Primeval Lux, the embodiment of the first light to pierce the void of creation, exists as a concept more than a being. With no discernible age, Lux appears as a radiant figure, an amalgamation of light that shifts and pulses with the essence of creation itself. Their form, if it can be called that, is a dazzling display of luminescence, with no fixed shape but rather a flowing, ever-changing mass of brilliance. Lux's presence is felt rather than seen, a warmth and clarity that permeates the air around them, casting no shadow, for they are the source of all illumination.

Lux's desire is as ancient as they are: to maintain the purity and sanctity of light across the cosmos. They wish to see every corner of existence bathed in the clarity and truth that only light can bring. However, the universe is vast and filled with shadows and darkness that resist Lux's efforts. These forces of obscurity, born from the same primordial chaos as Lux, challenge their dominion and dilute the purity of light.

In response, Lux does not battle directly but rather seeks to inspire and guide those who can carry their light into the darkest corners. They appear to mortals and immortals alike, often as a guiding star or a sudden burst of insight, urging them to spread light in their own way. This method works because Lux understands that light, like knowledge, spreads best through the actions and beliefs of others.

Yet, the struggle is endless. As Lux's light reaches further, so too do the shadows grow, reacting and adapting. The conflict in Lux's existence is the eternal dance between light and darkness, a balance that must be maintained yet constantly shifts. Lux's journey is one of perseverance, a testament to the enduring nature of light against the encroaching void.

Primeval Lux's unique trait is their voice, which sounds like the harmonious resonance of a thousand chimes, echoing with the purity of the first dawn. This voice, heard only by those Lux chooses to guide, carries the weight of creation itself, inspiring awe and action in equal measure.
