Those Slytherins

See 5 girls, two Gryffindors, two Hufflepuffs and one Ravenclaw, battle it out against that bitch Penelope, see fallouts, betrayals and fights. This is something you are gonna wanna see. Set in the past, you will see all of your favourite characters return from the dead - Snape, Dumbledore and many others. Set before the time of Harry and his friends, we may bump into marauders.
(I apologise for bad spelling & grammar, it's my first real fanfiction, no hate please, I'm still experimenting. If you don't find it interesting then don't read it, simple as that. May be some bad language.)
