Name: Sirius Black III
Age: 17
Year [if attending Hogwarts]: 7th
House: Gryffindor
Appearance: Fairly long black hair, pale skin, just over average height, with "casual elegance".
Personality: Fun-loving, easy-going, casual, and a little rebellious.
History: Sirius was the first of the Blacks to be sorted into Gryffindor, just adding to his feeling of separation from the rest of his family, whom he grew to detest. He became close friends with James Potter, as well as Remus Lupin and Peter Pettigrew, with whom he created the Marauders' Map (his nickname being Padfoot - his animagus form is a large black dog).
RP Sample: Grinning to himself, Sirius arranged himself in an armchair - his legs draped across one arm of it - in the empty common room, waiting for someone interesting to turn up. It had been a surprise to come down on Sunday morning and see no one here, but it was a nice day, and he supposed everyone was making good use of their free time. Even James had deserted him - he hadn't even woken him for breakfast, meaning that when Sirius got up just after midday, the plates had been cleared and his stomach felt as empty as the common room looked. If only something exciting would happen today... But, if it didn't, his imagination could suffice.
