Author's Note: I do not own The Mortal Instruments or The Infernal Devices, Cassandra Clare does. I do not own cornflakes or unicorns either :) This is my first fan fic so review and tell me what you think. Thanks and happy reading.

Chapter 1: The Portal

"No."

"But, Jace! I've done it before and it worked, come on!" Insisted Clary.

"I said no and that's final" Jace replied curtly, scowling his usual Jace scowl with his arms crossed.

"Oh, come on Jace, it'll be fun." Isabelle cut in from her perch on the big wooden desk in the library, where she sat engrossed in painting her nails a blood-red scarlet, fish-net stocking clad legs crossed. "Clary's first portal worked, she got to Alicante just fine."

"Isabelle if it hadn't been for Luke, Clary would either drown in Lake Lyn or gone completely nuts which, I am wondering if you both are at the moment for wanting to go in the first place."

"Who's what and where are you guys going?" Asked a confused Alec having heard the last part of Jace's tirade, as he stalked into the library where the full-blown war was raging. Dressed in his usual worn-out jeans and sweater that looked like it had been in a fight with a demon its self and lost.

"Clary and Isabelle have decided to try and get us all killed by conjuring up some portal of certain death." Jace burst out in exasperation, moving to sulk over in the corner by himself.

"Okay then." Alec said dropping into an empty plush armchair by the fire.

"Seriously, Alec can you quit the whole emo act for five seconds and help us out!" Isabelle whined while blowing her freshly- painted nails.

"I can't Magnus is going to be here any minute and I don't feel like choosing sides and being killed in my sleep because of it."

"Well, if-" Isabelle started only to be cut off by the glittering warlock himself.

"The magnificent Magnus Bane is here. Hold your applause!"

Magnus in his usual glittering-glory strode into the room clad in white leather pants laced with rainbow ribbons and a splatter-painted shirt, hair spiked with a wild combination of sparkles and neon-color streaks.

Jace rolled his eyes and made a face.

"Looking as usual puked upon by a rainbow and made-over by a unicorn on crack."

"Who crapped in your cornflakes, Shadowhunter?" Magnus asked in a mocking tone of voice.

"You w-"

"Shut up, Jace. Sorry, Magnus Jace is frustrated because Izzy and Clary wanna make a portal" Alec in a apologetic tone said.

"A portal? Why didn't you just say so? I am the High-Warlock of Brooklyn after all! And besides, I've got some old friends I'd like to meet back up with"

"No, Mag-"

"Yes! See, Maggies on our side!" Isabelle shrieked, jumping off the desk and clapping in delight.

"MAGNUS! I swear if you do. I'll you right now. Right here with my bare hands!" Jace warned.

"Is that a threat, little shadowhunter? Come at me, bro. Bring it on!" Magnus bounded around the room, fists raised. "That's very ungrateful, you know."

"I mean it, Magnus-"

Just then blue sparks flew out of Magnus's palms slowing turning into a steady flame. The room was washed in an aqua glow. He thrust his hands to the library's wall and a huge hole suddenly appeared.

"Ohh, cool!" shouted Clary as she raced to the portal and flung herself in.

"Clary, nooo!" Jace shouted as he flung himself into the portal after her.

Isabelle shrugged. "Guess I'm next" and gingerly hoisted herself in and then disappeared. Magnus looked over to Alec, "You coming" then grinning, disappeared into the portal's depths.

"Ogh, apparently so." And with a sigh stepped into the gaping hole, with no clue to where they would all end up.

Ooh! What will happen next? Where will the MI gang end up?

You'll have to wait for the next chapter to find out!
