Background Story:
Tobias Snape had seemed the ideal man, hook-nosed but not revolting, powerful by muggle standards, and fairly well off. However, his union with one Eileen Prince revealed another facet of his personality, a temper stoked by fear that made itself known shortly after she revealed to him that she was pregnant, though it was not until she'd birthed young Severus and the boy was revealed to have inherent magical abilities (something of which Tobias had not been aware of in his wife) that he began drinking and the shouting matches between the two began, leading often to violence.

Right up until the time Severus attended Hogwarts, his mother taught him little snippets, gave him books that would allow him to excel in secret until he could be sent off to learn all that he could..and in that time and the time during Severus' attendance of Hogwarts, Eileen learned obedience and the ability to cower in corners as Tobias became ever more violent, and Severus learned to become indifferent to all that went on around him, taking to ignoring his mother's cries and his father's shouts.
-----
Then came Hogwarts, a place of further torment. Nicknamed Snivellus by 'The Marauders' a group of what Severus liked to think of as delinquent Gryffindors led by the Potter/Black duo James and Sirius, he found himself often humiliated and ridiculed. Hexes abounds found their way to him, and he learned of death.

His first brush with suicide however was to be his last, for as the lank, greasy-haired teen had lain bleeding one night in one of the towers, he was happened upon by Lucius Malfoy, the regaled Prince of Slytherin, who made as to take Severus under his wing, to introduce him to his followers, and who eventually brought about his turn toward the Dark Lord, as well as that of many others.
-----
Years of terror and pain ensued. Torture, rape, more than he'd expected to say the least, and in each muggle brutalized, each slaughtered, he saw his mother, cowering, being beaten again and again by her abusive and domineering husband until he'd beaten the life out of her. He saw the faces of the dead at night, heard their cries and their whispers, endured their damnation as those around him seemed not to, and all the while he continued to pull forth knowledge, to drown in it, to use it as an escape and to make himself useful to the Dark Lord in a way that would not so often lead him into those brutal hunting parties.
-----
Then came the capture. The Dark Lord lay defeated, presumably dead, his followers being rounded up and sent off to Azkaban to meet the dreaded Dementor's kiss and as Severus awaited his turn, he found himself a Savior, traded information for a different kind of servitude that allow for far more freedoms and spared him from such a horrid fate, he found Albus Dumbledore and took the offered job as potion's master and has held it ever since, though he longs for a job as DADA professor so that he might teach

Copy of my Professor Application: (just in case)

Name of Character: Severus Snape
Why you'd be suited to play this character: I do believe we've gone over this already..it's an issue of muse and mine happens to like playing Draco, Severus, and Hermione.
Working Style: Strict, no-nonsense - features many point deductions for idiotic mistakes. (in true Snape fashion)
Sample Post:
The light of the torches did little to illuminate the greasy haired bat of the dungeons, as so many had taken to calling him year after year, yet the shadow they cast was an imposing one and, although unnecessary, it would suit his purposes quite well should any little peon get it in his mind to disturb the grading process that he was now undergoing. Ah, and what a painstaking process it was.

The essay of four lengths of parchment that current stared back at him bore nearly all of the mistakes of its predecessors, foolish mistakes that would not be tolerated in the least judging by the plethora or red inked marks adorning it and the slowly dwindling supply that lay in the ink well to the parchment's left. Foolish, the translation of which was stupid, and he did wonder, as he had a countless number of times before, what it would take to get the information through their thick, incompetent little skulls. In all truthfulness there were several students of the higher years who'd improved, and those few, like Granger, Draven, and Zabini who'd not needed improvement. It was their papers that always managed to lessen his headaches and feel, if only momentarily, that he might be getting through to them, that the subtle arts of potion making were at least being soaked up as they were revealed...but those moments were always short lived at the very least, and he always found some reason or another to nick a point or three from even the papers of his top students.

As it was, the parchment before him now was by a first year Ravenclaw with more book sense than actual wits if this paper was any indicator, but with those of their house, such was to be expected and thus, with the shake of his head and something akin to a skowl, he marked through it and quickly replaced it with another, wanting to finish with this tedious process sooner rather than later, but it was simply not to happen tonight for, as he moved to mark off a point for a well intentioned Hufflepuff's mistaken spelling of 'Hypethecomus' spelled on the paper 'Hypothecamus', a bolt of sheer gony shot though his arm, trailing downward until the a burning encompased the entirety of his arm. The Dark Lord was calling.

The quill fell from his hand, landing on the parchment and leaving a splotch of ink where it had fallen, and as he moved to grab his cloak for the meeting to come, the inks began running its way down the page, giving it the look of a well of blood running out from a deep gash, a bad omen if ever there was one, and one that went unnoticed. Likely, if he'd seen it, it would have gone unheeded as well.
