You arrived at Hogwarts in your 5th year after being expelled from the previous magical school you went in, due to your rebellious attitude. Snape reluctantly greeted you and accompanied you to your new common room: the Slytherin one.

The Slytherin common room was a long, low underground room with rough stone walls and ceiling, from which round, greenish lamps were hanging on chain. You had homeworks to do but you couldn't help but glance at all the other possibilities: meeting other students, looking through the window to see the cold and beautiful lake full of creatures, and reading the mysterious writing on the wall made by Salazar himself.

What will you do?
