Potter Manor
"I, James Charlus Potter, Lord of the Ancient and Noble House of Potter hereby disown Eris Potter and from this day forth she shall not carry the Potter name. So mote be it." thundered James Potter.
"So mote be it," a small voice said. The speaker was Eris Potter, the unloved and forgotten Potter. Her brother, the Boy-Who-Lived, was the saviour of the Wizarding world. She was an afterthought, always in the shadow of her twin brother. She wished that the Halloween night never happened. Well, she would have been neglected anyway. James had always wanted a male heir - which he got, but received Eris as an extra.
It was the summer holidays after Daniel's 8th birthday party. She had been so jealous when she saw a snitch covered cake with written in cursive icing, 'Happy Birthday Daniel!' That set her off. It wasn't her fault that everyone ignored her and her parents probably even forgot when her birthday was - clue, she was Daniel's twin sister.
Present time
The small girl was lying at James' feet and he was towering over her, his face red and a vein on his forehead was bulging. Her black hair was hanging limply down her back, her green eyes glowing an eerie shade of green. Lily was hanging around in the shadows, watching the scene unfold but made no move to help her so called daughter. Daniel, however, was standing at his father's side obviously enjoying the fact that his filthy sister was being disowned. James told the wards to never let her in again and in a flash, Eris previously Potter was gone. She disappeared from the Wizarding World for a few years but no one made a move to look for her for a long time.
Eris POV:
Stupid family! How dare they! She would get revenge, but good things come to those who wait. I disapparated goodness knows where. I opened my eyes, I was in a wood. This announced danger. Suddenly a huge dog with glowing red eyes emerged from the shadows. I screamed. O My God! What was this horrid monster?! I kept calm then felt a surge of anger. I felt my body burning and when I looked at my body, it was burning in black flames. What the hell? I fingered my bracelet and it turned into a set of pitch black knifes. I stuck them into the monster's body several times for good measure. Then I recognised it as a hellhound from my many Greek Mythology books. From what the creature was, I guessed that Greek Mythology was true and the gods were true. My guess was that I was a demigod, half god, half human. Well, it wasn't surprising, I always felt stronger at night and had weird black wisps around her. I scared people namely Ron Weasley and her brother, Daniel.
Shaking myself out of my memories, I walked. I wandered around, with no idea whatsoever where I was or why I apparated here. I drifted around for a long time. I had lost count after 30 days. I tested out my new powers and found out that I could travel by shadows and became stronger at night. I began to feel a bit faint from hunger and dehydration when I saw a sign just 10 metres in front of me just as I felt someone's presence behind me. I whipped round and took my knives out. Turned out, I did need them. Three huge men with ONE eye instead of two were looming over me. I slashed and hacked with them. I took self-defence classes to help with my stamina for duelling which fighting with a knife was similar except I use a knife instead of my hands and legs. I wasn't the best at self-defence so the Cyclops got a few hits on me. It was so strange because they turned into gold dust when they died. Oh well, you could expect anything in the Ancient Greek world. I realised my injuries were a teensy bit worse than I thought they were, when black splotches filled my vision. I managed to say shit before blacking out.
Percy POV:
I was walking around camp when I felt a strange presence. I couldn't feel inside camp so I headed outside. Turns out, it was a good idea to go out because a new girl was fighting THREE Cyclops. She had long black hair but I couldn't see her face because she was facing the Cyclops. Her moves were graceful but she wasn't good enough to escape the blows. She delivered the deathblow on it but fell to the ground immediately. Maybe her injuries were worse than he thought. I saw a glimpse of glowing green eyes before her eyelids hid them. What a shame... Her eyes were a captivating green but spooky. I picked her up. She seemed a bit too light to be healthy. I glanced at her and could see her ribs jutting out of her skin and her eyes were sunken into her face. Definitively not good. I carried the mysterious girl to the infirmary, many people staring at the new girl. When I arrived there, I saw that Chiron had already been alerted. He stared at her skinny form in concern. A healer from Apollo sent us out while he tended to her wounds. He came out five minutes later saying that he healed the injuries but she would have to start by eating and drinking a bit because her stomach would not be able to hold much.
Eris POV
I woke up in a new place. I can't say that I was very surprised because I usually woke up in the forest wondering why and where I was. I glanced down and saw that someone had healed me but after checking my appearance in the mirror, I saw that whoever healed me couldn't take away the fact that I was only skin and bones. It was a relief to look at myself after such a long time outside in the wilderness. I peered out of the window and saw the sight of many kids from five to eighteen milling around, some sword fighting, others chatting. Must be a sort of camp for demigods... I was shaken out of my daydreams by a cough. I turned around and whipped out my daggers. Oops! The intruder looked a bit surprised. It was a boy about sixteen with sea green eyes. I figured he must be the son of Poseidon.
"Hi! My name's Percy, Percy Jackson, son o-"
"-yes, I know, son of Poseidon and this came is for demigods," I interrupted.
I must say, he looked quite surprised that I knew all this stuff but... He left my side and went outside. I sneaked behind him cause I'd figured that he would be speaking to someone about me.
"Chiron, I don't know how but the new girl knows about the gods and demigods. She's so young and I think her family dumped her..." said Jackson urgently to someone.
Aha! The famous Chiron, trainer of Hercules, taught here! And he was a centaur... Well, at least I got something out of eavesdropping on their conversation. I decided to scare them by shadow travelling in front of them. It was so fun! They looked so shocked! Then I heard a horn blow. "Yay! Dinner!" I cried, and ran off. Ha! Served them right.
