Nightmare is a special Grimm that grows by absorbing aura, possessing humans.

The Four Maidens are from a fairy tale called “The Story of the Seasons”. In Remnant, the story is told but the four sisters are believed to be pure fiction.

The world of Remnant is the backdrop for all the events in RWBY. It is not unlike Earth with various climates, multiple seasons, a single (albeit damaged) moon, enormous cities, small villages, and an abundance of living creatures. Every facet of life on Remnant — down to its settlements, culture, and technology — is a direct result of the constant struggle between Man and the destructive, soulless Creatures of Grimm. With these dangerous monsters roaming every continent in vast numbers, the threat of the Grimm has forced the people of Remnant to cluster together in areas that are easily defensible and offer natural protection.

Huntsmen and Huntresses are the best and brightest warriors of Remnant – and its most powerful defense against the Grimm. It’s a dangerous profession that requires a license to practice, which is only granted to those who complete the rigorous training at one of four Huntsmen Academies around the world — Beacon, Haven, Atlas and Shade. Once granted a license, their duty is to serve and protect all mankind. *A male license-holder is a Huntsman, female license-holders are Huntresses.

An Aura is the manifestation of the soul — the life force that runs through every living creature on Remnant. Since the soul is what makes an Aura even possible, creatures that are not considered living, such as the Grimm, do not possess Auras. With the proper training, true warriors learn how to amplify and control their Aura, harnessing its more powerful abilities.

A Semblance is a tangible manifestation of one’s Aura. It’s is unique to each individual. Telekinesis, super speed, teleportation, mental illusions, shadow clones — all of these are examples of an unlocked Semblance. In some cases it is also possible for a person to use their Semblance in conjunction with Dust.

Summoning Glyphs is one of the applications of a Semblance that has been passed down through the Schnee family for generations. Their unique Semblance allows them to summon an enemy from a glyph that has been defeated in the past. Weiss Schnee is still learning to master this ability.

Dust is a primary energy source in Remnant. Found naturally in a crystalline form, Dust is mined from all over the world. Not only does it power every facet of the world’s technology, it can also be triggered by the Auras of Humans and Faunus for use in battle, and has proved to be the most effective tool for combating the Creatures of Grimm. Dust occurs in a variety of colors and types, but is primarily found in four basic forms. The most basic forms of Dust are Fire, Water, Lightning, and Wind.

The Faunus are a human-like species who reside in Remnant. They are set apart by their animal traits such as cat ears, monkey tails, tiger claws, and bull horns. While physical traits among Faunus vary, many may also display heightened senses of sight (such as night vision), hearing, or smell. Faunus and humans have lived together for centuries in varying degrees of harmony. However, longstanding grudges and prejudices still exist in certain parts of Remnant.
