Horace Slughorn smiled indulgently at his favourite student as he strode over to the 6th Year Slytherin students. Disheveled and grimy faced, it was apparent that the entire class was unsuccessful in their attempts to brew the Draught of Living Death.

"Now, Severus' said Slughorn cheerfully 'Let's see how you did". Placing a leaf into his cauldron, Slughorn continued; "There should be no surprises here; I daresay that you haven't gotten a potion wrong all year!" As he said this, the entire class stopped their brewing to watch Snape's cauldron explode, and drench him with black goo. Everyone in the class, including Snape's friends, all burst out into laughter, as Snape turned a startling shade of red which was visible even through the black goo.

Slughorn struggled to say anything; "Erm... well... class dismissed!" Slughorn vanished the black goo off Snape, and the boy fled from the potions room, his hair still incredibly greasy from the potion brewing. As he ran out, the rest of the class guffawed at his embarrassment. On the other side of the room, three boys were packing up their books and cauldrons.

"Did you see his face? Brilliant!" Sirius Black chuckled

"He has no friends 'cause all he does is snivel around the place" laughed James Potter, followed by a crude impression of a boy with a hooked nose snorting and sniffing. The two boys continued to laugh and mock the boy as they left the potions room and headed down to dinner, along with their other friend, Remus Lupin. Remus was looking forward to a nice end to his day, but unfortunately James and Sirius had already begun plotting their next prank on Snape, which Remus laughed half-heartedly along to.

Turning into the great hall, the 3 boys spotted Peter Pettigrew waving eagerly from the Gryffindor table, having saved seats for them.

"Worships the ground you walk on, mate" muttered Remus, looking towards James. James only smirked and sat down beside Peter. Sirius and James began to enthusiastically relay the events that unfolded in potions, to which Peter found great amusement.

"Look, the snivelling bastard doesn't want to admit that he was wrong!" sneered James. The group peered across to the Slytherin table, where Snape could be spotted sitting alone, and scribbling furiously into his potions textbook.

Dinner continued on as the conversation moved away from Snape and his greasy hair. But soon, they had something a whole lot more interesting to talk about. All the teachers and the students in the Great Hall swung their heads around apon hearing a loud crash. The entire hall gasped as two teenage girls appeared out of nowhere, and crash landed in the middle of the Great Hall one on top of the other. The girl lying on top clumsily stumbled to her feet, but froze when she saw the entire hall staring at her.

"Oh fu-"

She was interrupted by the second girl standing up from the floor and reacting in the same way. The two girls met each other's gaze, as the first girl tucked a gold necklace into her shirt. Headmaster Dumbledore appeared rather composed throughout this whole situation, although the other professors, not so much. Dumbledore quickly ushered the girls out of the Great Hall, leaving the school in a state of complete and utter shock.

Thanks guys, sorry that this prologue is a bit short, but hopefully it's alright! Let me know what you think! xx
