Magnolia Crescent 02:54 A.M.

Severus gathered his robes around him, sheltering himself from the biting cold of the night. The chilling winds caused the hems of his cloak to puff out making him appear as a spectre. He cursed the meddling old fool once more for good measure. Not even Potter should be able to make a big a mess of himself to deem Severus needed to be out in this weather. He steeled himself against the gale and purposefully strode around the corner and into Privet drive.

As he stepped forebodingly closer to his destination, his enhanced smell picked up something he never thought he would have in his entire existance. Seraphim blood.

Severus knew of course about the many rumours of his vampirism that circulated through the student body of Hogwarts and they weren't entirely false. No he wasn't a vampire. He was one of the Kerubim. One of the fallen. Contrary to many beliefs that they were 'cast out of heaven for following Lucifer' they weren't. They were born this way and were the offspring of a wizard and an Angel. They did however have vampiric characteristics and that of enhanced smell was what was driving him insane.

Tracing this heavenly scent, Severus found that it in fact came from his destination, 4 Privet drive. Of course it did he thought to himself and it just had to be Potter didn't it. Did he not have enough, the fame the fortune the adoring fans. No. He just had to have the honour of being a bloody Seraphim as well.

That however brought him out of his trance of hatred. Bloody Seraphim. It was the blood which had made him notice the scent. 'Oh immortals' he whispered, Potter was a Seraphim, Potter was bleeding, and the Angel inside of him was calling to Severus' Kerubim to save him. That was why he could smell it. That was why he had never thought Potter to be a Seraphim before during those tedious years spent teaching.

Snape collected his thoughts and stalked to the door of No. 4 with a new vigour. He furiously rapped on the door, not caring that it was 3 in the morning. He kept knocking insesently until he heard a thundering down the staircase that sounded like a caged herd of elephants. The handle was turned and Severus saw a beach ball of a man with a betroot red face standing in the doorway looking ready to explode.

'Who the hell are you and what in the blazes of the seven hells are you doing here at this blasted time in the morning?' He demanded, trying to keep himself from roaring directly into the suspicious figure's face. 'Severus Snape, potions master of Hogwarts school of witchcraft and wizardry. I'm here to check up on Mister Potter, as I am informed that an incident occurred here this evening and I must sort it out, so to speak.'

Vernon Dursley's face was suddenly drained of all colour and when he spoke almost all sylables trembled with uncontrolled rage. 'There is no mister Potter here sir I don't know what you are t-talking about.'

'Look Dursley' Severus calmly said whilst stepping round Vernon into the house 'You don't want to play this game. I'm done with pleasantries and I need to know where Potter is.'

'I-I'm not scared of y-your type, you're all f-f-fre-eaks.' Vernon stammered.

'Not scared are we? You really should be. You don't know who I am. What I am and What I am capable of Dursley. Now if I were you, I'd go fetch Potter right. this. second.' With this last threat he bared his fangs, just enough for Vernon to see them.

With that warning Dursley scrambled to fetch the back door key and proceeded towards the glass french doors, out of which he could just see a huddled form of a boy, tucked beneath the hedges, where Harry had managed to drag himself to before he had seemingly collapsed.

Severus had followed close behind Vernon when he had seen the general direction that the despicable muggle was headed. He had to stop himself from gasping in shock at seeing the body of the broken Seraphim.

Once the door was unlocked and opened, Snape had shoved Vernon out the way and run over to the bushes where Harry was hidden. 'No. NO. This can't happen. Harry you can't die, don't die on me Harry, you're the second bloody Seraphim, you can't die on me now. They'll both kill me. Dont. You. Fucking. Die. On. Me. Now. Oh gods, oh gods no. Don't make me do this.'

Severus brought his ash grey wings to burst out from his shoulder blades and curl round him and his protegee. 'I'm sorry Harry. I'm sorry. You'll hate me for this I know but you can't die. Not now.' With this Severus pierced the jugular vein in Harry's neck and drained him, before pricking his own wrist and forcing his blood down Harry's throat and into his system. Bringing his change into a fully formed Seraphim forwards.

Pain laced through Harry's nervous system and his back arched upwards as he silently screamed for release. A single tear ran down his cheek as he begged for it to stop. Severus nearly gave in when Harry opened one of his emerald tear filled eyes and whispered 'Please' then closed it again, blacking out once more.

At this Severus turned, saw Vernon there and growled at him before apparating himself and Harry to Prince Manor. Dumbledore couldn't find out about Harry's true nature, only the god's knew what would happen if Albus found that his weapon was even more powerful than he'd expected.
