Aquamarine

We followed the Peridot to a giant platform made of blue crystals.
"These are called Warp Pads. They help us travel over long distances by teleportation."

After we stepped on a blue light engulfed us and we were transported through the light.
"This is the Warp Stream. You are not to leave the stream at any point during warp. It could cause severe harm," the peridot informs us.

The next thing I know, we're on another platform, but in a different location.
"Follow me. It is only a short walk to the facilities where you will be tested, then sent to your Diamond."

She walks a ways to these buildings with tall, broad-shouldered gems stationed outside of them. Bloostone and Obsidian are split off from me and walk into different buildings, leaving me by myself.

The new gems open the black curtains and escort me into the medium-sized space. There is another gem there, of orange color.
"Why am I here?" I finally inquire. The orange gem speaks instead.

"I'm here to push you to your breaking point. To test your abilities, even if it means that you have to retreat into your gem. I'm Jasper Facet-5T1R Cut-52JB, and you're about to have a bad time," she says as she cracks her knuckles.

Bloodstone

I cry out in pain as I'm hit with the purple gem's axe. 'Why are they doing this to me? I only just came into existence and they're trying to kill me!'

I try to summon my weapon, if I even can, but I fail yet again as I'm hit with another blow. This time out of many it struck my shoulder. The tall gem has a smug, satisfied look on her face. I watch it go from smug, to disappointed as I struggle to maintain my form and stumble to my feet.

She charges, ready to deal the final blow. I close my eyes and hold up my arms to protect my face from the blow, but it doesn't come.

I slowly open my eyes to see the, what was it called? Amethyst gem, arm poised as if frozen mid swing. I hear a small gasp of awe behind me. I turn around to see a peridot gasping in awe of what she had just witnessed.

That was the last sight I saw before everything went black.

Obsidian

I hear cries of my two new friends around me. 'What are they doing to them? Why are they yelling? What are they gonna do to me?!'
A peridot walks in. "I'm here to test your abilities, and more importantly, your intellect," she says as she sits down across the table.

"You're not going to fight? Isn't that what they're doing to my friends, Aquamarine and Bloodstone?"
I slap my hand over my mouth.
I didn't want to know, but it slipped out.

The green gem opens claps for another gem, a white one with her gem on her forehead and peach hair.
"What do you need, mam?" inquires the white gem.

"Go get my system. I'm going to need it," she says before turning to me.
"You're not like them. They're natural warriors, unlike you, who is a natural technician. I don't need to test your fighting proficiency."

I watch the white gem leave before I register what was just said to me.
"Wait, so I'll most likely never see them again?"

"Correct," replies the green gem.
The white gem walks back in with a heavy looking case, I start to get up and help her, but I'm stopped by the peridot.

"She's a pearl. It's her job to do things like this. She's an exceptionally fancy one, too. It's a shame White Diamond is sending her off to work for Pink Diamond's top warrior, Rose Quartz."
I sit back down as the pearl opens the case and pulls out two machines. She sets one in front of each of us, bows, and walks away.

"Now, shall we begin?"

A/N

Wow. That was some chapter! I bet you guys can guess who the pearl is, but the other cannon gem isn't so obvious.

Hint: It's in their ID! (Facet- _ Cut- _) Review or PM me if you know who our second cannon gem is! You get a shout out in the next chapter if you guess correctly!

Let me know if you see any mistakes!
