A/N: So I decided to do a Dark Souls crossover with Steven Universe. I have a rough idea for the story planned out, but the details I'll fill in along the way. Have fun and R&R!

Deep inside a seemingly bare cave, there was a dull humming sound penetrating through miles of rock and dirt. From the outside, this cave may have appeared ordinary, but Peridot had been using it as her makeshift base for the last few months, so the previously vacant structure was now aglow with lime-green lights. Deep down into the cave, the narrow tunnel opened into a large room that could hold two basketball courts side to side. The steady drip of stalactites had been all but replaced with the background noise of whirring machines and of course, Peridot's near-constant audio logging.

"Audio Log 196," The green gem began, coughing once to clear her throat, "We may have found a feasible way to take control of the innate powers of gems themselves. If my intellect could control a more powerful gem, defeating the Crystal Gems should be simple. This really shouldn't be necessary, but Lapis continues to be negligent towards my ideas and will not cooperate." Peridot glanced towards the ocean gem, who had been held prisoner in a laser cell ever since the Machalite incident. The blue gem refused to even respond to Peridot in the months since. Peridot could also turn to Jasper, but she knew that the warrior was still reforming after the accident.

Warrior gems took longer than most gems to reform, and the time needed also depended on the size of the gem's projected body. Since Jasper was a quite large gem, even by warrior standards, it was obvious that she could take several more months to reform. Peridot knew this, after all, she was a Peridot; a technician gem. Technicians were more knowledgeable than warriors and certainly more knowledgeable than a gem who had been stuck on a backwards planet for thousands of years.

"Logically, a Lapis Lazuli could control all water near her, but that is also her weakness." Peridot continued with her audio logging, "If she is not near a water source, she is simply useless." Lapis visibly cringed at hearing this, but she knew it was true. Sure, she could conjure up some small diversions, but she would be no match for any of the Crystal Gems away from the beach. And here? At the bottom of some cave in the middle of dry land? She couldn't even hope to escape.

"Which is why I have been hiding this molecular converter from her, not that it matters much with her stuck in her cell." The green gem grinned as she observed a large machine full of lights, switches, and tubes. "A bit archaic, but this machine can allow the gem to take advantage of the water vapor in this planet's air, giving Lapis a direct power source. With the amount that this machine can pump, it should be enough power for Lapis to at least disable the Crystal Clods."

"Of course, until now I would never give such an unstable gem so much power." Peridot walked over to a large mainframe computer, "But with me in control, what could go wrong?"

Lapis was out of earshot when this was said, but she could tell that Peridot was up to no good. Why else would she be talking about Lapis Lazulis? The prisoner gem was at least happy that the warrior was not yet back, the abuse that Jasper had dealt to her was…

"I can wait them out." She sat determined in her cell. Lapis had already been prisoner for thousands of years, this was like a drop in an ocean for her. At least she had some entertainment, as Peridot would sometimes become furious at Lapis' lack of response. Lapis was tired from fusion, she was tired of Peridot's voice, she was tired of Jasper's abuse and machines and technology, but most of all, Lapis was tired of being a prisoner.

"Maybe I deserve a rest." Lapis had heard Steven say something about sleeping, perhaps it was time she tried it for herself. As she lay on the cold, hard floor, curled into a ball, she thought of the boy once more. She truly missed him and his personality. He was the one thing she could say that she missed other than being free. He was one of her only comforting thoughts, now that she knew Homeworld was a bust. She rolled over so that her back was facing the cell "door".

"What's wrong Lapis, you upset about something?" Peridot asked in a mocking tone, "I'll give you one last chance to help me end the Crystal Gems." Lapis slightly budged at this notion. She truly wanted to destroy the Crystal Gems; they kept her prisoner for thousands of years and if not for Steven, she would likely still be trapped in that damn mirror. They were traitors to their own kind and committed the highest degree of mutiny, how could she not hate them? The only reason that she was hesitant to fight them was because she didn't want Steven involved. Of course, she still would never agree to help Peridot. Lapis never trusted the green technician and for good reason; she was aligned with Homeworld, a place that scared and confused Lapis. If Peridot was successful in her mission, then Lapis would be going back to that place as a prisoner, not as an equal gem.

"Arrg, you clod!" Peridot yelled in annoyance at Lapis' noncompliance, "This is the last straw, you broken piece of trash!" Lapis chuckled at Peridot's outburst, these outbursts were her only entertainment and Lapis found them far funnier than she was letting on.

"RRRRRG!" Peridot shrieked even louder than before, "You think you can get away with humiliating me over and over again? You do it, Jasper does it, those crystal freaks do it, is this some kind of game? Well this time, I win and you lose! You're going to help me whether you want to or not!" Lapis felt slightly unnerved at those words, but brushed them off. Peridot was just blowing off steam at this point. After a few more minutes of 'blowing off steam', Peridot walked back over to her machines leaving Lapis alone again. A little later, Lapis had fallen into a deep sleep, the first she has had in countless years.

"WAKE UP, CLOD!" Was the first thing that Lapis heard in the morning, "Time for you and me to have some fun…" Peridot sneered evilly. Lapis was confused, was Peridot talking about fusion? Is that was she was talking about last night during her freakout? That's impossible, fusion is a mutual agreement. Why would Peridot want to fuse with her after the Machalite incident.

"Get her!" Peridot commanded, pointing her finger-cylinders at Lapis. A large tendril launched itself at the blue gem, entangling her in an inescapable force-field and pulling her out of her cell as Peridot turned off the cell's power. Lapis tried to struggle free and use her powers, but it was no use. The prisoner could only watch as she was forced across the cavern to a metal table on the opposite side.

The tendril wasted no time in forcing Lapis onto the table; strapping in her arms, legs, and neck with the same green energy used to contain her in the cell. Peridot grinned as she witnessed her machines do their work, chuckling slightly at Lapis' predicament.

"You thought you could make a fool out of me?" Peridot grinned, anticipating Lapis' reaction to the upcoming events, "Even though you're a Lapis, you're just an archaic piece of trash like those crystal clods." The green gem sneered at Lapis, clearly pleased with herself. "Even so, I have to admit that you are much stronger than me, especially on this planet."

"What are you going to do?" Lapis finally spoke to Peridot, her voice cutting through the air like a knife through warm butter, "Try to fuse with me?" Peridot looked at the blue gem with disgust, almost appearing revolted. The idea of fusion was unappealing to any homeworld gem, but Peridot had an especially negative opinion of it. She was taught that technicians should never fuse, for their purpose was not for direct combat, but for managing machines and robots.

"Fuse? Me?" Peridot acted as though she had to throw up, "I would never 'fuse' with any gem, much less trash like you. Fusion is for weaklings and fools, Jasper made a mistake when she fused with you." Lapis almost appeared upset by this answer, but didn't say anything more to the green technician. Lapis was relieved in a way, her struggle with Jasper had nearly driven her mad.

"No, fusions are unstable and unpredictable." Peridot reasoned, "Too many things can go wrong. What I have planned is much more controlled and stable." Lapis raised her eyebrows, this was the first time that Peridot had acted so odd since she was recaptured. For the most part, Peridot mostly kept to herself and her machines. Every now and then she would bother Lapis, but that was relatively uncommon.

"More machine stuff." Lapis looked slightly disgusted at Peridot's tendril that was currently plugging itself into the table to which the ocean gem was bound. "Why does it always have to be machines…" She said to herself, looking more afraid by the second as the table displayed a holographic screen at her legs.

"Let's start this slowly," Peridot grins as she thrusts her hands into the holographic display, her eyes becoming a mesh of blues and whites, "20% power!" The machine whirred to life and Lapis felt something strange. She began to notice the air around her and its inherent water vapors, feeling that she could control a small portion of it. "Water...There's water everywhere!" Lapis beamed, feeling more confident than ever. If she could now remove her primary weakness, this prison couldn't dare try to hold her. She could feel the water in the air falling under her control as she moved and condensed it into a visible liquid.

"Ok, now for my favorite part!" Peridot screeched as she thrust her hands even deeper into the control panel. "Controlling you!" Lapis felt a sharp surge of pain and then nothing. She could still see and hear perfectly fine, but she was no longer in control; that dunce Peridot was. Lapis began to panic, this was new. She had never heard of gems using mind control before, but of course she had been trapped for thousands of years in that mirror. Or all she knew, this was basic gem tech, but something told her otherwise.

"So much power!" Peridot screamed in glee as she invaded the mind of Lapis, "More, more, more!" The blue gem felt a strong pain in her gem as her perception to the water vapor grew and grew. Lapis began to scream as the piercing pain overtook her and her body. Peridot had created a miniature hurricane out of the air in the cave, just to see the power.

"Yes! Yes!" The power increased yet again and Lapis arched her back as her other senses were dulled. This was too much power, her gem simply couldn't handle it. Outside the cave, storm clouds began to form and water poured down from the sky like a faucet. Lapis could now control other elements besides water.

"Peridot, stop!" Lapis began to yell out, hoping the other gem would have at least a shred of empathy, "Please!" Peridot looked into the eyes of the prisoner.

"Are you kidding? We're just getting started!" Peridot turned the power up another notch, "FULL POWER!"

"NOOO!" Lapis screamed at the top of her lungs, her gem beginning to shake. She was more than scared now, she was terrified. What was happening to her gem? She could now sense other concepts, including space and time. This was far beyond Peridot's wildest dreams; a veritable goldmine of power, who would've known?

CRACK!

Peridot frowned as she saw Lapis' eyes lose their light and turn back into soulless white disks. This was not part of the plan she had in mind. Perhaps she had gone too far this time, after all, what use was a cracked gem?

"ARRGH!" Peridot screamed at the gem, "STUPID CLOD, I WASN'T FINISHED WITH YOU YET!" In her anger, she turned the power up yet again. This was an accident, the machine wasn't designed to handle more than what she had used it for.

Peridot's head turned when she heard a rip, but not from anything physical. This rip was a rip in space; Lapis' power had reached a truly dangerous level and even Peridot was having a difficult time controlling her. Lapis' screaming had not ceased since she had cracked, but now even Peridot was getting worried about taking it too far. The machine would not respond when told to turn off.

RIIIIIIP

A large contraption in the corner of the room had completely disappeared. Peridot started to panic now, she had no clue what she was doing. Even Peridot had no clue what these rips would do if they hit a living gem. Whatever the result, the technician was sure she wanted no part in any of it.

Lapis had no feelings but pain. She could sense everything and anything, but her powers had no direction. She was in too much pain to be afraid, too much pain to feel anything.

RIIIP

Without warning, Lapis' pain ceased and her body was plunged into an endless fall. Everything around her was pitch black, but she could tell that it was not natural. Did she shatter? Is this what shattering felt like? A sweet release? She shook her head and decided she could wait. She waited through her imprisonment by way of crystal gems, Peridot, Jasper, then Peridot once more. She could do this. She was good at this. Whatever was coming, she would be there.

All she had to do was wait.
