I was motivated to do this after reading TD's Alternate Universe and Ship Set the Sail by Terror of dimensions and Warrior of Twilight respectively. The idea was gave to me by my dear friend Terror of dimensions. Hope you'll enjoy this.

Prologue

"Spike, hurry up!"

Twilight shouted to Spike who was bringing some apparatus Twilight needed for her experiment. The experiment she wanted to try for a really long time. It was spell to take a little look into the future.

"Twilight, you think that's a good idea?" Asked Spike as he brought a few scrolls, a pair of flasks and test tubes and such, "I don't doubt your magic but…"

"Don't worry Spike," Twilight said "What can possibly go wrong?"

Spike gave a eye-roll at this. Surely he wasn't reassured by what Twilight had said but he was himself a little excited as well. Then again, who wouldn't be excited to see possible outcomes of certain event in the future?

"Everything?" Spike said nervously before Twilight gave him a glare "I mean everything will be fine." Spike said sheepishly because he knew that upsetting her can brought forth some unknown consequences; such as she done when she had nothing to write to Celestia about.

"So… how that's gonna work?" Spike asked sitting beside her while she was reading a certain scroll.

"I am glad you ask Spike." Twilight said "You see we need to…"

Then she started to explain to Spike that how that spell was going to work. That explanation went above Spike's head, well mostly. Though he did understand a few parts, the easy ones of course.

"…and we can predict the possible future outcomes."

"Oookay…" Spike said nervously again "So what we do now?"

Twilight's smile vanished as frown appeared at its place, then she giggled slyly and said "Let me show you."

Then she got and levitated the some equipment and began to set them up for the required spell. She knew that nothing would get wrong if she followed the instructions to the spell.

"Watch out Spike!" Twilight shouted as she shielded herself and Spike in a force field. It was all what Spike had feared. She messed up that spell, really messed up.

She was able to go more than half through the spell without any problem, she was almost there. A color changing magical sphere was floating in front of her. Now she only needed a little more focus to finish the spell when suddenly:-

"Twilight,"

She lost all the focus as she heard the annoyed voice of the baby dragon. The sphere began glow brightly and make violent sounds, like it was threatening to explode. Twilight was quick to take action and enveloping herself and Spike in a force field.

"Why I've been teaching you about the importance of focus Spike?" Twilight said

"Ah… sorry," was all what Spike managed to say.

The energy from the sphere radiated slowly as a sound akin to but very low than thunder could be heard. It suddenly moved away from them and tackled with some near by objects before colliding and absorbing itself into a mirror. The thundering sounds were stopped now. Twilight and baby dragon opened their eyes. Twilight looked around and after being confirmed that they were safe now removed the force field.

"What happened Twilight?" Spike asked in shaky voice

"We are alright Spike." Twilight said with calm "Don't worry now."

As Twilight looked around, most of her stuff was still in one piece especially her books. Then her eyes stopped at a certain sight. She saw that a small purple chest which was in her book shelf was damaged and unfortunately the stuff inside the chest was also damaged. She could see the shattered pieces of… a few toys, a photo, and a fake tiara.

She grunts with frustration. "There was a lot of useless stuff around and it has to be this chest to be broken!"

"What was that Twilight?" Spike asked

"It was some stuff I brought here from Canterlot." Twilight said with a sigh "At least, we're alright."

Then all of sudden they heard another sound that came from… the mirror. Twilight and Spike both went closer to the mirror carefully. They saw that the surface of the mirror was swirling around and was morphing slowly into something more vivid, scenery of some kind that looked like the interior of Canterlot castle. Both gasped at this.

"What's this Twilight?" Spike asked with a hint of fear in his voice

"It looks like… that somehow spell is working." Twilight replied

"How?" Spike asked

"I don't know Spike." Twilight replied as Princess Celestia along with a bipedal creature sitting on her back appeared in the scenery. She knew the creature as her close friend and son of Princess Celestia 'Joy Star'. "But I'd like to see where it goes."

Spike nodded and stood beside her eagerly watching into the mirror.

And so it begins.
