In this AU Isabelle and Alec are regular people and they do not know Jace, Clary, or Simon...yet.

This is rated T! Remember that! It is Rocky Horror based.

I would like, if I may, to take you on a strange journey. Alec Lightwood and his sister, Isabelle Lightwood, two ordinary people, left the city that night to visit a relative of theirs. It is true that the spare tire they were carrying was badly in need of some air. On that night out it was also pouring rain in a terrible storm. A night out...it was a night out they were going to remember for a very, very long time.

Over at the Frankenstein Place

He and Isabelle were supposed to be visiting an old friend of their family's that night. They were sent with directions to the house, but as they wound through a precarious trail -darkened by towering trees - a sign emerged from the gloom. "Dead End"

"I could have sworn we took the right fork in the road, this can't be a dead end," Alec furrowed his eyebrows as he looked at his sister. Isabelle looked equally confused. The woods had a mysterious - almost eerie - atmosphere. The siblings had no desire to loiter in its shadow.

"Alright, I guess we'll just go back." Alec muttered as he shifted the car into reverse.

Not a minute after they started to back up the car the tire blew out.

"Great," Alec sighed, leaning his head back against the seat in defeat. He and Isabelle got out of the car to examine the tire. "Well there's no fixing that… shall we walk down the path to see if there's anything we can use to get help?" he asked Izzy.

Nodding, Isabelle moved ahead, the leaves crunching under her boots.

Stranger than the woods was what they came across next. The siblings stopped dead at the gate of an old gothic castle. The castle gate read, "Enter at your own risk."

"Should we go in?" Isabelle asked, hesitantly.

Alec hesitated a moment, studying the ghoulish castle in front of him. "Yes," he decided, "we might as well see if they know how to get back to the city."

"Plus, it's dry," Isabelle added, pushing her wet hair away from her face.

Alec and Isabelle entered the gate made their way through the long yard. They reached the castle and knocked on the door, shivering and soaking wet.

The door slowly creaked open, revealing a tall man with blond hair. His eyebrows rose questioningly at the sight before him. "Hello."

"Hi," Isabelle replied, always the more confident one, "our car broke down up the road and we were wondering if you had a phone we could use or if you could, maybe, point us back to the city?"

The man gazing down at them replied, "You're wet."

Alec blinked, "Yes… it's raining."

The man was silent for a moment, "I think it would be best if you all would just...come inside."

Alec and Isabelle exchanged glances but did as the man said. "You're too kind," Isabelle tittered nervously.

They were led in to a front animal heads decorated the walls. An old grandfather clock, ticking dully, was pressed next by another door. The room was cluttered, mismatched knick-knacks and oddments littered every surface. The untidy nature of the room detracted from the obvious ornate style of the house, making it seem unwelcoming. Everything was also covered in a thick layer of dust.

Isabelle looked up at Alec, "Alec? What is this place?"

"It's probably just some hunting lodge for rich weirdoes." Alec responded, attempting to calm Isabelle's nerves. Internally, however he was just as unsure of the place.

"This way," The man said pushing past them making Alec – who had been distracted – jump.

Hearing the music coming from the room ahead of them Alec asked, "Are you having a party?"

The man stopped and turned, smiling deviously, "You've arrived on a rather special night – it's one of the master's affairs"

"Oh," Alec blushed, "lucky him."

"You're lucky, he's lucky, I'm lucky, we're all lucky!" A woman who had been on the stairs laughed maniacally.

Alec jumped again having not noticed her there. She had curly red hair and was wearing a black v-neck dress that went down to her knee, but was slitted up her thigh. The sleeves has white ends and she had a white collar to the dress; a typical maid's costume.

The blond haired man and the red haired woman lead them to the room where the music was coming from. When they opened the doors there were at least a dozen people in there dressed very strangely. They wore black tuxedo pants with white socks and black flats. Their tops varied in color, distinguishing them from each other, but the overall effect was that of a – very tight – tuxedo. They all wore different, crazy glasses, or shades, and some had typical party hats.

The siblings watched in bewilderment as the whole party seemed to dance in unison to a song.

It's just a jump to your left, and then a step to your right. Put you hands on your hips, and bring your knees in tight. But it's the pelvic thrust, that really drives you insane. Let's do the time warp again.

Alec and Isabelle stood there dumbfounded. As the song finished, the party-goers collapsed, exhausted on the floor.

Isabelle nudged Alec on the arm, "Alec, say something."

Clapping nervously, Alec cleared his throat. "Well we better get going," he announced. "We have to find our way back and we really wouldn't want to intrude on your celebration."

They began slowly backing away, aiming towards the door when they heard the thunk of the elevator begin its slow descent.

Review? Shall I continue?
