Long ago, two races ruled over earth: humans and gems. One day, war broke out between the two. After a long battle, the humans were victorious. They sealed the gems underground with a magic spell. Hundreds of years has passed after the before mentioned events.
Legends say that those who climb the mountain never return. A young child could be seen at the mountain's doorstep, inside what looked like a small hideous cave; the human tripped and fell down a hole inside the mountain. After landing, the recently fallen down child was injured, they cried for help; someone, anyone, to rescue them. When the human almost let out their last plead for help, a massive, powerful looking figure came close. The odd looking person came in aid to the kid's call. She was an immense, mostly pink colored individual, with a strange type of rock stuck to where her navel would have been. It indeed, was a gem. Clasping both of her hands together while leaning down to have a better look of the wounded fallen, she spoke with some concern. Her voice was soft and light; relaxing, calm. "Are you alright? Did you fall down from the hole up there?" The child softly nodded, with their eyes pseudo closed as blood was running down their face. Without hesitation, the pink colored individual carefully took the human with one hand and started walking away of the place. The grasp was firm but not tight.
Hours later, the fallen could be found resting on top of an oddly gigantic pillow inside a room filled with flowers. The scent was marvelous; one could say that this might had been the mysterious figure's room. "I hope this helps you a bit. These flowers' scent is said to have healing properties. So, for now you should better rest here." She expressed with both arms crossed and a worried look. And she was right, those flowers were capable of healing someone with just their sweet, strong smell. The human fell asleep; their condition was slowly stabilizing. As for the wounds, those were steadily healing thanks to the child inhaling the flowers' smell while sleeping.
Days later, the unknown fallen was successfully recovered thanks to the pink figure's care and dedication. They were able to talk, run, and do anything else a healthy human could do. During a conversation between the two, the child was very intrigued to know about the other's identity. She answered their question with no hesitation; a warm hearted smile formed on her lips. "My name is pink diamond. It's a pleasure to meet you formally." Pink diamond was the massive individual's name.
The young child wondered several times how was the exterior of Pink Diamond's room; what else could be found outside her comfortable, sweet scented place. Without any sort of restrain, the human decided to go outside the room for the first time. They were astonished by such a big place, it was massive and very, very well decorated. Portraits were displayed on every single wall, most of them were showing paintings of all kinds of flowers, such as roses, violets, etc. As they travelled through the place, the human abruptly stopped to contemplate the biggest portrait of them all in an odd decorated room, with strange symbols carved on a massive door besides the painting. The image being displayed didn't just include pink diamond, but other three figures. One had a serious expression while looking at the viewer, she was white almost everywhere. The other two figures could be seen looking on opposite directions, one was blue and the other one was yellow. And on the lowest part of the painting, pink diamond could be seen sitting on top a bed of flowers. Before the human had the chance to wonder who were the other three, they were interrupted; popped the bubble of thoughts. Pink diamond took grasp of the child's fragile body and pulled them close. Her tone of voice was nervous as well she was stuttering. "What are you doing here? I told you to not exit the room!" Pink expressed in concern, was she hiding the fallen from someone? Could it be that she was keeping the young kid's existence? And from who?
Several hours passed. The kid was picking up flowers while waiting for their caretaker to return. When pink diamond entered the room, she looked troubled, exhausted. The child asked her what was going on, to just simply get a short; yet cold response. "Not now, I don't want to talk right now."
Later that day, pink decided to explain the human what was going on, where they fell down, and why she has to keep them as a secret. Clasping both hands together she began to speak with a neutral, somewhat serious tone, which oddly contrasted with her soft and light voice. "You fell down inside a place we call the underground. Not just me but everyone who inhabits this place is a gem. Those figures you saw on the giant portrait are the other residents of this building; they're the other diamonds. White, yellow and blue diamond. I have to keep you as a secret because if they know I'm currently keeping a human here, they will kill you."
The child was perplexed after hearing this, but determined to press further on, they asked something else. Pink at first bit her lips while thinking if she should answer such question, but after enough thinking she spoke. "We were trapped here thanks to the humans, long ago. There was a war between the two of us and they were victorious. That's why I need to hide you, every gem here has a grudge against humankind." Pink diamond expressed with melancholy. "Please, promise me you'll stay here." Pink diamond pledged to the child, filled with concern. The human nodded their head in response to the diamond's orders. For now, the fallen would be kept as a secret to everyone, but is possible that the caretaker might change her mind after enough time has passed.
