A/N: Guys, after I've written that chapter, I had such a headache that I had to go to bed. I don't know why, but I did. I couldn't think properly. But here's the first chapter!

(Yes, those two chapters were the prologue.)

"I'm going to tell you something your parents were hiding from you. Are you ready?"

"Umm…" – Dipper said – "I guess."

"Alright." – Garnet said – "I, and some others are from an alien race that once invaded the planet thousands of years ago. Some of us thought this was unfair to the life that already existed here, so we turned against our own kind to stop what they've started here. Most of our rebellion died in the war, but our leader, Rose Quartz could protect the closest of her allies. One of them was your mother, Diamond."

"Wait. My mom is a… what's it called… Gem?"

"No. Your current mom isn't. You aren't a full gem. Your father, the current, fell in love with Diamond, and Diamond really wanted a child. But it had a downside. She had to give up her physical form."

A burst of sadness hit Dipper's heart like a million supernovas.

"Your father tried to convince her not to, but to no avail. She wanted to do it, no matter what. And her gem, the diamond on her left arm became yours."

"No." – Dipper fell on his knees – "You must be confusing me with someone else. There's no way."

Mabel put her hands on Dipper's shoulder.

"Can we talk eye-to-eye for a second?" – Mabel asked the strangers.

"Sure." – Garnet and the kid said.

…

"Look, Dipper." – Mabel explained – "They seem to be telling the truth. It all makes sense. Why your… gem is there, why Dad was saying that you're 'different,' it all fits in."

"NO!" – Dipper shouted – "IT CAN'T! I DON'T WANT IT TO!"

"Dipper," – Mabel smiled with sympathy – "You can't change how things are. Accept this."

Dipper sighed and tears fell down on his soft 12-year-old face.

"Why me?" – he asked – "Why was it me?"

"Everything that happened has a reason."

They both smiled at each other and called the strangers to return.

"I have a question – next to the hundred I already have – who is that kid?" – Dipper pointed at the kid.

"I'm Steven!" – he optimistically said – "I'm part-gem, like you! (Except that I'm a year younger than you…)"

"All of this is too hard to process… First that book, now this?!" – Dipper said – "I think I'm going to throw up…"

After getting it out of his system, Dipper questioned –

"What now?"

"You two." – Garnet pointed at the siblings – "Go home, but memorize the location of this place. Tomorrow in the morning, at 7 AM, we meet right here."

"7 AM?!"- Dipper asked. He was a heavy sleeper.

"Yes." – Garnet tonelessly responded – "Steven will be here too."

"Really?" – stars formed in Steven's eyes

"Of course." – Garnet said – "You're the only other being who's like him."

"OK!" – Steven smiled and ran to that crystal pad thingy – "See you tomorrow." – And a beam appeared and the kid got sucked in it.

"What was that?" – Mabel questioned

"A warp pad." – Garnet answered – "It is used by Gems for transportation. It can be used to transport objects, Gems, but with a Gem activating it, humans can be transported too." – she went towards the pad – "Goodbye." – she said as she disappeared.

"Let's go home, then." – Mabel tried setting the mood.

"O-okay." – Dipper stammered. He didn't believe all of this happened. It was irrational! Then he remembered. Many things were irrational in his life before. Why he could take down strong bullies without trying, his intelligence, everything made sense now.

While walking home, he was thinking to call his Dad about this. He decided to do so. He borrowed Stan's phone and called his father.

"Hey, there, Son! How's it going?"

"Please stop doing that, Dad."

"What's the problem, dear?"

"PROBLEM? THERE'S NO PROBLEM! The only problem is that you've been hiding that I'M HALF ALIEN for 12 YEARS!"

Dipper could hear a gasp from his father.

"Who told you this nonsense?"

"I don't know, some magical being who teleported here through A CRYSTAL PAD."

He was very angry. How could their parents do this to him?! He's half -gem and they don't tell him?

He put the phone down due to his anger, and went to his and Mabel's room. He didn't even put on his pajamas, he just went to bed. It was late. And what a day came after sleep.

All of this was too much to process. He's been half-alien for 12 years and no one said a word?

That Steven kid kinda annoyed him too. He seemed… too cheery about this.

[BEACH CITY]

"So there's a part-gem like you?" – Connie asked through the phone – "Is the person a boy or a girl?"

"A boy." – Steven explained and sighed – "He looked really sad when all of that happened. I mean, he just found out that he's part-gem!"

"What?!" – Connie asked – "How could he have not known?"

"His father never told him."

"Well, at least he knows now! I gotta go to sleep, so bye!"

[GRAVITY FALLS, MORNING]

It was morning, and Dipper was awoken by Mabel at around 6:30.

"Dipper!" – she whispered – "We have to go."

"Already?" – the kid asked. He couldn't sleep well.

"Put your clothes on, already." – she angrily whispered.

He hurried and dressed up, and went into the forest.

"Umm, Dipper?" – she asked as they went outside – "Did we memorize the way to that pad?"

Dipper's eyes stood in shocks as he realized they didn't.

"Oh my gosh," – Dipper screamed stressfully – "Don't worry, Mabel, I am 100% sure we'll find the way."

We'll never find the way, Dipper thought.

Mabel raised her elbows as they started walking.

Suddenly, Dipper stopped walking and looking around. After a few seconds of thought, Dipper started running.

"This way!" – he said happily – "Follow me."

After they ran through the forest in, what it seems, random directions, they got to the warp pad, at 6:57.

"We got here just in time!" – Dipper happily exclaimed

"But…" – Mabel said, confused – "How did you know the way?"

"I don't know," – Dipper responded – "This is the path that felt like the correct one."

"Weird…" – Mabel murmured.

Suddenly, at exactly 7:00, a light beam hit the crystal pad and the tall woman and that kid Steven appeared.

"WOW!" – stars formed in the child's eyes – "You were right, Garnet!"

"Right? About what?" – the siblings questioned

"About you arriving here before we do!" – Steven said.

"And how did she know that?" – Dipper asked.

"That's something I'd rather tell you later." – Garnet answered – "Now, come one the Warp Pad. We've got a long day ahead of us."

The siblings stepped on the crystal pad.

"May I?" – Steven asked, looking at Garnet – "Sure."

Suddenly, the kid positioned himself, and the light beam hit the pad again. Dipper felt really weird in the stream. The sensation felt new, yet it felt like he was kind of used to it. After a while, the beam disappeared, and both siblings fell on another pad, inside a house.

"WOW!" – Dipper said, amazed – "Teleportation? That is amazing! How does it work."

"Magic." – Garnet simply answered.

"Wait," – Dipper paused – "Gems are magical creatures?"

"Yes." – Garnet answered again – "And you have magical powers too. You just need to learn to control them."

Dipper was amazed about the whole thing. One moment, you're a simple kid, with a simple life, and the other moment, you find out that your partly an alien race, and that you have magical powers.

It was a lot to take in for him.

"Enough standing around!" – Garnet said – "Let's introduce you to everybody!"

A/N: Sorry for no new chapter for a few days! This may be the only chapter for a few weeks. I'm going on a camp, and then somewhere else, so I won't be able to update regularly. Sorry guys!
