Italicised words are thoughts.

While the battle was raging on a lone figure slipped under the remains of the Whomping Willow, and into the shrieking shack. She spotted the body of Severus Snape leaned against the far wall covered in his own blood. Oh Merlin, he looks worse than grandma said he would, she thought, how am I supposed to heal this? The woman pushed her cloak's hood down and set to work. She started by cleaning the blood off of him. Once she got a clear view of his wounds, she checked for a pulse. She had seen the Golden Trio leave so they obviously thought him dead. She smiled to herself when she felt one minuscule tremor in his jugular. She then rummaged in his robes for a bezoar. Upon finding one (as she should have, he's a bloody potions master for Merlin's sake) she forced it into his mouth and massaged his throat to help him swallow it. After she stopped the bleeding and closed the wounds she slipped a blood replenishing potion down his throat and cast a modified rennervate to get his blood flowing. As soon as his pulse became regular and his breathing was less shallow she tucked everything into her cloak and apparated herself and Severus out of the shack and to a small cottage on a mountainside leaving behind nothing more than a faint glimmer of sidhe magic.

Two hours earlier

Emiryssa Silverthorne was woken up by her grandmother, Thistle, shouting her name. She sighed and put her dressing gown on before heading downstairs to see what all the noise was about. She pulled her long dark brown hair into a ponytail while she bounced down the stairs two at a time, a habit that her grandmother hated. When she reached the bottom of the small flight of stairs she was welcomed to the sight of her grandma pacing and glowing. To anyone else this would have looked terrifying, but to Emiryssa this was simply another day living with her sidhe family members.

"What is it grandmother?" the 28 year old half-sidhe asked her groggily.

Her glowing grandmother turned and looked at her, "The final battle has begun!"

"Yes, and it has nothing to do with us. The ministry is against half-breeds, why should I rush to their aid when, had our roles been reversed, they wouldn't show me the same courtesy?"

"Because it's not the ministry fighting and dying, it's the children and professors." The deep baritone of her grandfather's voice gave Emiryssa a start.

"Oh, Grandfather, you startled me, you really ought to start wearing a bell or something, you- THEY'RE LETTING CHILDREN FIGHT A BLOODY WAR?"

Her sidhe grandfather nodded sombrely.

Emiryssa's big emerald green eyes flashed angrily. She had always loved being around and caring for children and the thought of the ministry not even bothering to help fight a war while children were fighting, dying, and watching their friends and professors die at the hands of heartless killers made her want to vomit. While she was only twenty-eight, she had endured things that would horrify some death eaters, and her experience made her extremely protective of the latest generation. She was shaken from her thoughts as her grandmother placed a hand on her shoulder.

"Your old mentor, Severus Snape, is in grave danger." Thistle said.

This really got Emiryssa's attention. "Professor Snape? What do you mean he's in danger?"

"You must go to him, when you find him, heal him and bring him here."

Emiryssa ran up to her room. She put on a cloak over her dress and placed an undetectable expansion charm on the pockets and began stuffing various healing salves and potions in them. Once she got everything she grabbed her wand and made her way outside to apparate. Before she left her grandfather pulled her aside and into his study. He reached into a desk drawer and pulled out a pair of silver daggers that were inlaid with small diamonds and emeralds.

"They were your mother's," he said as he handed them to her.

She started tearing up and took them from him. "I'll make her proud," she whispered before running out to the gardens to apparate to Hogwarts.

She appeared in a field of chaos. There were spells flying everywhere and at first she was almost hit by a few of them. Once she regained her senses she began firing rather nasty hexes at various black clad masked assailants. She made her way to the castle to wait for her grandmother's instructions. When she got there she saw Augustus Rockwood raise his wand toward Fred Weasley. Before he could utter whatever twisted curse he had planned for the twin Emiryssa's dagger was sinking into his throat. The twins turned to stare at her.

"You can thank me later," she said with a wink and smirk.

Stay in the castle for now, her grandmother's voice echoed in her head, I will alert you when it's time to go to him. Emiryssa nodded even though she knew her grandmother couldn't see her.

As she wove her way through various duelling parties she put her daggers in a holster on the belt of her dress. She took out her ebony wand once more and began duelling with random death eaters. She narrowly escaped more than a few avada kedavras and several crucios. After a while she got tired of using her wand and just fought wandlessly, throwing her opponents into walls and staircases. She caught the eye of Lucius Malfoy and he came over to her. He didn't have a wand and her grandmother had told her a few days ago that he and his family were no longer supporters of Voldemort. She winked at him and knocked him out wordlessly. At least now no one can say he fought, Emiryssa thought. Breathing deeply, she began to clear her mind, while taking care of Malfoy she sensed her grandmother was trying to contact her.

What is it grandmother?

It is time. Go! Now!

The last few words were shouted and Emiryssa felt a headache threatening to bloom. Using occlumency she pushed the pain back and made for the exit. Once she was out she cleared her mind once more.

Where do I go?

The place he fears most, whose entrance lies under the tree.

Emiryssa rolled her eyes as the connection broke. Thank you grandma, this really is a great time for riddles, she thought sourly. She tried to think, from what Severus had told her during her apprenticeship he had almost been killed in the shrieking shack by Remus Lupin while he was a student at Hogwarts. Well I'd be afraid of the place after something like that, and the entrance is under the Whomping Willow! I've got it! She broke out into a run and headed for the Shrieking Shack. While she was running she heard her grandmother's voice one last time.

Be prepared Emiryssa! His wounds are great and not for the weak-stomached!

Emiryssa chuckled at her grandmother's words. Anyone who knew her knew she wasn't squeamish at all. While she was learning under professor Snape she had made numerous potions for the infirmary where he brother was apprenticing for Madame Pomfrey. She had been able to observe the nastiest wounds she had ever seen up close and she hadn't fainted or vomited once, in fact sometimes Severus would have to drag her out of the infirmary just so she could get her own work done. The gore of it all fascinated her to an almost morbid extent. She still took heed to her grandmother's words though, while she could easily handle seeing a stranger in pain, she wasn't sure if she could bear the sight of her former superior in agony. She pushed her thoughts out of the way, knowing she needed a clear head for the upcoming task. Professor Snape would have my head if I didn't, she thought with a chuckle. She ran up to the remains of the Whomping Willow, not knowing what to expect.

Present

Emiryssa crash landed outside of her grandparents' cottage. The home was quite a ways away and she had to enforce her apparation with sidhe magic. She managed to levitate Severus' body into the house before fainting from sheer exhaustion.

A/N: I had to save Fred, he's my favourite twin :3

Oh! And Grandma Thistle isn't a seer, she just knows when things are happening, or are being planned. More on that in chapter three, first we need to get Severus healed.
