AN: Another story! A slash again, as I seem prone to writing lately. But this time it's a little different. Its Harry/Draco/Severus/OC. My OC character is a girl so there is no MPreg in this story. Warnings: violence, explicit sexual content, coarse language, established gay relationships. If you have any questions about the new species I made up, don't hesitate to ask. But be warned that I won't give anything away; if your question will be answered by the next chapter you will have to wait. But most info for them is given here. Oh and since I don't want to actually say the other creatures species in the story I will tell you now. Harry is a Light Elf, Draco is a Veela, and Severus is a Light Vampire. If you really want their species (my versions of course) explained in detail, ask in a review and I shall give detailed descriptions in the next chapter. So, read, review and enjoy!

Chapter 1: Inheritance

It was exactly one minute until her birthday. The slim girl sat by the window, staring out at the star filled sky. Her light brown hair shone in the darkness and her eyes glinted like sapphires. In less than a minute, now, she would be sixteen. And she would now if she was a Lithra, or not. See, Lithra genes are recessive and only show if a person inherits the double recessive form, one from each parent. This girl, Jessie Kirkwood, had what were called Lithra carriers for parents. This meant that her parents both carried the Lithra gene but it was overshadowed by the dominant non-Lithra gene. It was possible that she had inherited the recessive genes from both her parents.

If that was the case she would come into her "inheritance" the moment she turned sixteen.

Ever since her parents had told her that she could be a Lithra she had done extensive research. What intrigued her most was that she was going to have three mates. It was common for magical creatures to have more than one mate, but it was usually a range of one to whatever or two to whatever. But all Lithras had three mates. And after she turned sixteen only her mates would be able to calm her down when her powers got out of hand. And that happened a lot, because she would have control over all the elements as well as wings and a tail. The elements would react to her emotions and Lithras were very emotional creatures. Only her dominant mates, for she would be the fully submissive in the relationship, no matter what, would be able to calm her down.

She checked her watch, 30 seconds now. She ran her hand through her hair, her breath quickened. She really wasn't sure what to expect. That was one thing her research had come up dry on. What was about to happen was a complete mystery. She check her watch again, here it was, the countdown.

Ten…Nine…Eight…Seven…Six…Five…Four…Three…Two…One…

And everything went crazy. Rain beat down. Thunder boomed. Lightning flashed. The earth and the air trembled. The fire in the hearth blazed. And Jessie screamed, an ear-splitting scream. Pain and emotions coursed through her body. She fell to the floor, her body flailing. Three faces appeared in her minds-eye. First, a pale, black-haired man, with a hooked nose. Then, a pale, blonde boy, with silver eyes. And finally, a dark-haired boy, with emerald green eyes and a lightening bolt-shaped scar on his face. She knew, both instinctively and from her research, that they were her three mates. She quickly figured out who they were. They all went to Hogwarts, or actually, were at Hogwarts, since on of them was a teacher. Strangely that didn't bother her; he was her favourite teacher anyway. They were Severus Snape, Draco Malfoy, and Harry Potter.

The pain she was feeling made her barely aware of her parents running in and placing her gently onto a couch. Her parents heard her muttering the names of her mates over and over again. They were shocked.

Meanwhile, in the headmaster's office at Hogwarts, the headmaster was with the Lithra's three mates. Draco and Harry were cuddled together on an armchair and Severus was pacing back and forth in front of the headmaster's desk.

"She has just come into her inheritance." He said, then the room shook, outside a storm raged, "Oh Merlin, she's a Lithra!" The headmaster looked up.

"Ah, yes. I recall a girl was removed from the school tonight, because it is her sixteenth birthday and they had suspicions she was a Lithra."

Severus stopped.

"Jessie Kirkwood was removed from the school tonight?" He asked, his tone dangerous.

"Why, yes, that's her. She must be your mate, give me a moment to contact Kirkwood Manor." Dumbledore said and turned to his fireplace.

Back at Kirkwood Manor, Mr. and Mrs. Kirkwood were trying to soothe their very emotional daughter. Mrs. Kirkwood looked up as she heard a rustle in the fireplace and saw Dumbledore's head.

"Albus! Thank goodness! Do you know where we can find her mates? She keeps muttering their names but we dare not leave her to find them." She said, scurrying closer to the fireplace.

"Yes, I have them with me. May I send them through?" He replied.

Mrs. Kirkwood nodded vigorously, "Please do!" She said.

Dumbledore's head disappeared and moments later Severus, then Draco, then Harry, came through the fireplace. Severus ran directly to Jessie, who reached towards him.

"Sevvy." She whispered hoarsely, calming down immensely. He wrapped her up in his arms and the storms stopped. So did Jessie's pain and she breathed a sigh of relief, leaning into Severus's chest. He stroked her back soothingly. Draco and Harry came forward more tentatively and reached for Jessie's hands. She smiled up at them both and they smiled back.

Severus looked up at Mr. and Mrs. Kirkwood.

"We'll take her to our new rooms now. You have no need to worry about her anymore, she will be absolutely fine."

They nodded. Severus picked up Jessie and, with Harry and Draco trailing behind, disappeared into the fireplace. They flooed directly to their rooms and Severus set Jessie down on the huge bed. They all got themselves ready for bed, then snuggled around her. Jessie's last thought before drifting off into a peaceful sleep was that that had been some inheritance.
