Glossary

Anima Sourcery, or just Anima, is a subtype of Sourcery involving the "life energy" of the Omnicosm. It is similar—but not quite the same—as All Things; whereas All Things is the Omnicosm's "soul", Anima is what gives that soul "life". Anima is just as pervasive as All Things, yet concentrations of "life energy" can differ wildly between locations. Planets rich in Anima like Hyperborea may see spontaneous generations of life through its elements (e.g. Giants, Ember Therion). 

The potential for what kind of life can arise from Anima is as boundless as the Sourcestar itself. With enough Anima, imagination, and power of belief, even regular denizens of the Omnicosm can spawn life (urban legends can be made "real" this way). That being said, beings born of belief are at the mercy of their origins, ebbing and flowing with the interest of their creators; many will wane as trends move on or fade away completely once forgotten.

The "imaginary" element comprising the Universe, from which all Sourcery draws power and from which Alkahest (and by extension Azoth) is made. Summarily, the Source is the abstract "waters" of the Cosmic Ocean. Shares a name with one of the Sourcestar's many epithets; also called magic (alongside Sourcery).

The transitory stage between an Oort burning out and the formation of a Boötes. Resembles the head of a dandelion flower; hyaline, opalescent, and aglow with latent energy much like a Sourcefeather.

For every universe, there is an equal and opposite universe to match it. Each pair is woven around by Ouroboros in a lemniscate shape (∞), and the center of this shape is the Sourcecore.

The Sourcecore is where the Ouroboros Husk infinitely consumes its own tail, as well as the "formal" Sourcegate between universes. The Universe where Ouroboros's head is facing it is referred to as the Head Universe, and for the tail side, the Tail Universe. 

Starlyngs may make a "rite of passage" pilgrimage (the Quest of the Querent) to the Sourcecore/Sourcegate to pose the Husk their one allotted question, which Ouroboros had "programmed" itself to answer before its consciousness departed. The specific location of where this question is posed is called the Nexus.

Detritus from the decay of the Sourcering; a hyaline and opalescent feather aglow with latent energy. May or may not develop into an Oort. 

Entrances between each universe via weakened points in the Sourcering or, more formally, at the Sourcecore (via the Head or Tail of the Ouroboros Husk).  

The "official" Sourcegate cannot be passed through without specific criteria being met, such as a Firstborn or Reaper (both can pass freely) escort; it naturally rejects foreign entrants, unlike weakened areas in the Sourcering membrane. Sustainers will reinforce problematic Sourcegates using Azoth. 

Starlyngs may make a "rite of passage" pilgrimage (the Quest of the Querent) to the Sourcecore/Sourcegate to pose the Husk their one allotted question, which Ouroboros had "programmed" itself to answer before its consciousness departed. The specific location of where this question is posed is called the Nexus.

The length of Ouroboros's body that forms the perimeter of (and thus the boundary between) every universe. May also be called the Boundary or Edge, among many other names.

Also known as the Universal Magic or just magic, Sourcery (sorcery) is the study of the Universe, Ouroboros, and Omnicosm. Though it shares its definition with Allchemy, Sourcery revolves around what is "nonphysical" or otherwise remote from "reality" (in essence, it's magic; anything involving "unreality" can be called Sourcery), whereas Allchemy does not. The energy all Sourcery is derived from is called the Source, which shares its name with the Sourcestar.

Be it naturally or learned, those that can wield Sourcery are called Sourcerers (name shared with the All is One rank, Citrinitas).

Another (and the most commonly used) name for Ouroboros.
