A strange power known as Celestial Aura radiates from celestial bodies, such as stars, moons, and planets. This Aura has many properties, and differs in nature depending on the type of body it originates from.
Luminous materials are elements and compounds that are especially reactive to Aura. These materials saturate the planet in many states, even existing within the biology of several of its lifeforms. These lifeforms (known as Glowfauna (category link) and Glowflora (category link)) are able to harness Celestial Aura for themselves in the form of Glow.
Luminous materials and Aura interact to create phenomena unique to SanZera and its creatures. The stability of the planet depends on their existence.
