Schematic. Ren is invisible, so this is a diagram and not a view of anything a person sees.

Ren Signature

A Signature is a person's unique Ren 'fingerprint'. This fingerprint changes with the person, but no two are exactly alike. Few are able to read them distinctly, rather than just grasp the polarities from them.

Signatures are composed of a person's polarities, with the polarity related to their motive occupying a core spot, and the object of their motive determining the structure. As a Character progresses in Realm and wielding Ren, the signature advances.

Realm 0

Void

A Character in this Realm is establishing their polarities. They're loosely connected, only bounded by texture. These polarities aren't even felt, much less controllable.

Realm 1

Spark

A Character in this Realm awoke to Ren, and gained Awareness, by which they sense and move their Ren. They are learning how to have their polarities interact and circulate Ren. They establish connections and the interactions (circulation) between their polarities to move to the next Realm.

Realm 2

Flame

A Character in this Realm has established their circulation, and is learning how to centralize their Ren into a more stabilized form called a centralization, adjusting the external interactions with how they gather Ren and consume it to fuel themselves. Once they do, they move into the next Realm.

Realm 3

Star

A Character in this Realm has centralized their Ren, and is learning how to Realize their signature at a larger scale, further increasing the density and flexibility of their Awareness.

Realm 4

Constellation

A Character in this Realm has Realized their signature, and is learning how to expand their signature into a galaxy to further fixate themselves as part of the world and strengthen their Awareness.

Realm 5

Galaxy

A Character at this Realm has no higher to go, unless they uniquely qualify to become a spirit.
