The Gryffindor Common Room is located in Gryffindor Tower. To enter the room, you need to give the right password to the guardian painting, the Fat Lady. The Common Room is also the only way of getting to the Gryffindor Dormitories, where the Gryffindor students sleep.
Remember, Curfew is 10:00!
Kissing is allowed, but if you're going to do something more then that get a private room, and NOT in the public common room or you will instantly get detention.
Don't be a Mary Sue please, I mean if you're the son or daughter of someone you have to be accepted by Reyandbb8starwars, nothing stupid like I'm the daughter of Draco and Hermione Because we all know that isn't possible, and wouldn't even happen. (Sorry people who ship that, I just don't really like the ship)
You are not allowed to show another house how to get into the Common Room (Unless you're bringing them in there or if it's for plot), if you are caught doing so you will be taken to the Headmaster's office.
Respect Prefects and Head Girl and Boy, they are trying their hardest to help represent Gyffindor. (By this I mean like don't disrespect them in the presence of another house, it would be very embarrassing.)
OC's are mostly appreciated, unless you get an okay from me to be a Canon
