The First Sun
Aza is the largest of the two suns and glows a bright yellow-white. Aza is so bright that its sister sun, Sao, is almost impossible to see when it gets close to Aza.
Aza produces the strongest wavelength of hot Aura. Its strength only drops during eclipses. Aza cannot be completely blocked by Sao during an eclipse, so the only time its Aura is completely inaccessible is at night.
Because of its near-constant Aura output, Luminous lifeforms of Aza's Luminosity are at the greatest risk of combustion. Combustion from Aza-aligned species are also the most violent.
