Humanity is beset by strange beasts called Grimm, on the small but technological world of Remnant. Magic-like Dust lets humanity fight in physics-defying ways.
Type: Blossom
Dust is an elemental substance mined on the world of Remnant. It allows someone, properly-channeled, to create elemental effects or empower things with an element. Dust is a fuel and an enhancement, being used to power many devices in Remnant.
Most technology on Remnant is similar to late 20th or early 21st century Earth. Refrigerators, trains, and so on. Airships are common, but fightercraft less so, and worldwide communications are not as stable thanks to the threat of the Grimm. They do exist, but are often expensive.
Personal devices called Scrolls provide PDA-like functionality, and more advanced tech like robots and fully functional prosthetics exist. Spacecraft and satellites do not, which is one reason that making a reliable communications network is so difficult.
A small percentage of the population on Remnant is not entirely human, but faunus. These people have a single animal feature, better night vision, and sometimes an animal-related talent like chameleon skin. They are a minority that has had difficulty integrating with most of the population for decades, and strife or prejudice between humans and faunus is common. This is becoming less common of late, but extremist elements still exist.
With the Blossoming of the world onto the World Tree, some faunus are urging for migration to more tolerant worlds. Ironically, the threat of even stranger beings has begun to make many of the humans of Remnant more tolerant of faunus, as they are at least natives of the world.
Dangerous beasts called the Grimm roam Remnant. These creatures hate humanity(including faunus) and seek to destroy it, and are drawn to negative emotions like envy, hate, and sorrow. They resemble normal animals, but with a more combative twist, and some of them are much more fantastic and dangerous, resembling wolfmen or even more exotic beasts that would be mythical legends in other worlds, like the manticore. Some have unique skills, as older Grimm gain greater toughness and abilities. They tend to dissolve once beaten, making them difficult to study.
Throughout the land, several schools train the best and brightest of their nations to be Hunters and Huntresses. These elite fighters are meant to protect humanity and the cities from the threat of the Grimm, and specialize in hunting them.
Hunters often have a changing weapon with multiple modes of attack, and highly-developed powers that are almost magical in nature, using the internal energies to create duplicates, super speed, sonic attacks, or other more subtle effects. They are highly skilled and capable of taking on multiple elite troops, but sworn to protect against the Grimm.
