Chapter 1: I Fall Out of The Sky

Andromeda's POV

The story that I was told about my birth is one about revenge at the hands of my father, much like King Mino's punishment at the hands of Poseidon. One of the things that you must know about the gods, try and out wit them, you'll always lose. Lord Hades was so furious that Tom Riddle had outwitted him that he went and had sex with my mother, who was in Azkaban. I was born and then taken, by the Furies, to live in the Underworld until I was old enough to go to Camp. I've been on dozens of quests, but nothing could compare to what would happen to me next.

I was on the Argo II, to help Percy and the others, when the Roman wind spirits appeared. Everyone hung onto something, but I was blown away. I could hear Percy and Annabeth screaming for me, calling out my name, but I was soon lost in the night. The winds didn't let me go and before I could get my sword out, they threw me into the sky. I could hear them laughing as I fell.

A huge castle appeared and I found myself falling through an opening. Suddenly I heard screaming as I did the one thing that would keep me from joining those in the Underworld. I shadowed myself to the floor. Of course I mistepped and heard my ankle breaking. Really, just great! Suddenly everyone screamed in horror. Hello, my ankle is damn broken here.

"SILENCE!" came a man's voice.

Everyone stopped screaming. Wow, was this man related to dad?

"Broken…ankle," I managed to say.

"Minerva, hold her down," he said and he did something because my ankle was back in place. "Get Poppy!"

She nodded and then left.

"Who are you?" I asked him.

"My name is Albus Dumbledore," he said.

"Never heard of you," I told him.

Well that was actually a lie.

He smiled at me and then asked, "And what's your name?"

"Andromeda LeStrange," I told him and his eyes widened.

"You're a Lestrange," he said.

"I guess you know my mother," I told him. "Yeah, I'm her daughter. Half-blood!"

I said this because my father had told me that Hecate's world cared about blood status. Don't ask me why, sounds like something out of Nazi Germany if you ask me. A woman suddenly appeared, wearing all white.

"Get Miss LeStrange to the Hospital wing," he told her.

"I don't need any medical help," I said, "Just give me the stuff in the bag."

"I'll be a judge of that," she said.

"I know what I'm talking about," I told them. "Just give me the stuff that's in the bag and bottle."

He pulled out the godly medicine that everyone had packed and I started to scarf down a little more than I should of. Feeling feverish, I closed the bag. A golden light surrounded my ankle and I felt the swelling go down.

"Amazing," he said.

"Thanks! I might not have the healing powers that my cousins have, but I do well for myself," I said.

"Can I, at least, make sure that she's fine," the woman said.

"Sure," I said and she took out her wand and started to wave it around.

She didn't say anything, but I could feel her magic covering me. When she was done, she said, "I don't know what she took, but her ankle is healed."

"Thanks for letting me know," Dumbledore said. "Well it seems that your fall didn't have any lasting-."

"Andromeda!" a girl suddenly called out and I looked to see Ginny Weasley, daughter of Ares, standing there.

"War girl, what are you doing here?" I asked as she almost tried to knock me off my feet.

"I got to school here, dead girl," she said.

"I wish you wouldn't call me that," I said.

"Hay, at least it's not Seaweed brain," she pointed out.

Good point.

"It seems that you know each other," Dumbledore stated.

"Wondering how that's possible," a man that looked like Thanatos commented.

"We go to camp together," Ginny said. "She's my cousin! HAY, LUNA, ANDROMEDA IS HERE."

"Luna is here," I said.

"Yeah!" she said, "Shocked!"

"Kind of," I remarked.

A girl wearing black robes with a Ravenclaw crest ran over and gave me a hug. She smiled widely and I thought that maybe this wouldn't be too bad.

"I thought you were going to Greece," she said.

"Long story," I told her.

"Excuse me, but cousin," Dumbledore said.

"Yeah," they said at the same time.

"It's official, Miss Weasley has some strange friends," he said.

"Got a problem with that," Ginny snarled, "Because if you do, Professor, I'll ram a spear into your stomach."

"Ginny," I said and Luna rolled her eyes.

"Why you little-."

"She's got a spear," I warned him.

"So you both knew that Bellatrix has a daughter," Dumbledore said.

"Yeah, so," Ginny said.

"Need I remind you, Miss Weasley, her mother killed scores of people and caused the Longbottom's to go insane?"

"And that's, like, her fault," Ginny said, "It's not her fault that her mum is a killer. Just like it's not my fault that my family is poor."

"Point taken," Dumbledore said.

"So how are things in the other place?" Ginny asked, making a veiled reference to the Underworld.

"A mess," I answered.

"It's always a mess," Luna remarked.

"Miss LeStrange, would you like to come and continue your education," Dumbledore asked me.

"Headmaster, you're not serious?" a woman asked, "Putting this child within reach of children whose parents her mother killed."

"You smell funny," I said, catching the smell of a monster.

"I don't smell funny, you little brat," she snarled.

"The rules are simple," Dumbledore said, "Any child born with magic can come."

"And we'll show you around, make sure you don't get lost," Ginny said.

"Thanks and I would like to come," I told him.

"But-."

"Miss Weasley, take her to my office so that she can be sorted," Dumbledore said, "Everyone else, lets continue our feast."

I saw everyone looking at me as my cousins led me out of the hall.
