Allison's Atum crown
"An Atum that burns particularly bright can actually be seen as an aura or ring of light, sometimes called a halo or animus. In those warriors or sages that have cultivated enough strength, it burns as a physical, smokeless flame across their body. The sage-kings of the First Conquest were said to have golden animus that wreathed their body in flames as bright and hot as molten metal, while leaving their skin and clothing unharmed. YISUN was said to have an aura which is called The Song of Maybe. According to legend, it burned at seven hundred million degrees, and when YISUN let it burn, it was so wide that it turned the tips of the branches of the trees that hold up the corners of creation to ash."
The Atum is the refined soul flame or essence of each individual, as opposed to the Great Flames of the Gods and the Flame Immortal of the eternal God YISUN. Many believe that the separation between the Atum, or individual soul, and the oversoul of the Flame Immortal is fundamentally illusory - that they are one and the same.[1b]
The Atum is observed by modern medicine in Throne to flow through many channels, or meridians, within the body. Precise knowledge of how the soul flame flows through these channels, the ways in which it can become blocked (such as with Vacus Needles[4]), and the ways it can be aligned to unlock a person's hidden potential are key to various schools of martial arts throughout the multiverse.[1b]
Breath is key in controlling one's Atum. Someone with high breath control not only has incredible constitution and body health, but has also aligned the energy pathways in their body to the point that they can perform unbelievable physical feats of endurance, such as turning blades away from their skin.[1a]
Animals have their own Atum, but it is so weak that they disperse immediately upon entering the Void.[2]
