Rise of Project Obsidian

Chapter 1: Welcome Back Obsidian

Floating in a white void we find a female humanoid figure with no identifying features. She was just floating as there was nothing else to do; there was no one to talk to, nothing to interact with, and even if she attempted to go anywhere there was nothing to go to.

"How long has it been since I was shattered, how long have I been floating in this void?" the figure thought to herself.

Think to herself, that was all she could do in this void and if she was being honest with herself it was driving her crazy! She had way too much time to just think, to think about her past, the mistakes she made, and the things she could have done differently. Though what was driving her crazy the most were her thoughts on the gems that were closest to her.

"I wonder if they're alright, if they're safe, if they're happy,...if they miss me like I miss them." the figure thought to herself.

It was then that something strange started to happen, the void started to shake and black cracks started to appear everywhere. Since the figure had never seen this happen before she quickly moved toward one of the cracks. As she looked at the cracks she found that she could see through them and what she saw shocked her. She saw a gem that she knew very well and apparently they were fighting some kind of monster that had her pinned behind a large rock.

"I have to help her, but I can't do that while I'm in this void and I don't know how to get out." the figure said to herself as she frantically looked around but the only thing she saw other than white void was the black cracks. "Well I don't have any other options so hopefully this works." said the figure as she quickly moved and tried to dive through one of the cracks and caused a bright light to shine.

OUTSIDE THE VOID

Garnet couldn't believe how much trouble she and the other Crystal Gems were having with the Centipeetle Mother as it was currently trying to melt them with its acid. She could hear Steven on the other side of the rock trying to help but she knew he could, at best, only distract the Centipeetle Mother since he hasn't gotten the hang of summoning his weapon.

Soon though she and the others heard the Centipeetle scream in pain as apparently Steven had electrocuted it by throwing his Cookie Cat mini refrigerator at it. Just as she and the others were about to move and continue the fight Garnet felt something move within the top of her outfit. Before she could do anything about it a small jagged piece of a black gem tied to a string around Garnet's neck flew out of her top and over the rock currently protecting her.

"No! That's all I have left of her!" said Garnet in a rare show of emotion as she reach of the small piece of gem but it slipped between her fingers. She ran around the rock in order to go get it while being followed by Pearl and Amethyst but they were then blinded by a bright light.

Once the light dimmed a bit Steven ran over the gems. "Guys what's going on!?" asked Steven.

"We don't know steven." said Garnet in her ever calm and even voice.

They all looked up at where the light was coming from, even the Centipeetle, and saw an oval shaped black gem floating in the air. In had many cracks in it and a piece from the middle was missing. Garnet then noticed the piece she had hidden around her neck lost its string before it joined with the rest of the gem. After that all the cracks in the gem started to seal up before the gem became as good as new.

Once the gem was done fixing itself a white light came from it and shaped itself into a female humanoid form before the figure fell to the ground causing a cloud of sand. When the cloud cleared the figure stood up with its back to the Centipeetle, showing the Crystal Gems what she looked like. She stood a few inches shorter than Garnet with a lean frame, wide hips, D-cup breasts, ankle length wild white hair, healthy pale skin, and soft black eyes. Her outfit consisted of a skin tight black bodysuit with a star shaped cut out on her chest that shows her cleavage and her gemstone and a white star pattern going up the side of each of her legs, also on her arms are bicep length fingerless black gloves that had the same star pattern as her legs.

The woman reached for the gemstone embedded into her chest as it glowed and summon two black and white scythes, the staff being black and the blades being white. This caused Pearl and Amethyst to ready their weapons, Steven to be awed at her weapons, and Garnet to continue to stand there in shock at what she is seeing, or better yet who. The woman though quickly turned around and ran at Centipeetle and Centipeetle seeing this as a threat quickly shot a stream of acid at the woman but she easily dodge it before jumping into the air and with only two swings of her scythes she poofed Centipeetle.

When she landed on the ground she dispersed her scythes, picked up the gem left behind by Centipeetle, put it in a transparent black bubble, and turned back to the Crystal Gems before walking over to them and stopping 5 feet from them. Pearl and Amethyst lowered their weapons a bit since the woman had taken out Centipeetle but were still slightly on guard, well Pearl was while Amethyst was completely relaxed since the big bad monster was now gone.

"Wow, that was so cool! Who are you?" asked Steven as he ran up to the woman and unknowingly making pearl cringe. From what the woman could tell Steven was a short human boy with peach colored skin, curly brown hair in an afro, and black eyes. For clothes he wore pink sandals, blue jeans, and pinkish red shirt with a yellow star on the front.

"I'm Obsidian." said the now named Obsidian. That name caused two different reactions out of two of the crystal gems. Pearl raised and tightened her grip on her spear while Garnet's jaw dropped open.

"Steven get away from her!" yelled Pearl as she got ready to fight. Pearl was a rather tall gem for a nonfusion as she came to Garnet's chin with ivory skin, sky blue eyes, a pointed nose, peach colored hair that was in a pixie cut in the front and came to a point in the back, a slender, thin build, thin lips, B-cup breasts, and a pear gem in the middle of her forehead. For clothes she wore a light blue top that had a transparent chest that transferred into a transparent silk ballet skirt around her waist, short salmon pink leggings, light green socks, and matching slip on ballet flats.

Just before Pearl could charge forward in order to move Steven and attack Obsidian, Garnet started walking forward like she was possessed by something. She stopped when she was only a few inches from Obsidian and place her hand on Obsidian's right cheek.

"Is...is it really you...Obsidian?" asked Garnet with more emotions in her voice than the others had heard before. Garnet was the tallest gem with medium maroon colored skin, plump lips, a black cube shaped afro, D-cup breasts, and her gems were embedded in her palms. She wore a black and crimson bodysuit with cubic shoulder pads and a yellow star with a magenta outline on her chest, elbow length black gloves that cover her middle fingers, and triangular futuristic shades.

"Yeah it's me….hey Garnet." said Obsidian with a small smile. Obsidian was suddenly brought into a tight hug by Garnet that caught her by surprise but she didn't hesitate to return the hug.

"Hey Garnet you know this gem?" asked Amethyst since Pearl was in too much shock to ask. Amethyst was the second shortest gem since she was slightly taller than Steven with bright lilac skin, thick, messy pale lavender hair that went down to her ankles with a bang covering her left eye, indigo eyes, plump lips, and her gemstone was embedded in her chest with the bottom half being covered by her shirt. For clothes she wears a mauve, oversized, off the shoulder tank top with a black bra underneath, black leggings with star-shaped cutouts on the knees and a tear above the left knee, and pointed white boots.

"Of course Garnet knows her, that's Obsidian, the only gem to work directly under all four diamonds. She's also called the Obsidian Reaper thanks to the scythes she used to cut down our numbers during the war." said Pearl with a sneer. Obsidian looked down in shame as her past actions were brought up but Garnet still hugged her.

"While that is true Pearl, that was early on in the war. I wouldn't be hugging her if that was still true, she changed during the war and came to join the rebellion though that was only known to a select few." said Garnet as she finally let go of Obsidian.

"Did Rose know about this?" asked Pearl with disbelief clear in her voice.

"Of course she did." Garnet said simply.

"Speaking of that big ball of pink sunshine, where is Rose, it feels like forever since I've seen her." said Obsidian. At that question everyone seemed to get quiet, especially Pearl. "What, what's wrong?" asked Obsidian.

"Let's go inside there is a lot to catch you up on." said Garnet as she took Obsidian's hand and led her inside with the others following.

IN THE HOUSE

Sitting on the couch Obsidian couldn't believe what she had just learned. The war was over and they had won, but the cost was great since only Rose, Garnet, and Pearl had survived with Amethyst emerging close to the end of the war. Then there was the fact that Rose had apparently fallen in love with a human and given up her physical form in order to give birth to Steven. Now they've been helping Steven's dad Greg take care of Steven while also protecting Beach City from corrupted gem monsters. It was a lot to take in after only just coming back from being shattered.

It was late now and Steven had gone to bed while the Crystal Gems had just finished catching up Obsidian. "I….I need some air." said Obsidian as she walked out of the house and onto the beach.

"Shouldn't one of us go watch her?" asked Pearl.

"No she's fine, but I'll go check on her in a few minutes." said Garnet.

"I guess that works." grumbled Pearl.

"Aww come on Pearl, if Garnet says she's alright then she's alright." said Amethyst as she got up and went to her room.

"Garnet you said you saw Obsidian shattered during the war, so how is she back?" asked Pearl.

"I don't know, we kind of forgot to ask her." said Garnet.

OUTSIDE WITH OBSIDIAN

Obsidian sat on the beach watching the waves crash onto the shore as everything she learned set in. So many good gems were gone now or are corrupted, Rose was gone, and she had no idea if her last two friends were okay. It was then that she heard someone sit next to her on the beach and turned to see that it was Garnet.

"How are you feeling?" asked Garnet.

"Better….it still a lot though but I'll do better in time." said Obsidian as they fell into a comfortable silence.

After a few minutes Obsidian felt Garnet grab her right hand. Obsidian looked to her right and saw that Garnet had taken her shades off and was showing her three eyes. Garnet's right eye was medium ruby-red, her left eye was medium sapphire-blue, and her middle eye was medium reddish-violet. Obsidian was then pulled into another surprise hug like earlier that day but this time Obsidian could feel her shoulder becoming wet. She knew why Garnet was crying and just held her tighter as tears began to leak from her own eyes.

"I-I thought….that….I'd lost you." said Garnet.

"It's okay, I'm here now and I won't leave you again." said Obsidian.

"But how are you here?! I saw you get shattered, I watched as your gem fell to pieces!" said a frantic Garnet.

"Calm down Ruby, you don't have to relive that day." said Obsidian.

"You're right we should focus on now and the ever changing future." said a now calm Garnet.

"Thank you Sapphire, like you said let's focus on now and the future." said Obsidian.

"How do you always know which one of us is talking." asked Garnet.

"I've known you since before your two halves even met, now that you're always together I just know which one is talking over the other. Ruby is always so wild and passionate while Sapphire is calm and graceful. Together they make a truly beautiful gem." said Obsidian before she pulled back from the hug a bit and then planted a deep kiss on Garnet's lips. Garnet didn't hesitate to return the kiss as they held each other tightly.

It had been so long since they've kissed like this and they were savoring every second of it. Obsidian was running her hands up and down Garnet's back while Garnet was running her hands through Obsidians hair all the while their breasts were pressed together. After a full five minutes they finally broke the kiss.

"I love you Garnet." said Obsidian.

"I love you too Obsidian, I never stopped." said Garnet as they fell into a comfortable silence and just held each other.

"I'll tell all of you how I'm back in the morning, after I decide what I'm going to do." said Obsidian.

"You can stay with us and be a Crystal Gem." said Garnet not wanting Obsidian to leave.

"That sounds nice, but whatever I decide to do just know that I'm not leaving you again." said Obsidian. After a few more minutes Garnet went back into the house while Obsidian decided to stay outside for a bit longer.

THE NEXT MORNING

Garnet and Pearl watched as Steven and Amethyst ate breakfast. Sure Amethyst didn't need to eat but she liked to anyway.

"Hey guys, where's Obsidian?" asked Steven.

"Yeah, where is Obsidian, she never came back into the house last night." said Pearl with suspicion clear in her voice.

"She's out on the beach, she had a lot of things to think about." said Garnet.

After Steven and Amethyst finished eating they went outside to look for Obsidian. They found Obsidian in the same spot she was in last night but instead of just watching the waves she was standing in the surf practicing with her scythes. Obsidian's movements were graceful and flowed together in a beautiful symphony of movement made even more impressive by the fact that her eyes were closed and she wasn't losing her footing. Even the water itself seemed to be following Obsidian's movements almost like a deadly dance between Obsidian and the water, a beautiful dance that awed everyone but pearl.

Garnet smirked a little as she remembered the times she would spar with Obsidian whenever she wasn't doing a mission for Rose. It was through those spars that Garnet found out why Obsidian was Home World's strongest soldier because while her attacks were beautiful, they were also powerful and flowed together so well that you barely had time to counterattack. Not to mention that Obsidian's style of fighting left very few holes for you to exploit.

Amethyst was amazed and blushing a bit because she had never seen anyone fight like this before. Sure she had seen Pearl doing something similar whenever she went into Pearl's room but she somehow made it seem boring while this seem exciting. She was blushing a bit because the water had apparently splashed Obsidian a bit and had matted her hair down to point that it clung to her skin and Amethyst watched closely as water droplets trailed down Obsidians body as some became lost in Obsidians cleavage.

Pearl glared as she remembered these same moves being used to cut down her comrades. They might have been beautiful but they were deadly and ruthless. She remembered how no matter how many gems were sent to fight Obsidian all of them were either poofed or shattered before Obsidian moved on to the next group.

Steven's eyes were stars as he watched Obsidian. He only ever saw the gems use their weapons to fight gem monsters, he had never seen them actually practice with their weapons. The closest he's come to seeing something like this was when Pearl tried to explain to him how she summoned her weapon.

Obsidian finished her training with two strong swings of her scythes that actually caused the water to split in two different directions and stay that way for about 5 seconds before returning to normal. Once she was finished Obsidian opened her eyes and saw the others standing there, she had her scythes disappear before giving them a small smile and waved at them.

"Good morning everyone, I hope you are doing well." said Obsidian as she started to ring the water out of her hair.

"That was soooo coool. Can you teach me how to do that?" asked Steven.

Obsidian giggled a little at Steven's excitement. "Sure but only if Garnet is okay with it." said Obsidian.

"Not until you're older." said Garnet when Steven turned to her with a pleading look on his face.

"Awww, okay." whined Steven before he felt someone ruffle his hair.

"It's okay, you'll be older before you know it." said Obsidian.

"So Obsidian, how are you standing before us when Garnet saw you shattered?" asked Pearl with her arms crossed over her chest and her eyes narrowed.

"Right that. I did promise Garnet that I would tell you all so let's go inside and sit down." said Obsidian.

INSIDE THE HOUSE

"Alright as far as we all know I am the only Obsidian in gem society. The reason for this is because Project Obsidian was an experimental project thought up by the Diamonds in order to create a gem that could reform itself after being shattered. They pooled their resources together and made me, but because of the amount of effort it took to make me they couldn't risk shattering me to test if I would reform. They sent me on tough missions to see if I would shatter but I always succeeded in my missions, I guess now we know that the project was a success." said Obsidian.

"If it was such a success then why did it take you so long to reform?" asked Pearl.

"Hmmm, the only thing I can think of is that because Garnet kept a piece of my gem with her after I was shattered it wasn't close enough for me to pull it in and reform. I think that since this was the first time you were close enough for a long enough time my gem was finally able to pull in the final piece needed to for me to reform." said Obsidian.

"Wow, so you could be shattered over and over again and just put yourself back together again!" said Amethyst.

"I believe so but I would need all of my pieces to be close by." said Obsidian.

"So what are you going to do now Obsidian?" asked Steven.

"I think I'll take Garnet up on her offer and become a Crystal Gem, or more specifically I'll take up the same position I had with Rose though I'll do it for you Steven." said Obsidian.

"And just what position were you with Rose?" asked Pearl not liking that Garnet had offered Obsidian a spot on the team.

"I was Rose's personal guard and Spymaster." said Obsidian.

"There is no way that is true because I was her personal guard!" said Pearl.

"Yes you were, but you couldn't be with Rose all of the time so when you weren't with Rose Obsidian acted as her guard. In fact it was thanks to a special ability of Obsidian's that I started calling her Rose's Shadow, Rose herself found the nickname cute." said Garnet.

"Why did they call you my mom's shadow?" asked Steven.

"Because I found that I could do this." said Obsidian as she stood up and walked over to Steven. She stopped in front of him and then stepped onto his shadow before she began to sink into it until she disappeared.

"Whoa, she can hide in people's shadows!" said Steven in excitement.

"Not just hide, I can travel through the shadows." said Obsidian as she came up out of Garnet's shadow.

"Wow, that is so cool!" said Steven and Amethyst.

The rest of the day was spent at the house with Obsidian getting to know Steven and Amethyst better. Pearl was distant and stayed in her room mostly. Garnet had left on a solo mission and said that she would be back later. Amethyst introduced Obsidian to eating and sleeping which Obsidian reacted to differently. She didn't mind eating but she probably wouldn't be doing it too often and as far as sleeping went she did like doing that, it was very relaxing. She experienced this by taking a nap with Amethyst on the couch though when they woke up they were cuddled up together with Amethyst's head resting between Obsidian's breasts and Obsidians right hand on Amethyst's ass. Needless to say both of them could barely look at each other without blushing after that. All in all Obsidian found Amethyst and Steven to be fun to hang around with.

THAT NIGHT

"Hey I know it's kind of late to be asking this but where is Obsidian going to be staying?" asked Amethyst to Garnet who had come back from her mission. Pearl was wondering this as well as she didn't feel safe just letting her be anywhere unsupervised. Steven was already in his bed sleeping.

"I can just stay on the couch." said Obsidian.

"Nah, you can stay in my room if you want." said Amethyst with a small blush.

"Obsidian will be staying in my room since I don't sleep." said Garnet in a matter of fact voice.

"Well with that settled I'm off to my room." said Pearl. She was happy with this arrangement since Garnet would keep watch over Obsidian since she doesn't sleep, while Amethyst could probably sleep through an earthquake. Amethyst pouted a bit at this but nodded her head anyway, she found that Obsidian's breasts made for a great pillow.

IN GARNET'S ROOM

"Thanks for letting me stay in your room Garnet." said Obsidian as she sat on Garnet's unused bed.

"It's fine." said Garnet simply as she stood there watching Obsidian. Most would be unnerved with someone just watching you, but Obsidian was used to the way Garnet was.

"Have you ever tried sleeping Garnet?" asked Obsidian.

"No." said Garnet.

"Would you like to try sleeping with me?" asked Obsidian with a blush on her cheeks.

"...Okay." said Garnet before she laid on the bed next to Obsidian. At that point Obsidian snuggled up to Garnet and laid her head on Garnet's breast while wrapping her arms around Garnet's waist. Garnet slowly wrapped her own arms around Obsidian since she wasn't used to doing this, at least while laying down.

"Goodnight Garnet." said Obsidian.

"Goodnight Obsidian." said Garnet.

There you have chapter 1 of Rise of Project Obsidian I hope you enjoyed reading it as much as I enjoyed writing it. Now yes Obsidian will know a lot about Rose but she won't know everything as no one really knew everything about Rose not even Pearl. The reason for Obsidian betraying the Diamonds will be revealed at a later time.
