On Dark and Light

[Ardox]

The main misinterpretation is that Umbral/Astral as something to do with Light/Dark

It's 2 differents axes.
Umbral/Astral roughly translate to passive and active.

By example: Astral Fire manifest as flames and Umbral Fire manifest as dryness.
Wind, Lightning and Fire are tiped toward Astral and Earth, Ice Water are tiped towards Umbral

No elements are (as far as we know) typed toward Light or Dark..

As the nature of Light and Dark, we don't have a extensive cannon explaination yet.. They are not elements (even if they have elemental sprites).

Light can be Umbral or Astral, Darkness can be Umbral or Astral.


Thancred remark about having it mixed up is related to the fact that each interpretation focus on different aspect of those energies

From what I understood:
Astral Light: Prosperity & Growth
Umbral Light: Serenity and statis
Astral Darkness: Diversity, Creativity
Umbral Darkness: Chaos and Decay

The last part is absolutely non cannon, but I putted it there to illustrate the nuances between those 2 axes..
