Chapter 1: Miscast

Titan's Tower, Jump City.

It was a nice quiet day in Jump city, especially for the Teen Titans, who were each enjoying the day in their own way; Robin was in the gym training, Cyborg and Beast Boy were playing video games, Starfire and Terra were busy watching them and cheering them on and Raven was in her room reading through one of her books, studying a spell she'd recently found.

"Okay, this seems fairly complicated…" she said in her usually monotone voice. "According to this, this is a spell for opening a 'Universal window', hmm…"

Meanwhile inside the tower

At that exact moment down in the main room, Cyborg had just won his 10th consecutive victory on Mortal Combat: Deception.

"Man this is gettin' old" he complained "That's the tenth win in a row, it's like your not putting any effort in anymore BB" he said to his green skinned friend. Beast Boy turned to him in disgust.

"Dude! You were cheating and you know it!" he snapped in protest, Starfire got up from the couch and walked up to the two, in an attempt to comfort the shape-shifter.

"But friend Beast Boy, I did not see Cyborg doing the 'cheating' as you put it" she calmly pointed out. Beast Boy ignored her, and continued to rant.

"I was so putting effort in! But you kept crowding me and not giving me any room to move." He pouted in annoyance. Terra just shook her head as smiled at him discreetly before putting forward her opinion. "Come on BB relax, I'm sure you'll do better next time." But BB wasn't interested, he just sat their pouting, so Cyborg decided to cheer him up.

"Aw c'mon man, look, if it makes you feel any better, I'll go easier on you next game. What do ya say?"

At that moment, Robin was in the gym, looking mildly worn out from his exercise, he walked out of the gym and walked to the elevator and rode it down to the common room, once there he went over to the kitchen to grab something to drink from the fridge, and then he turned to the squabbling pair.

"Hey guys, what's going on? I could hear you arguing from the gym." He walked over and stood next to Starfire, who was floating about three feet in the air.

"Dude, Cy's been cheating again!" BB complained.

"Err, no I haven't grass stain, it's you, you getting soft in your old age" the robotic titan shot back.

"Friend Cyborg, I am confused" said Starfire "How exactly has Beast Boy aged?" Starfire's naiveté never ceased to amaze Robin, who decided to correct her before she made a fool of herself.

"Ah, no Star, Cyborg is just joking." Robin pointed out.

"Oh" Starfire said simply.

Beast Boy had had enough of this; he decided to make a better use of his time, so he stood up and turned towards the kitchen.

"I'm gonna start launch" he said.

At this Cyborg immediately jumped up and ran after him yelling "Oh no your not! We are NOT having anymore of that tofu crap you call food! I'm doing dinner so that means we're having MEAT!"

"No way rust bucket! We're having tofu!" Beast Boy retaliated.

Robin was getting annoyed at this arguing, it happened EVERY TIME the team had a meal, the meal was always pre-ceded by a tofu verses meat fight, it had become an odd tradition in the tower.

Fortunately for him, Raven entered the room at that moment carrying her book; he took a moment to admire her beautiful face, light grey skin, gorgeous amethyst eyes, and violet hair before he went over to talk to her.

"Hi Rae" he said.

"Hi Robin" she replied, letting smile grace her lips as she looked at her friend, the same person she'd spent the last several months 'paying attention' to, she had recently gained more control over her powers and emotions and decided to chance a relationship with the one-person who knew her better than anyone, and so, a few weeks ago while taking an after-sunset walk in one of the parks near the bay, they had both revealed their feelings for one another.

"Don't you ever change clothes?" she asked him using their mental bond.

"Nope" he replied.

Robin noticed the book in Raven's hands. "Reading anything interesting?" he asked.

Raven nodded. "It's a new inter-dimensional spell I found; I was just reading up on it, it looks really complicated".

"Well, just be careful if you decide to try it, I don't want to loose you to some spell that's gone wrong" he said with a smile. This caused Raven to blush slightly, and her smile widened. "Thanks Boy Blunder"

"No problem dark bird" he replied with a cocky grin, Raven punched him playfully in the arm before stepping past him to sit on the couch, where Star and Terra had once again positioned themselves.

Meanwhile, the two resident chefs continued their never-ending war in the kitchen.

"Dude! I said TOFU!"

"AND I SAID AND CONTINUE TO SAY MEAT!"

This went on for another fifteen minutes or so before Robin finally intervened and settled the argument, and Cyborg ended up cooking, and BB ended up with a potatoe salad, just to make sure he didn't feel left out, Terra shared it with him.

Later, while on the roof, Raven sat with the book, and the ingredients for the spell, once everything was arranged she began chanting.

"Azarath Metrion Zinthos…Carazon…Invisionay…Portalus Infinitay…Vas–"

"Hey Raven!" Raven's concentration was instantly broken by Beast Boy as he interrupted her at the worst possible time.

She looked sharply over her shoulder to give him a death glare before realising something was very wrong. She turned back to the spell and her violet eyes widened in shock and horror, the portal had begun to form, but because the incantation had been interrupted before it was complete, the spell was miscast, and now she was being sucked into the portal without any idea where it led.

"NNNOOOOO!" she screamed as she was pulled into the portal, just as she vanished, the other Titans appear beside Beast Boy, staring in shock.

"RAVEN!" Robin screamed and raced forward and jumped into the portal before anyone could stop him.

As the portal sealed, the others stared in shock and bewilderment before three pairs of eyes turned to give death glares to a certain changeling.

"Err…oops" he said cowering.

As Robin and Raven were pulled through the portal, they found themselves being dragged forward along a tunnel whose walls rippled with white and blue energy, as Robin finally caught up with Raven, he grabbed her right hand in his left and held it tightly.

"DON'T LET GO!" Raven screamed and the howling wind of the tunnel blew all around them. "DON'T WORRY!" Robin yelled back, "I WON'T".

Suddenly, they were thrown violently to the side and left the tunnel they were in, and the howling stopped, but they found themselves in another tunnel, this one looked really weird to Robin, because the walls of the tunnel looked as though they were made of water, but they also looked like they were surrounded by stars or galaxies, because said stars were rotating in a clockwise direction along the tunnel in the direction they were going, so it looked like the tunnel had a spring made of star clusters and constellations wrapped round it's walls.

This tunnel wasn't straight either like the other one; the two birds were being pulled rapidly round sharp bends in the tunnel, as though they were riding the rapids of a river. Suddenly they came to what looked like, at least to Robin, a pool of water standing on it's side, but then he was pulled hard to the right, almost loosing his grip on Raven's hand and he found him self being pulled down an identical tunnel, this time in a gentle curve, to another portal that looked like a pool of water, then this time Raven was pulled to the left and upwards, this time she nearly lost her grip on Robin's left hand, this third stellar tunnel was straight but it wasn't long before they came to another portal, and again turned another corner.

They encountered two more portals, making six they had seen in total before finally finding themselves in a long straight tunnel, but when they had encountered the sixth portal, Raven's hand had slipped out of Robin's grasp and he had lost her.

When he looked down the final tunnel, he saw her ahead of him, heading, at very high speed, to what looked like a seventh portal, only this one was white, and glowing.

"Ok, looks like I'm reaching the end of this damn ride. Beast Boy, the next time I see you I'll KILL YOU!" he thought venomously, then he felt his speed accelerate as he reached the final portal.

Stargate Command; Cheyenne Mountain, Colorado. Alternate reality.

Gate control room.

Sergeant Walter Harriman leaned back in his seat and sighed. There had been no gate activity for two days, though sever SG teams were off world, SG-6 were do back anytime now. So it wasn't much of a surprise when he heard the Stargate activate and the inner ring begin to turn, and the alarm in the Gate Room begin to wail, signalling an incoming wormhole, he instinctively activated the base's internal comm. System and said two words that he knew would get the attention of SG-1, the SGC's flagship team and the SGC's commander, Brigadier General Jack O'Neill. (1)

As the Stargate finished dialling and the wormhole engaged, SG-1 and O'Neill walked into the control room.

"Walter?" Jack asked.

"We got an incoming traveller sir" the gate operator inform smoothly.

"Who is it?" Colonel Samantha Carter or 'Sam' as she liked to be called, asked.

Walter consulted his readouts. "SG-6 is due back from Chulak today, though I think they're early. We haven't received an IDC yet"

Robin saw Raven approach the portal then disappear into it, then found himself getting closer. "Ok, this shouldn't be too difficult" he thought.

In the control room, just before O'Neil was about to give Siler the order to close the Iris, the protective barrier that covered the event horizon, the blue portal that looked like the surface of a pool, something, or rather someone was thrown through the event horizon, and completely missed the gantry ramp leading up to the gate.

The figure in question, Sam noticed it was a young girl wearing a black leotard and blue cloak with a hood covering her face; she hit the metal floor of the Gate room at high speed and with enough force to knock her out cold instantly. Her momentum caused her to roll a few feet after landing, but she was already out.

Robin accelerated towards the portal and suddenly there was a flash of light, and he felt himself flying through the air, then suddenly he felt pain as he hit a metal floor and rolled, he felt excruciating pain in his left arm and chest, he new he'd broken something, when he came to a stop, he raised his head of the floor for a few seconds to search for Raven, he saw her sprawled out about three feet from him, he painfully reached out a hand to grasp one of hers.

"Raven…" he groaned quietly before he too lost consciousness, but before he did, he heard six words over an intercom speaker that confused him.

"Medical team to the Gate Room!" O'Neill shouted.

1: This story is set during season 8 of Stargate SG-1, after O'Neil was promoted from Colonel to Brigadier General
