

McGonagall shook her head sadly. "I do not know what they want with you or if you shall return. I regret to do this deeply but I must send you, for if what they have described to me is as horrid as it sounds you will play a key role in saving us."

"I don't understand." Hermione looked at McGonagall with a look of confusion that she had never seen on the girl's face before.

"I'm sorry, but you must go now. There is only some much time for you to get there."

There were several cracks and then they were gone.

Chiron studied the seven young adults that sat before him. He could no longer consider them children after all they had been through, though in a way he wished for their own sake's they still could be.

"Heroes," He began. "you have been issued a quest."

Their looks of despair made his heart break for them even further. They bowed their heads silently, fiddling with whatever they could get their hands on to keep them from looking around the room and seeing their own emotions reflected back at them.

"Long before the time of gods or humans there was a group called the Antarticans. They are unlike anything one can imagine. Neither human nor god, they come from something called the in-between."

"What's the in-between, Chiron?" Annabeth asked with curiosity.

"A dark place in the spiritual world, it's like the crossover between heaven and hell. It's not a place of light or dark, but of every shade that lies within the spectrum. Dark, evil things emerge from the in-between along with light, wonderful things. It's because of this spectrum that the Antarticans have the power that they do. But to fully understand this you'll have to meet them yourselves."

"Where are they?" Percy asked quietly.

"Antarctica. They flourish there not only because of the cold, but because of the way the sunlight is received. Completely light for six months and completely dark for the other six, it is the perfect balance for them."

"So you're going to send us to Antarctica…." Jason trailed off uneasily.

"Unfortunately, I have no other choice." Chiron said softly. "If I did I would never wish this upon you. The Antarticans are not pure, behind everything they do lies both light and dark. Their intentions are never truly good and their character is questionable, but they also hold they key to knowledge and wisdom that Athena herself could never dream of obtaining."

They looked up at him slowly and fearfully, with wide, unsure eyes.

"The world you are about to enter shall open those eyes of yours more than any war ever could."
