This is my first time doing a request, so I hope it turns out ok. Hope you guys like it!

"C'mon, Marco!" Star grabbed Marco by his hood and pulled him out of his chair, dragging him towards the swirling portal.

"Star, wait!" said Marco as he rose to his feet, forcing the girl to stop, though she didn't release her grip on Marco's hood. "What's so important that we need to go right now?"

"You need to see this thing I found! It's amazing!" Star's eyes sparkled with excitement. "C'mon, I wanna show you." She began to pull on Marco's hood once again.

"Star."

"Whaaaaaaaaaaaaaat!? Marco, we can't keep stalling! What if someone moves the thing!? Why are you so against this?"

Marco sighed, set his hand on his best friend's shoulder, and gestured to the classroom filled with a couple dozen giggling students and one very annoyed teacher. "Because it's the middle of the school day, Star. And we were already late today since you wanted to go dimension hopping before school. So just wait a little longer and we can go after school, okay?"

Star sat down in a huff and pouted. "Fine, I'll wait. But if we don't get to see the thing, it's all your fault."

Marco chuckled. "Alright, Star. But it's only a few hours. I'm sure the 'thing' will be fine."

The final school bell rang as the students of Echo Creek Academy ran out of their classrooms. As Marco was packing his things, he noticed Star running up to him. "Okay, Marco. Can we go now?" pleaded Star.

"Alright, alright. Let's just go home to drop off our stuff first, then we—"

"Nope, we're going right now," interrupted Star as she once again grabbed Marco by the hood. With her free hand, she pulled out her dimensional scissors, cut open a portal, and threw Marco inside.

Before he knew what had happened, Marco found himself lying face down in the grass. He looked up to see Star smiling at something behind him. With a sigh, he rose to his feet and brushed the dirt off his jeans. He looked around. They were standing at the top of a hill overlooking a vast forest. The trees reached all the way to the horizon, stretching out like an ocean in every direction. In fact, the hill seemed to be the only landmark in sight.

"Well, then I guess were going now," deadpanned Marco. "So what exactly was so exciting that we had to go immediately?"

"THIS!" shouted Star as she gestured with both arms to an object behind Marco.

Marco looked to where Star was pointing and his eyes widened in surprise. In front of the teenagers was an ornate cannon. It was made entirely out of gold, bedazzled with gemstones of all colors and sizes. The only part of it that wasn't dazzling in the light was the fuse, a small strand of rope dangling on the edge.

"Woah…Star, how did you find this thing?" asked Marco as he turned toward Star. Star, however, was nowhere to be seen. The only sign of her was her purse, which had been set down near the base of the cannon. "Star? Hey, Star? Where'd you go?"

"I'm in here!" shouted Star, as her head popped out of the cannon. "Now, let's light this puppy up! I wanna see how far I can blast myself in this thing!" She raised her wand, preparing to light the fuse.

"Star!" Marco dropped his backpack and ran towards the cannon. He snatched the wand out of Star's hand before she had a chance to cast her spell. "Get out of there! Nobody's launching anybody out of a cannon. That's just reckless!"

Star looked disheartened. "Yeah, I guess you're right…"

Marco nodded and turned to grab his things. "Good. Now, c'mon we have—"

"But it could also be fun!"

Marco sighed and turned back around to see Star looking at him with sad puppy-dog eyes. "Star, you can't launch yourself out of a cannon. You could get hurt and end up lost in that forest. Besides, we don't know why this thing is here, so I'd rather not touch it." Marco tapped the wand against the golden cannon, and, to his surprise and Star's delight, a beam of light shot out of the wand, lighting the fuse. "Oops…"

"Thanks, Marco!" sang Star.

BOOM

"WEEEEEEEEEEEEEEEEEE! YEAH!" cried Star as she flew through the air.

"STAR!" Marco looked on in shock as he watched his best friend fly into the forest that lay ahead of them. As Star grew smaller in the distance, Marco had no choice but to move. He began to run in the direction Star had flown, chasing the trail of smoke behind Star.

And that's the first chapter. Unfortunately, I have finals coming up, so I need to get ready for that, so this one will probably will take me some time to finish. But I'll do my best to make sure it doesn't take too long.
