Stirring from his sleep the Basilisk could hear something going on in the Main Chamber. He didn't want to go out. The Last time he had gone out he had a sword shoved through the roof of his mouth. He had woken a year or so later to go out hunting. And things had only gotten worse.
The Basilisk woke up. His eyes had healed somehow so he could see he was alone in the Chamber. Rising up he felt very embarrassed. He had passed out laughing. The Basilisk used his tongue to examine his mouth. He paused. The wound in the top of his mouth was gone, but so was his fang. He twisted to look down into the water and opened his mouth. He was not mistaken.
'One of those brats stole my fang,' He hissed angrily. Looking to the entrance he noticed that it was still very much blocked. 'And didn't even bother repairing the damage that they caused.' Sighing he flicked one of the statues by the pathway in order to activate the magic. Even though he was a Basilisk he was very particular about his lair so he had asked Salazar to put enchantments in place so that the Chamber would automatically repair and clear itself if things became to bad. After confirming the reconstruction of the Entryway and the orderliness of the underground labyrinth in general he was satisfied.
'Now to find something to eat,' He said to himself coiling in the main chamber. After a few moments thought he dove into the watery passageway to the Black Lake. Maybe a good Mer will make me feel better, He thought to himself. Emerging at the bottom of the Black Lake he swam slowly through the cool water. Now that he was no longer in the Chamber he was calmer, until he saw what appeared to be a young woman being attacked by Grindylow.
To the surprise of the very large and dangerous snake the Grindylows swam towards him to attack him. He hadn't done anything yet! They swarmed over him. This is not my decade…
Shuttering at the memory he curled up tighter. They were very persistent things. They had clawed at his face, so his eyes had hurt and been a little blurry for the next few minutes. But it hadn't stopped there. It was like someone was after his sanity. Who ties up students and children underwater?
Using his tail the Basilisk had tossed her out of the lake. She should land in the far more shallow part, but not hard enough to get hurt. Turning he swam deeper. He didn't remember the students coming in so deep. Then he saw the Mer, but it wasn't just the Mer. There were four people tied down here. All except for one two looked like students from Hogwarts. The two others looked like they were not old enough to go to Hogwarts. But he could be wrong, since the Grindylow had somehow managed to scratch his eyes his vision was a little blurry.
'What the crap are they thinking?!' He exclaimed. Then went to work chasing the Mer angrily. Several Mer later he returned to bring them to the surface only to find what looked to be a half shark trying to eat one of the girls. With a quick flick of his tail the shark thing was flung away towards the shore. Biting the ropes quickly and efficiently, despite his large size, he swam towards the surface. With a nudge they drifted towards the surface. They seemed to wake up when they hit the surface and that's when everything started to go downhill, for him of course.
The Basilisk stopped the memory and shuttered again. He didn't want to remember. He was really regretting meeting Salazar at all at the current moment. After several minutes he sighed and opened the doorway to the Main Chamber. He had a feeling he was going to regret this.
The Weasly Twins sat on top of Salazar Slytherin laughing so hard tears were pouring from their eyes as they watched the trio. Since they had been waiting down here for a while they had decided to booby-trap the Chamber for fun. It was so worth it.
An hour or so earlier...
The trio had looked practically everywhere.
"Where are they!" Ron screamed. He was so angry. They could not change their appearances back. They had tried everything. Now they were searching for the Weasly Twins with powerful glamor's concealing the embarrassing results of the pranks.
"They have to be somewhere," Hermione said logically.
"But where, they must be somewhere?!" Ron said going absolutely ballistic. Harry's eyes widened and he pulled out the of the Marauders Map. With a smirk he saw two dots going towards Myrtle's Bathroom.
"Found you," He said.
