The Coal's had been created on Earth for around 1000 years and had been mistreated for the entire time that they were created. They were put to work as soon as they were created and taken to Homeworld when they could no longer work, either because of them becoming injured or if they became to tired. All Coals had a the same height which was about the same height as a Ruby and their build was fairly well built for their manual labour. One Coal that was created was different however she was more resilient then the others, she was always trying to run away or escape. This angered the gems who were in charge of keeping the Coal's in check and despite how much they just wanted to shatter her they were under strict orders not to. The rebellious coal was seen as a leader to the others she was kinda to all of them and protected them even trying to fight the Quartz's when they came to gather the Coals up.

One day she formed a small group to escape with, each of them had a coal in a different placement on their forms with different personalities. One was called Armani because their coal was on their arm, another was called Basira as she had a coal on her head and was the most intelligent of the group, another one was called Bruno as he was the one who always seemed to protect the leader and then there was Cora who had their coal on their heart who acted like the child of the group. The leader of the Coals never chose or was given a name and was always just called Coal as she was seen almost as their embodiment of what the best a Coal was.

 When the group had finally escaped they ran for a few nights and days learning more and more about the planet they were never allowed to explore. They came across strange new animals and creatures called 'Humans' most were alright from what the Coal's could see but some were aggressive and hurt the earth or the other humans. After travelling for a few months learning how to defend themselves they ran into the crystal gems the Coal's had always been told of the gems and were told to kill them on-sight. However, when the Coal's saw the Crystal gems they bowed their head's in respect the main leader even going to one knee in front of Rose. From that day on the large group of Coal's fought alongside the Crystal gems in hopes to free the rest of the Coal's one day. As time went on the gems had gotten close with every single one of the Coal's and the leader of the Coal's had gotten very close with Rose they had become best friends almost as close as siblings. But then the dreaded day happened. The day that would change everything.

It seemed just like a normal routine patrol on the abandoned battlefield the Coal's and Rose were walking through the two leaders talking to each other about what the plan was when suddenly a large ship landed in front of them. The gems pulled out their weapons and aimed it at the ship a large orange Jasper exited the ship and laughed at what she saw.

"So Rose, your army has been forced to recruit Coal's now?" The leader of the Coal's walked forward and aimed her sword at Jasper. "Aw what are you going to do?" She looked back into the ship and turned back. "Quartz's attack!" Suddenly a large group of Quartz soldiers emerged with their weapons attacking the group. After what felt like hours most of the Homeworld gems were defeated when Jasper jumped in and summoned her helmet making the Coal's step back slightly in fear apart from the leader who stood her ground Bruno looking at her worriedly. The leader of the Coal's went to defend her people when she saw out of the corner of her eye that Rose was going to the warp pad. Coal skidded to a stop and turned to where Rose was.

"Rose!" Rose looked back. "Don't go! We can't do this without you!" Rose sighed and kept walking. "No! If you leave you'll be sentencing us to death!" Rose didn't stop though and in a second the Coal's went silent as Rose disappeared. Jasper laughed mockingly.

"Even Rose Quartz thinks you guys are worthless!" This made the leader yell in anger and she swung her sword at Jasper. She defended her people with everything she could but it wasn't enough. Jasper swiftly grabbed her by her hair and pulled her into the air before anyone could do anything Jasper was repeatedly punching her in the gem until cracks were forming Bruno saw the cracks and tears pricked his eye as he started running towards them in hope to save her. He was to late. After one final punch she let the shards fall to the floor.

"Finally, that mistake is taken care of" She see's the remaining Coal's looking at her terrified, except for Bruno and Armani who were glaring daggers at her wanting to shatter her. Jasper smiles evilly noticing a cave behind her she had a Peridot do research on the area before they arrived and if she got the right area then.. after punching a hole in the ground she saw a large cave system with natural human crystals growing around. The remaining Quartz's gathered the Coal's and threw them in the hole the Coal's gems were not damaged but they received injury's on their physical forms. Before Jasper left she dropped the leader of the Coal's gem shards down the hole. "Enjoy burying your leader" and with that she was gone leaving the Coal's abandoned in the unknown cave system. Some were scared, some were angry but all of them were sad for the loss of their leader. They sat their for days thinking that the Crystal gems would come and find them when Armani stood up yelling.

"This is pointless they are not coming to find us!" Cora stood up timidly holding her arm sniffling back tears.

"Yes they are. They have to be looking for us!" Armani glared at Cora.

"Oh so when Rose abandoned us to retreat she was gonna come back?!" Cora looked down. "And what's worse is because of Rose our own leader is dead! And she is never coming back!" This was when Basira walked forward.

"Actually that may not be true" Armani and Cora looked at her in shock. "You see when everyone else was sat here mourning I made some calculations and as you can see here" She then went into saying lots of scientific words that no-one understood making Armani say.

"Wha?" Brain sighed and pinched the bridge of her nose.

"Basically if we focus all of our life forces together and transfer them from our Coal pieces we can put them into the shards left from our leader. We can make the ultimate coal" Armani raised their eyebrow at Brain.

"But why would we all agree to basically die just to let our leader live and be alone forever?" From behind the three of them Bruno walked out of the shadows holding Coal's shattered pieces smiling evilly. 

"Because then she can get revenge against Rose Quartz for us all" This made all of the Coal's smile and nodded their head's in agreement. They placed the shards next to each other like a puzzle and they then stood in a circle. Soon all of their coal pieces were shining together making them scream in pain but they kept going when they saw their leaders coal piece lifting up pieces of electricity shot through the shards making them stay close together. Suddenly, a bright light engulfed the cave system and none of the Coal's were left. Well all except one the only Coal that was originally shattered the leader of the Coal's but she wasn't like she was before. Her body pieces were broken and off her legs and arms were separated from her body only being held together by purple pieces of electricity. Her fingers were as sharp as knifes and were not attached to her hands (think of Peridot's limb enhancers) her coal piece was still shattered but was held together by purple electricity. Finally, her head was also detached from her body (A/N for the shape of it search Bendy from Bendy and the ink machine) her eyes were black and devoid of happiness and she had sharp teeth. She placed her finger's on her head as she freaked out.

"What has happened to me? why am I like this? where are the others? who did this-" The questions stopped when she suddenly remembered Rose. She abandoned her and her friends. No. Her family. The anger seethed through her when suddenly her face began to hurt like a fire had been set on her face. She ran to the nearest pool of water and saw her face was cracking it was only a little one that had appeared in the top part of her eye. "Okay. Note to self manage anger better" She sat their alone in the cave when she began to cry she wanted to see her family again when she imagined Heart and Army and Brain and all the other her coal piece began to shine brighter then ever and it suddenly shot projections around her showing her the forms of her family. She kneeled down (in this form she is as tall as Jasper) and placed a hand on its shoulder her hand going through it. "I promise all of you I will get revenge and I will not stop until I do."
