Remnant, a mysterious yet dangerous world full of soulless creatures called Grimms. They say Grimms are evil beings that feel no emotions, they're only purpose was to kill. But, what if they're wrong, a girl that can tamed them. Follow her and her friends as they embark on a dangerous journey, meeting new friends and enemies and stopping a great evil that was coming.

Remnant

A world that is filled with mystery and danger. Remnant has existed for hundreds of years. The lands were beautiful yet dangerous. Remnant was created by two gods. Brothers to be exact, one older and one younger, they both existed on Remnant, filling it with both life and destruction. The two brothers have different ideas about how things should go. The older brother, the God of Light, found joy in creating forces of life. He created water, plants and wildlife during the day. But at night, the younger brother, the God of Darkness, spent his time creating forces of destruction. He finds his older brother's creations repulsive. He created drought, fire and famine, all that he could do to rid Remnant of life, yet life always returned. Nothing can stop life from returning, so the god of destruction decided to create creatures that can destroy life. And on that night, the younger brother created the creatures that shared his innate desire to destroy anything and everything on their path, and he named his creations Grimm. The Grimm or the Creatures of Grimm are beats of destruction and death, not caring the consequences that would happened.

The older brother finally had enough of his younger brother's behavior and destructive mind. He knows that their feud wouldn't last forever, he proposed that they make one final creation together, something that they could both be proud of, and to be their masterpiece. And the younger brother agreed.

Together, they created a creature that was gifted with knowledge, creation, destruction and choice. Most important was the capability of choosing whether to use these gifts for light or darkness. These creatures became known to be Humanity. Once they finished their final creation, the two brothers left Remnant, allowing humanity to choose their fate, not knowing about the truth of the gifts that they left behind.

Humanity or better known as Humans are the two brothers' greatest creations, they learn and understand their surroundings before they started to make their own lives. They soon learn how to defend themselves from Grimm. They soon discover Aura. An ability that all those with a soul can use, at least with enough practice. This also gives them Semblance, ability that is unique for all. They even learned the use of Dust and how to weaponize them in combat and defense.

Soon, they build four kingdoms of Remnant, Vale, Vacuo, Atlas, and Mistral. Each of the kingdoms has their own distinct culture. The four kingdoms have Huntsman Academies that trains people to hunt and fight Grimm. These Academies help them to become great huntsman and huntswoman. They trained to be best and protect others. These Academies are found in each kingdoms'. Haven Academy of Mistral, Shade Academy of Vacuo, Atlas Academy of Atlas, and Beacon Academy of Vale.

These Academies brought protection to the kingdoms and brought peace, but there were a times when peace was soon turn to war when humanity fought against another creature called Faunus. Faunus are like humans but with animal features, they are more skilled and well advance species. They were treated badly because of their animal like features, thus the humans treating them like animals. The Faunus and Humans fought each other for years, causing the Great War.

Many bloods were spilled in battle before they brought into truce. Faunus were allowed to have equal rights, but they were still discriminated by humans, but some humans treated them with respect and treats them fairly.

Over the years, the Kingdoms remained in peace and would have the Vytal Festival. The Vytal Festival was inaugurated following the end of the Great War. It's an international festival held every two years in one of the Kingdoms of Remnant. During the festival, various cultures of the world are celebrated with dances, parades, and a combat tournament. The host kingdom of the festival rotates every two years, and the host opens its borders to visitors from the other kingdoms.

Even though those four kingdoms are in unity and somewhat in peace, there was one Kingdom that was hidden from the rest of the world. An ancient species that is known to be dangerous and mysterious. The clan was called Grimm Riders. Grimm Riders are the only ones that can tame and control a Grimm.

They're origins were unknown to all, but legends say that they were made by a Goddess named Lunaria, she is the Goddess of the Night and Stars. She watched from above as the Grimms terrorized the kingdoms and kill without reason. Humans and Faunus have to feared and hated them, they couldn't even get close to the Grimm. Saddened by this, Lunaria wanted to help them understand, and that's when Lunaria had an idea to make humans and Grimm to live in peace. Not only she's the goddess of the night and stars, she is also the goddess of wisdom and emotions. She would give some humans an ability to understand Grimm without any fear. So, using her magic, she gave the gift of knowledge and understanding to ones who have the mark, the Mark of the Grimm.

The first bond with a Grimm started by a little girl by name Nisha Midnight. Nisha was born with a strange black mark on her back. A dragon symbol to be exact, it was dark as night and the eyes were red as fire. Her parents didn't seem to be bothered by the mark, but kept it hidden from the people. Nisha grew up in a poor village with a bad leader. The village has few foods to spare and the villagers there are greedy and selfish, yet Nisha was able to survive with the help of her parents. Her parents were not like the villagers, they are kind and generous, and they took care of their daughter the best way they could and keeping her safe.

Then one day, everything changed, when Nisha went to forest to pick some berries and came face to face with a Grimm. The Grimm she has seen was a Dragon Grimm. It was rare of all Creatures of Grimm. It was bigger, meaner, and deadlier. It came to her village to attack, but it didn't. It soon formed a bond with the little girl. The Grimm Dragon didn't attack the village of Nisha's, but it did spend time with her as she talks to it and plays with it. The Grimm and the girl became close, but the dragon had to leave, and it soon left, while the little girl waved goodbye at the Grimm Dragon.

But she didn't know that there were some people who witness her ability and soon believe that she was a monster. When she returned, the villagers grabbed her and tied her to a post on the center of town, the people who had witness her with a Grimm believe that she was a monster that must be killed. They stoned her parents to death for being the parents of the girl. The girl was frightened by this, she watched in horror as her parents were stoned alive. The village leader ordered the villagers to ready the fire to burn her alive. The girl was so scare, her eyes filled with tears as she prayed for a miracle. The village leader ready a torch to burn the child, but she lets out a scream that was so loud, it was heard by miles. Before the village leader could burn her, everyone heard a blood chilling howl from the forest. Everyone froze in fear as they all turn towards the forest. Hell fired eyes were seen in the shadows, the villagers panicked. The villagers panicked at the sight, they realized that in the shadows were Grimm.

The Grimm are drawn to negativity feelings such as envy, sadness, anger, loneliness, fear, and hatred. But the Grimm were not drawn by that, no. They were drawn to the call of the little girl. Her cry was heard from them, and they were drawn to her, because she bears the Mark of the Grimm. Without hesitation, the Grimm attack the villagers with bloodlust, the humans tried to escape, but the many Grimm came and killed them all. The leader tried to escape but was stopped by the Grimm Dragon. It came back when it heard the girl's cry, the Dragon Grimm ended the leader's life with one gulp. A Grimm that look like a wolf known as a Beowolf went towards the girl and cuts her free. It took her out of the village while the rest of the Grimm killed all the humans that live there. The girl has no home and no family, she was alone…well, not all alone. She has company, many company. She was accompanied by Grimm. Many Grimm became her friends, she can understand and feel them. She soon was able to bond with them and learn that they are tamable while some were not, she called the not tamable ones: Rogues, because they are not like the Grimm that she bonds with. She grew up in the wild, learning from what she experiences in the wild and watching nearby village from afar. The Nisha learned how to survive on her own, with the help of the Grimm. But, Nisha felt lonely since she was the only one who can talk and understand the Grimm, and felt like she was the only one who can be one with the Grimm.

Or so she thought.

The goddess, Lunaria, made others like her. They were in other lands and were currently afraid of what they are. Nisha soon discovers them and helps them with their new found powers. Soon, they called themselves the Grimm Riders because their ability to tame and understand Grimm. They travel endlessly on Remnant, trying to find a place call home since no kingdoms will welcome them and because they were outsiders. They almost lose hope, but soon Nisha discovered that she has a gift, a gift of vision. She could see the past and the future. She discovered it when she turned thirteen. Nisha learns the true origin of who she and the others are, and knows why they were here. Nisha knew that they were made to do something good. So, using her vision, Nisha leads the Grimm Riders to a safe island, far from Remnant, far from Humans and Faunus, far from danger. The Nevermores and the dragon helped them reach to that island. The island was filled with Grimm and rich with Dusts. No Humans or Faunus could find it because the water was filled with aquatic Grimm that can destroy them. There, Nisha and the others build their own kingdom. Nisha and the others worked together to build the kingdom and with the help of the Grimm, they did it and it was called Tenebris.

That Kingdom was their sanctuary, their home. They made sure that it stayed hidden from the rest of the other kingdoms. It was there they discovered a special red gems that can store their tame Grimm and turned them into miniature versions of themselves. The craft the red gems into necklaces, earrings, bracelets, armbands, beltbuckles, and more. They called it the Grimm Befrienders, it helps them carry and hide their Grimm. Their Kingdom, Tenebris, protect them from the outside world. But the Humans heard rumors about their island's existence and tried to find it and get a hold of their fortune, but they end up missing or lost if they ever tried to find Tenebris and Grimm made sure of that the invaders don't ever come near Tenebris. The Grimm Riders trained themselves to control their ability and their Auroras, and weapons to defend themselves from invaders or Rouge Grimm.

Even though they have a kingdom now, the Grimm Riders are missing one important part of their kingdom, a ruler. Other kingdoms and villages have their own rulers and leaders, but they don't. They needed someone who is worthy, kind, wise, and strong, to be their leader. It didn't take long for them to decide, considering they know one person who was perfect to be their ruler.

Nisha Midnight

Nisha became their leader, their Queen, when she was only sixteen. At first, she was shocked by this, but learned that she was destined to be a leader since she was the first Grimm Rider and the one who lead them here. Nisha became the Queen of Grimm Riders, guiding her people and protecting them from danger with the help of her dragon she named Ash. Then the Grimm Riders build their own academy called Umbra Academy, where they trained new generation Grimm Riders to learn and control their abilities, and make their weapons. They made laws on their island, and one particular rule is that if a Grimm Rider reach to the age of sixteen, he or she are allowed to leave the island to explore and learn any changes on the other kingdoms, and return when they are done. Adults were allowed to leave freely, but made sure to stay hidden and get information for Nisha and her people. The Grimm Riders never betrayed their own kin, they will never reveal themselves to any outsiders, and made sure to keep their home a secret. Nisha has no intention of bringing war on other kingdoms for treating them like outsiders. She believes that if it wasn't for them, she would never been queen and never finding the Grimm Riders. And as the Queen of Grimm Riders, she will do no harm on others or seek power, she will rule with honor, kindness, and generosity.

The years go by, and Nisha became an adult. She married a man and have a daughter by name Spirit Midnight. Spirit was born Grimm Rider and she inherit her mother's gift of vision. Spirit's Grimm was a Geists that she named Ghost. Spirit was like her mother, she was the heir of the Grimm Rider Kingdom and will follow her mother's footsteps in ruling the kingdom. Nisha will one day leave this world, but she made sure that her daughter. Spirit, will take the throne and will protect her people and their secrets from the outside world. The Grimm Riders' heirs are always born female, meaning that their rulers are queens and they their purpose to protect and guide their people. The Grimm Riders made sure that they must be hidden from the rest of the world, away from society. Time moves on, and the kingdoms have forgotten about the Grimm Riders, yet there were some who knew their existence. The Grimm Riders stayed in the shadows and their safety of their kingdom, and making sure that new generation Grimm Riders were born at Tenebris.

But, their was one Grimm Rider that was born outside of the island and doesn't know why she was there.

This is her story.
