It was in Harry's 6 year, when his life took a huge change it started when he was knocked out between classes. Draco was pissed off that Harry beat him the last Quidditch match so between DADA class and potion class he tried out a new spell he found in one of his dad's books "SANGUINEM EVIGILANTES!" (Blood waking) He shouts pointing his wand at Harry. The dark hair teen looks around just as he see the red light of the spell hit him sending him flying across the hall and out the window, Draco paled as he watched the stain glass window brake at the dark hair rival falling though "Oh no." He said running off after other students start looking at him.
Harry was in the hospital wing in Hogwarts, he was sat on the bed shivering at the normally warm room Madam Pomfrey was worried at this and did a few scans, Harry watched her face widen in shock and looked "What? What's wrong?" Harry asked starting to panic
"I don't know Harry ... I will have to get a someone in."
"Has Malfoy killed me?"
"No no you're not going to die." She said calming him as she walked away. Harry started scratching at hard bits of skin that started to appear on his arm, hands and by the time someone from St Mungo's come to the school and Dumbledore is called to the hospital wing the hard skin is around his eyes.
The Healer from St Mungo's did his own tests on Harry, frowning a little he shooed the headmaster away before sitting in front of Harry "Okay Harry do you know if anyone in your family were Naga's?"
"No." He said the Healer nodded as rubbed the back of his head
"Have you ever been bitten by a poisons snake in the magic world?" he asked
"Just a basilisk, but the Head Master's Phoenix stops the poisoning from killing me." He said, looking down into Harry's notes
"Could you already feel the effects of the poison?" Harry nodded as he rubbed his eyes, the Healer saw the teen's pupil have turned into slits, and he sighed
"Okay Harry I think I know what is happening." He said
"What?" Harry gasped moving forward, the older wizard smiled at him
"The Phoenix stopped you from dying stopping the poison in its tracks; you might have felt tried for a couple of days after words…" Harry nods "…right so you already had the Basilisk poison in your blood when he healed you. The spell that young Malfoy used is one that is used by dark wizards to awaken dormant creature blood in a person." Harry blinked at the man
"Are you saying that Draco fucking Malfoy had turned me into a Naga!" He yelled
"Well sort of you're not going to lose your legs or anything like that, you're just going to grow some scales and a few other things as well." He said the dark teen was shaking his head starting to panic
"W...What's going to happen to me? A…am I going to be kicked out of Hogwarts!" He cried out as he stood up
"No Harry they won't kick you out, relax."
"HOW CAN I RELAX I'M ALREADY HAVING PROBLEMS I DON'T…"
"POPPY!" The healer yelled as he tried to calm Harry down.
After giving Harry a sleeping potion they left the teen to sleep curled up under many layers of blankets and a heating spell Dumbledore stood there with Snape, Madam Pomfrey the Healer from St Mungo's and Mcgonagall "I want Mr Malfoy expelled." Mcgonagall said
"I don't think that is necessary." Snape said looking at her
"Severus he used a dark spell that he learnt from his father." She said looking at him, in all honesty Snape had nothing to say on that
"Severus I'm afraid the aruras have been called because of the spell he used." Dumbledore said, the dark hair man looked at him
"You're throwing Draco to the aruras for that pampered brat?"
"Pampered?" Poppy yelled, Albus looked at the Medwitch and tried to stop her from saying any more but she was having none of that "That poor lad is not pampered at the being of each year he has come to me with a glamour on and once it off…" she stops and takes a deep breath "That boy has been beaten more times than I've seen and each time I patch him up and tell Albus only to have that boy come back here hiding a broken ribs, black eyes, cuts!" She yelled waking the others kids in the hospital wing.
The other look at the headmaster waiting for him to say something, "Severus I need you to look for a way to get rid of creature gene." He said, the Healer snapped his head up at him
"You can't the spell that boy used has locked the snake blood with his human blood trying to remove it will kill him." He said, he was shocked that the head master would even say that
"Are you sure it will kill him?" Albus asked
"Yes!"
"Umm now we have a problem." He said
"Look here Dumbledore, that boy is going through a change that is terrifying he doesn't need your meddling what he needs is someone who cares for him if you can't give him then I will remove Mr Potter from this environment to somewhere safe!" The white hair wizard looked at the Healer
"Enough of this Harry is a sleep and will be for a long while." Poppy said
"I'm going to call Remus." Mcgonagall said walking away, Dumbldore looked worried and followed her out the hospital wing, Snape just stood silently looking at the dark hair boy on the bed
"Is he really beaten Poppy?" he asked
"Remember a boy about 5 years ago he was in your house, his father abused him."
"It's not that bad? Is it?" he asked
"Yes."
