This page refers to the key lore and world setting within the BlazBlue franchise. These are only brief summaries of each concept, and more can be found within the respective articles.
Universal Lore
This refers to lore which relates to all media within the franchise
Azure
The Azure is at the centre of the BlazBlue franchise. It is an omnipotent force that can grant the wishes of anyone who obtains it. It is mysterious and much is unknown about it. BlazBlue is essentially the stories of those who attempt to claim the Azure and the events that unfold.
It rests deep within the Boundary.
Embryo
An Embryo is a crystallisation of Azure that is formed from thousands of souls. It has the power of Phenomenon Intervention and is capable of turning into anything, such as a world or even a person.
Soul
A soul is the essence of what makes a person, and is possessed by every living thing. In the BlazBlue franchise, the concept of souls and their properties are part of the motives of certain characters. All souls return to the Azure after death.
Possibility
A Possibility refers to the many different parallel worlds which run concurrent to one another. There are three major possibilities: the BlazBlue possibility, the XBlaze possibility, and the Bloodedge Experience possibility.
Media and stories within the BlazBlue possibility include: BlazBlue: Calamity Trigger, BlazBlue: Continuum Shift, BlazBlue: Chrono Phantasma, BlazBlue: Central Fiction, BlazBlue: Remix Heart, BlazBlue: Variable Heart, BlazBlue: Phase 0, BlazBlue: Phase Shift 1, BlazBlue: Phase Shift 2, BlazBlue: Phase Shift 3, BlazBlue: Phase Shift 4, BlazBlue: Chimelical Complex, BlazBlue, and BlazBlue: Alter Memory.
Media and stories within the XBlaze possibility include: XBlaze Code: Embryo, and XBlaze Lost: Memories.
Media and stories within the Bloodedge Experience possibility include: BlazBlue: Bloodedge Experience - Part 1 and BlazBlue: Bloodedge Experience - Part 2.
Logic
Logic is a fundamental set of rules that the universe adheres to. All things exist within Logic, with the exception of seithr and certain creatures. Arts were made to counter beings that exist outside of Logic. Anything created with an Art exists outside of Logic, such as a flame made with magic.
Boundary
The Boundary is a dimension that exists outside of time, and is the place where all possibilities intersect. Seithr exists in limitless quantities within this dimension, surging out into the world through cauldrons. Unless extraordinary precautions are taken, most biological material cannot survive the Boundary as it gets corrupted by the vast levels of seithr. The Azure rests deep within the Boundary.
Cauldron
A Cauldron is an entrance into the Boundary. Seithr spews into the world from these locations, which are usually deep underground.
Seithr
Seithr is a substance which is used to fuel most Arts. It is a particle substance which constitutes every living thing and usually exists in a gas like fuel. It is usually invisible but can be seen in thicker quantities, where it is poisonous. Seithr can mutate living creatures and surges out of the Boundary.
Art
Art is the umbrella term for all abilities, powers, and techniques which require seithr to function. Some of these Arts are exclusive to certain possibilities, while others are universal.
Universal Arts include: Sorcery, Magic, and Alchemy.
Sorcery
Sorcery is an Art which does not require seithr, and is the only one that does need it. Using mana, the essence of nature, a sorcerer can manipulate the world around them, creating fire, lightning, light, etc.
Magic
Magic is an Art which requires seithr. It is functionally similar to sorcery.
Alchemy
Alchemy is an Art used to make bodies, souls, and objects more perfect. It uses scientific principles in order to function.
Drive
A Drive is the physical manifestation of the soul, allowing Drive users to employ powers unique to them. Only the strongest of souls are capable of manifesting a Drive.
The term Drive is also used in the C-Series gameplay to refer to a character's unique mechanic.
Sankishin
The Sankishin are three entities that are the equivalent of gods. Each one deals with an aspect of time.
Amaterasu Unit
The Amaterasu Unit governs time, and is capable of both major and minor phenomenon intervention|.
Tsukuyomi Unit
The Tsukuyomi Unit protects time, and makes a large shield that repels any force when activated.
Susano'o Unit
The Susano'o Unit slashes time. It is a large set of armour that makes the user impervious to the Boundary.
Onlooker
An Onlooker is a powerful individual who can watch events unfold yet is unable to directly intervene. They are immune to phenomenon intervention but are capable of employing it. They can remember events and circumstances, even if phenomenon intervention has been used to change them.
In the English localisation, this term was merged with Observer.
Observer
An Observer is a person who can employ phenomenon intervention to discreetly manipulate the world around them. They acknowledge a similar possibility and enforce their will upon it in order to make it reality. There are great risks associated with the power, and there are limits that the average Observer must adhere to.
Phenomenon Intervention
Phenomenon Intervention is the ability to discreetly change the world around them. The power is employed by Observers and Onlookers. Minor phenomenon intervention can be used by the average Observer, such as changing what they had for breakfast. Major phenomenon, such as if someone falls down a cliffside, can only be changed by certain individuals and Observers, such as the Amaterasu Unit.
