Ria glared outside. She hated the snow. She hated the cold. Whoever thought that living in a place that had winter was crazy. Why did she have to go out in the snow? She would be perfectly happy if she never had to again. Maybe she could hibernate.

Drae laughed at her friends expression. "Come on Ria. It's not that bad." She said trying to convince the lioness to go out and join Adrian and his housemates in a snowball fight.

Ria looked at Drae and raised an eyebrow. A perfect pureblood expression. "Do you have any idea what you just said? Or have you inhaled any potion fumes lately."

Drae rolled her eyes. "Well I could sit here and say that you've inhaled just as much as I have. But I'm not. Now if you don't mind I'm going outside and have fun building a snowman! If you feel like getting over your ridiculous fear of the cold you are more than welcome to join me. You can even wear gloves."

"You never denied that you did." Ria said turning the page of her history book. "And I am cold sitting right here. I am not going to go out and get even colder."

Drae cocked her head - a habit she had picked up from her mother. "Are you feeling alright? Because you shouldn't be feeling cold with all the warming charms in the castle."

"I think I just have a minor cold," Ria said dismissively. "I'll get over it."

Drae shook her head. "Fine but as soon as I get back I'm taking you to Pomphrey."

Ria looked up at Drae, "Why?"

Now the Slytherin was worried. "Because even if you have a cold, you shouldn't be this cold. That has nothing to do with a virus. And I'm your friend, I'm worried."

"Alright," Ria sighed. "I'll be waiting for you." She said.

Drae smiled and ran outside immediately pelting Adrian with several conjured snowballs.

Ria watched them. Drae did have a point, but it was just a cold. Turning back to her book the words started to blur. She was tired, maybe she should get some rest.

~Thirty minutes later~

Drae laughed and waved to the Hufflepuffs, they were headed towards the Black Lake to see if they could skate on it yet.

She walked over to where she left Ria.

"Okay Ria. Let's get you to~" She stopped. Shocked. Ria was sprawled on the floor as if she had collapsed there.

Adrian - who had decided to follow Drae after she told him she was worried about Ria - saw what made Drae stop. he turned to the Slytherin girl. "Stay with her, See if you can warm her up. I'll go get the Headmaster!" he said running to Snape's office at a dead sprint, taking as many shortcuts as he could.

Snape looked up and took in the sight of the panting Hufflepuff. Standing up he followed Adrian without a word. When they reached Ria, Snape could clearly see something was wrong.

"What happened?" Snape asked kneeling by the Gryffindor girl. She was icy cold to the touch and shaking in her unconscious state.

Drae looked at the Headmaster. "She said she felt cold. She brushed it off as a cold. I told her I would take her to Pomphrey as soon as I came back inside. I found her like this then Adrian went to get you." She said in a choked voice.

Snape levitated Ria and rushed her to the Hospital Wing. He had an idea what was going on, and it wasn't going to be pretty. Since Ria was half Lunar Elf if her other half became weaker her elven blood would attempt to get rid of it in order to make her stronger. But that usually didn't happen with human blood. Severus swore in his mind. This was not what he signed up for when he took the post as Headmaster. He set her down on the Hospital bed and then began running diagnostic and identification charms. What he found shocked him. Ria was half Naga. That would explain a great deal.

"Get out," He told the students that had followed him and shut the doors before summoning the potions Ria needed. It was just like what had happened with Tom~

Snape cut himself off. It couldn't be possible, it just couldn't.

~Flashback~

Tom writhed on the bed snarling. His Naga blood was trying to kill off the human blood in his system. Arching off the bed Tom bit his tongue and clawed at the bed to keep from screaming from the shear agony running through his veins. He pressed one scaly finger to his arm and called Severus to him. Something had gone wrong with the ritual. He felt Severus come into the room and the shock radiating from the other man. Tom would have rolled his eyes if he had less self control, or had been able to focus on something else besides the pain.

Severus didn't know what was going on and was going to panic. Casting every charm he knew to find out what was going on Severus never expected that his friend had Naga blood in him. The fact that it was fighting his human blood. At the moment the Dark Lord's Naga blood had already consumed half of his human blood. If this went on any longer then his Lord would become a full Naga.

Severus froze when he felt one of the spells tell him that the Dark Lord was now a full blooded, pure Naga. The Dark Lord's body shuddered as his skin lost its scaly appearance and his hair began to grow. But what shocked Severus more than anything was when the Dark Lord's legs fused into a long muscular snake like tail. The Dark Lord lay panting on the bed, shivering from the sudden coldness that the loss of his warm blooded human side had caused.

"My Lord," Severus said at a loss. The Dark Lord's red eyes turned to regard Severus tiredly. Severus approached his friend and knelt by the bed, for once completely at a loss for words.

"You know that you can call me by my name, Severus." Tom said tiredly. His entire body ached. Severus placed a hand on Tom's.

"Tom, are you alright?" Severus asked.

"I feel great," Tom said lightly. "Of course I'm not alright, I feel like I was thrown against the wall." Tom paused and grew paler. "Wait a minute, I can't feel my legs." He turned to Severus. "What's wrong with my legs?"

Severus hesitated. "You don't exactly have legs anymore…" He said. Tom sat up with wide eyes. "You have a tail." Tom stared at his tail. It was long with a white underbelly and a black back with a red design on the back of his tail. Rather beautiful, but at the moment he didn't really notice. Tom took his wand then tried to split his tail. It didn't work on his tail, but it worked on Severus beautifully. Severus dodged and the entire left half of his robes were shredded. His arm was bleeding lightly, but considering the strength of the spell he got lucky.

"It bounced off," Tom said staring at his tail. "Why do I have a tail?!" Severus sat down on the edge of the bed.

"I need you to calm down," Severus said slowly. A panicked Tom was never a good thing. "Then I will tell you what I found out in Slytherin's library." Tom calmed down. Since they were in Slytherin's castle he was safe and could take time to figure out what was going on.

Once Severus believed that Tom had fully calmed down he began to explain. "In one of the books I found while researching the Slytherin line it said that Salazar Slytherin was a pure blooded Naga." Severus said slowly. He waited for the information to sink in. "It reacted worse than expected with the ritual, but there will be no lasting effects."

"Will I be able to change back to a human?" Tom asked looking at his tail.

"Yes," Severus replied.

~End of Flashback~

Drae gaped at the doors of the Wing. Shocked that Severus would just slam them in her and Adrian's faces.

Adrian - who had finally caught his breath - placed a hand on the Slytherins shoulder. "Come on Drae. You know he'll tell us if anything changes." He led her over to a bench near the doors to the Hospital Wing and wrapped an arm around her, trying his best to comfort the girl.

Suddenly a voice echoed through the halls of Hogwarts. "This is a broadcast from the Ministry of Magic," a sickenly sweet voice said. "All students will have to take a blood test to determine what blood they have and all students with creature blood will have to take separate classes in order to keep the wizarding community pure. Have a great day."
