Hogwarts

You are 16 years old, you have been studying at Hogwarts for five years, in the Ravenclaw faculty. Today is the first day of the new, first semester. The train arrived at the platform. The students began to board the train. You too. You went into one, empty compartment and sat down. You put your things down, your cat was next to you and you looked out the window.

The train left

You were alone in your compartment, but after a while you heard someone's footsteps. The doors to the carriage opened and you saw two boys with their owls. One blond was from Hufflepuff, and the other black-haired from Slytherin. Aziraphale:: Can I sit with you? All the compartments are already occupied. Said the blond from Hufflepuff - Aziraphale. And the black-haired from Slytherin - Crowley just stood leaning against the compartment door. He had the kind of face that if you refused to let them in, he'd still go in and drag Aziraphale along with him.
