Silver-Eyed Warriors

They are an ancient lineage of legendary warriors who possessed special abilities through the usage of their eyes. Their power destroys Grimm and is believed to originate from the God of Light.

Background
The God of Creation gave that power to some humans at some point so they are able to defend against Grimm, however if the lineage continued is purely for natural breeding. They were pretty active during the medieval period but were forced to stop when people started going against them. Nowadays Silver eyes themselves are an extremely rare trait. Reason is because someone is actively hunting them to extinction.

Powers and Abilities
As preservation is considered an extension of creation, Silver Eyes can work against Grimm as they are manifestations of destruction. Legend has it that Silver-Eyed Warriors are able to strike down Grimm with a single look. According to Maria, Silver Eyes can turn Grimm to stone, blind them or vaporize them. The way it works are pretty use to understand if you already know the basics. The Silver Light is just the method to carry particles capable of affecting the Debran, an altered version of animura that makes it negative and only Grimms possess. They are also capable of damaging species hybrids if they are part grimm.

Limits
The rarity of the trait has left much of the abilities of Silver Eyed Warriors only vaguely detailed in old stories due to the active hunt against them. Upon using the ability for the first time, the user might lose consciousnesses, their head hurt while using their eyes, showing the light drains the user's energy in the inexperienced.

Upon being used, the user is not invulnerable to being hurt or interrupted, obviously if they lose their eyes, they are incapable of ever using those abilities again. Much like how a Semblance can be affected by strong emotion, Silver Eyes are susceptible to reacting to intense distress.

The Heroes of the People
During the medieval time of Remnant when Huntsmen and Huntresses weren't that common, people was a lot more vulnerable, and the grimms were capable of erasing entire villages easily if needed. When life was dark, the silver-eyed warriors stood up becoming the guardians the people needed, at beginning they just used their eyes but with the time they became highly trained and strong, being able to carry out with their duties more effectively. These warriors were loved and admired by everyone.

Silver God Alliance
With time, the silver-eyes warriors noticed the existence of another group, the "Children of God" who had gained power and notoriety by putting themselves about everyone else. They disagreed with their act but didn't go against them because they were busy enough with the grimms, however the other group declared the war in an attempt to get rid of them to become the most powerful group in Remnant, however, they were clearly in disadvantage as the silver ones had the love of the people, after years of war, the "Children of God" were finally between the wall and sword but they had one last trick, the fear they had already spread on people and they began announcing drought and catastrophes if they continued their path, quickly recovering their position but with a new perspective, the "Children of God" offered a fake mercy to the "Silver-Eyed Warriors" in an event called "The Alliance Silver God". The warriors accepted not for fear but to keep in line the other group from the inside.

The Cursed Eye
Many years after the alliance was formed, both of the groups fused into one officially and short after, the first children Half Child of God and Half Silver-Eyed Warrior were born and their aura were incredibly powerful and were adored by the rest of humans and faunus as the true descendants of God. The alliance "Silver God" earned even more influence in Remnant until one day, one of these new members developed green eyes that looked like the ones of a snake, they started investigating as a rare case but then all of the children started developing the eyes as well. They got more and more power with the time, developing other eyes color when they applied a different level of aura intensity in their eyes, all seemed like good news, their people had a lot more of power but the members of "Silver Eyed Warriors" thought it was terrible, with all that power, the ego of the "Children of God" increased and became even worse than before. A couple generations later the Silver God consisted of three kind of people: the one with the perfect body, the one with the perfect eyes and the perfect ones, but there was a bad news, since the second generation, the new children couldn't change their eyes color and instead had a predetermined aura intensity in their eyes, giving them just one possible color, soon it caused internal wars for dominance and racism between each other. It was obvious they couldn't coexist so each group of people with different eyes got separated and formed their own groups. Thanks to all of this, the people started believing those groups were evil and as kind of curse so they started to being hunted down and executed, which ruined economically to some of the groups, but as if it wasn't bad enough, the groups declared a war between each other for dominance, the only one that didn't want a war were the "Silver-Eyed Warriors" but still got involved in it. After years the first one to be eliminated were the "Pure Ones" as they didn't stand a chance against any of the other groups and the "Silver-Eyed Warriors" dispersed as they didn't want all of them to die in the same place with no survivors like the "Pure Ones".

Fate of the Silver Eyed Warriors
While most dispersed and started supressing their powers. A group remained guided by Allard Bennett, the only Platinum-Eyed Warrior, trying to clear their name and regain the trust of the people, his family was murdered at cold blood making him resentful and abandoning the idea of ever co-exist with the rest of humanity. While they escaped towards a place people wouldn't pursue them, they found Salem. Thinking of her as an enemy first, Allard engaged a fight with her but after clear everything, she offered them shelter, for saving his people, he promised eternal loyalty and only using his eyes for her sake becoming part of the original Inner Circle and the other silver-eyed warriors under him becoming the Silver Assasins.

He served Salem for the rest of his life until he died because of his advanced age. The loyal followers he had were convinced that help Salem was the correct thing to do but they cursed their mortal short life, so the second in command, Luke along with seventy-three other assasins asked Salem to turn them into grimm to keep serving her for eternity. While she had her doubts about the procedure to do that, she finally accepted seeing how determined and serious they were about that. That gave origin to The Hounds. However twenty one members that didn't agree with turning into grimms continued to serve her, making the promise the "Silver Angels" ,which was the new name they adopted, would continue to work under her for as long as their lineage went on.

Both groups were loyal to Salem for centuries, the "Silver Angels" now had white wings because two centuries ago they started breeding with Great Egret faunus to become "real angels" whoever was born without wings and silver eyes would become simple silver assasins working under them. However that group travelled to the Wild Continent for a mission and most of them were murdered by the cult "Grimm Commands". For years the remnants of the group continued to attack the cult sometimes.

Salem did kill some Silver-Eyed Warriors that worked actively against her but most were murdered by Grimm Commands Emissaries.

The Warrior in the Woods
In ancient history, The Warrior in the Woods is a fairy tale describing a lonely Silver-Eyed warrior who secretly defended a small village from the creatures of Grimm, motivated to protect life after her parents had been killed. Whilst defending the village, she meets a young boy several times throughout the years, and inspires him to be better for others. The boy would later find the Warrior's hut thrashed and destroyed, believing that she had died alone. He laments he couldn't be with her, having fallen in love with her silver eyes the moment he met her. If someone saved by her or the boy wrote the story for future generations is unknown.

Modern Days
Silver-Eyed Warriors were able to flourish once again when the Beacons conquered the world as they rescued the Silver Angels Remnants and reunited the ones that dispersed. Since the war was over and the cult annihilated, the hunt against their kind stopped. Flame Fall, the Fourth Beacon of Darkness also posses silver eyes since they were given to her during her creation as she is a homunculus created in the Covenant's lab. A part of The Hounds also survived but they can't use their eyes anymore.

Platinum-Eye
Because of special conditions in both Allard's body and animura. He developed an even stronger version of the silver-eye, capable of dispersing animura instead of debran or in other words, he can desintegrate everything, from objects to even humans, passing by grimms. His son was killed at a young age and he didn't have more childs, putting an end to possibly the strongest branch on the silver-eyed warriors.

Snake Eyes
When a Silver-Eyed Warrior breeds with a Snake Faunus, their children develop the ability to concentrate animura on their eyes, gaining abilities depending on the color, green eyes giving the power to create illusions, call and control snakes (including King Taijitus), extreme flexibility, paralyzing poison (on claws) and lethal poison (on fangs); red eyes giving a lot more of strength and armored skin besides extreme flexibility; blue eyes giving total immunity to poison and toxins, extreme flexibility and antidote to any poison (on claws and fangs); yellow eyes giving a far more effective paralyzing poison (on claws and fangs) and extreme flexibility; and finally purple eyes giving a way more lethal poison (on claws and fangs) besides the extreme flexibility. However, after the second generation they born with a predetermined color and lose their ability to change it at will.

Sapphire Eye
The secret organization Sapphire Dust studied the platinum-eye carefully trying to replicate and failing, however their investigation was able to create the Sapphire Eye by combinating with the sapphire gen they had developed before. While, they weren't able to make the eyes disperse animura like the platinum does, those eyes were capable of create animura interference which can weaken everyone exposed to their light.
