Annabeth Chase was flying through the night London Sky, trusting the magical Mist to hide her from the prying eyes of the sleeping mortals below.

Percy Jackson, her sort of boyfriend, was still in New York, spending some time with his mother and stepfather.

He had lent her his Blackjack for this trip, which Chiron was so insistent upon that she had had to give up the construction design of the city of Olympus to go collect a Demigod here.

His location was still a mystery, or Annabeth would have left this cold and dreary weather long ago.

Suddenly, she felt dreadful cold seep into her bones. At the same moment Blackjack became very agitated and started swishing and whirling her. She had just enough control on the Pegasus that she could barely direct him to a lake before they both crashed.

Thank Athena for the special healing ability Half-bloods had, or she would be less than a Seaweed floating in a river.

Quickly she hurried out of the water, because this was obviously a work of some Monster.

She went through the whole list of Greek Monsters in her mind, but came up empty. There was no such creature that could induce fear and dread without ever being seen. Most of them relied on their shape and ferocity to scare the Heroes.

She pulled out her Celestial Bronze blade and the Invisibility Cap given by her mother, and did a quick sweep of the nearby area.

She saw a bunch of black cloaks surrounding a boy and quickly ran there to help.

As she went closer, she started hearing voices.

"You are a disappointment."

"Help… Annabeth!"

"I trusted you…"

She fought through the vivid flashbacks her brain was trying to force on her, and instead drove her blade through one of the Cloaks. It dissolved into dust.

The other Cloaks turned, their focus now concentrated on her.

Her legendary Invisibility Cap was useless.

The dread and fear were too much.

Her blade slipped from her hand, clattering on the road.

She could see Kronos, controlling Percy's body, slicing his Scythe towards her, and she couldn't stop him.

She heard an "Expecto Patronum!" followed by a blurry white light, before darkness engulfed her.

Annabeth woke up to hear many people talking. Sensing that she was in no immediate danger, she didn't open her eyes, instead trying to gather more info. It was Strategy 101.

"Stop making stories, Potter. Dementors can't be killed."

"Shut your mouth Snape. And don't say another word to my Harry."

"Do you want more chocolate? Remus came back with enough to fill a pot!"

"I'm alright Mrs Weasley!"

"What about the girl? Is she awake yet?"

Annabeth did not tense up. She kept on breathing rhythmically as if asleep.

"She is indeed awake. However, she chooses to let us believe that she is still sleeping. Younger minds work in stranger ways every decade, it seems."

Since she had already been caught, and since the voice had a gentle calmness, she allowed her eyes to open.

The scene before her was quite bizarre, with a gaggle of redheads and a few others her age, along with many adults, all pointing sticks at her.

"Is that supposed to be some sort of weapon?" she asked an old man with silver hair, the only one without a stick in his hand.

"Indeed Miss. Most of us are rather paranoid about security. But we aren't the guest here, are we? Will you grant us your name?"

"Clarisse La Rue," she lied without any hesitation. Names had power.

"Miss Rue?" She nodded, "We are part of a group of people who have been in hiding since centuries due to having special abilities. Your skills, specifically your ability to see that whom we call Dementors, is part of the special ability we possess. And yet you aren't one of us. Who are you?"

Annabeth went with the classic, "You won't believe me if I told you," as she wiggled her hands to feel her emergency blade. Even that was missing. These guys were at least competent, she would give them that.

"And yet, it's the unbelievable which fascinates me the most, my dear. Living through so many years, I have become rather bored with the believable."

"I am a Halfblood." Make of that what you will.

"Indeed? Though I wasn't specifically asking for your parentage, but who are your parents?"

"Athena and Frederick Chase." Internally she smirked, externally her face remained impassive.

"Interesting. Which of them has magic?"

Magic, as in powers?

"Athena," she answered uncertainly.

But the old man had noticed her hesitation.

"Are you unaware of magic?"

She reluctantly nodded, they hadn't done any harm to her.

"What do you mean by the term 'Halfblood?'"

"A person whose one parent is mortal while the other parent is a god."

There was absolute silence in the room for a moment, and then—

"She's obvious making up stories, Headmaster. I still say that we should Obliviate her and then leave her by that river."

"She saved my bloody life!" A dark haired boy shouted from across the room, she could see him lying on a couch. "You will not play with her memories!"

That statement sent chills down her spine. They were capable of actually altering her memories itself. She immediately tensed up.

The old man sighed, and then spoke "I, and the rest of the Order, won't attempt to change or otherwise remove your memories in any shape or form. This I say by the word of Magic itself."

His body flashed a silver colour, and she could sense something flow through her skin.

"You have no need to be alarmed, Miss Rue. You saved my student, though in a manner which has never been seen before.

"Our society is suffering through a Civil War of sorts, that's the reason why we are so concerned over security.

"Now, if you may choose to answer, how were you able to kill the Dementor?"

"The what?"

"It's a creature which appears in the form of a cloak floating in air. I believe that you stabbed him with your blade, which is rather unique."

"That monster? Yeah, I stabbed it with my blade. Now can I get it back? And can I leave?"

"Please do. Feel free to explore the house."

The fact that he did not give her permission to leave the house was clear to everyone in the room.

"It has been found that eating chocolates eases the mind after a Dementor's attack, would you like to have a bite?"

He very pointedly tore the chocolate in two, and ate the first half while offering her the second.

"You know my name. Common courtesy states that you tell me yours."

The old man turned, and then said in a slightly mischievous voice, "Some call me Gandalf, Miss Rue. Others call me Odin. You may choose whatever takes your fancy."

"Fine, you win, I'm Annabeth Chase."

"And I'm Albus Percival Wulfric Brian Dumbledore."

With that, he turned on the spot and vanished in thin air.

So… magic. Now I can truthfully say I have seen everything.

The others slowly lowered their sticks, and the adults started to disperse. The teens continue to talk among themselves.

When all was said and done, she was left in a room with only a dark haired boy, the same one who had warned her of the powers of memory alteration these 'wizards' possessed.

"Uh…" she trailed off, not knowing what to make of the situation. It was very decidedly bizarre.

"You are a prisoner here as much as I am."

That was unexpected.

"Why?"

He laughed bitterly, "For my 'security' of course."

She glanced at a clock hanging on the wall. She was sure it was more than 2 centuries old, but still somehow kept the proper time.

"Trade stories? We both saved each other's life, so it only makes sense that we get to know each other."

He scowled, but then said.

"I'm Harry Potter, and you're Annabeth Chase, yes?" At her nod he continued, "Well, it all starts from before I was even born…"

For some reason, that statement only caused her to think of the Great Prophecy, and inevitably about Percy.

As the story continued, se was sure she had found Percy's brother or cousin.

She could easily spot places where he was understating the danger or how good he was, just like Percy.

Annabeth was sure, that if they both ever met, they would either be the best of friends or the worst of enemies.
