Physical Description: Very tall, almost stocky, Snape has dark hair worn longish and perpetually greasy feeling. He has a distinctive odour, due largely to working with potions every damn day. Wears black. Smiles rarely.
Personality: Snape was manipulated throughout his life by Dumbledore - this is why he's still at Hogwarts, actually, as now that the man is dead he sees some hope that the school will be less manipulative, with students, generally Slytherin, singled out for specific blame for all ills. He continues to blame Dumbledore for the outcome of the Shrieking Shack incident, and believes (he's right) that things would have been different if he had not been Slytherin, unpopular, and not pureblooded, and Sirius Black his opposite in every way.
Bloodline: Pureblood, mixed English and Germanic-French ancestry
Background / Family History: His father was Rigellus Black, making him Sirius Black's half brother, while if anything is known about his mother, he isn't saying, other than that he respected her. Both parents are dead - how is unknown. Although he is technically pureblood, his illegitimacy makes him only slightly higher than halfbloods in the eyes of someone like Lucius Malfoy. This is one of the reasons he is seen by the Malfoys and Blacks as the Death Eater they can order around - they know his true parentage and aren't afraid to use it. He has now told Sirius, who told Remus, so we shall see if he continues to do their bidding.
Interests / Hobbies: Potions, scotch, Dark Lords, Death Eaters, espionage.
Strengths and weaknesses: Strengths Legilimens/Occlumens, one of the finest potion masters in Europe, able to dissemble at need, skilled at hiding his thoughts (and capable of revealing them if necessary as well), genius range IQ, intense trust in those he chooses to trust.
Weaknesses Near-sociopathic dislike of others, lack of ability to emote, lack of empathy with most people, precariously balanced between light, dark, and the third side, Millicent Bulstrode, Firenze, Sirius, egotism, distrusted by many, some degree of penitance for past actions.
