Emerald
I woke up and found that Amethyst wasn't there. I worry that the smaller gem had lured me into a trap, to crush me for being on her beach. I looked around and noticed a door through all the piles of stuff and decided to escape.
I snuck around junk, looking around for anyone watching me. When I got to the door I took a deep breath, not knowing what would lay on the other side.
I walked out to find a large warp pad and a small little creature sitting on a chair. It appeared to be eating something. The creature looked at me and its eyes got real big.
"-gasp- Are you a new gem? Where are you from? Why are you here? How'd you get here?" It rambled on.
"I, um, uh..... M-my name is Emerald," I said looking at my feet, "what are you?"
"Oh! Silly me, I forgot to introduce myself. My name's Steven. Don't be afraid, I won't hurt you."
I looked at Steven's head and noticed a portrait of what appeared to be Pink Diamond!!
"Steven, um who is that?," I said pointing to the portrait.
"Oh, that's my mom, Rose Quartz. When I was born, she gave me her gem because we both can't be alive at the same time. See," Steven said as Steven pulled up part of its outfit to reveal Pink Diamonds gem, " I'm also half human on my dads side."
But why did she go by Rose Quartz? Was it so she wasn't associated with Honeworld anymore? This Steven gem thing is the closest I'll ever get to her. I hope it's nice.
I was just about to ask Steven about Pink Diamond when the gem warp activated and then speared three gems, one of them Amethyst. The two I didn't know took one look at me and took out their weapons.
"EEP," I screamed as I ran towards Steven and fell near his chair.
"Woah hey guys c-"
"STEVEN! I will not calm down because there's a gem in your room and we don't know anything about her!" The white one yelled, she kinda looked like a Pearl.
"Nah, she's cool. You can put your weapons away. Her names Emerald," Amethyst said as she stuffed something in her mouth after her weapon poofed.
"Amethyst, do you know Emerald?," the tall one with glasses asked.
"Yeah, I brought her in last night. She was all soaking wet and was in the beach by the warp pad. She didn't seem harmless Garnet."
"Pearl, I agree with Amethyst. Please put your weapon away, your scaring Emerald," Steven pleaded.
I looked from gem to gem to half gem. Steven seemed nice and so does Amethyst. I'm not sure about Garnet and Pearl seems really hostile.
"Hold on. What is this about a warp pad?" Garnet asked.
"I dunno. I'd never seen it before. I think Emerald warped here on it," Amethyst said.
"How about we ask this, Emerald why it's there," the Pearl spitefully said.
"Um, well. I wanted to leave Homeworld really badly because it's just very violent and I don't like it but I missed the ship to leave. My sister sonehow managed to create a warp large enough to get me here. I don't know how she did it though," I quietly mumbled.
"Sister?" All of the other gems and Steven asked.

Ha ha sorry, cliffhanger. Although it's not THAT bad. I'm terrible at writing Steven, sorry!
