Lumen is a being of pure Light energy, formed when a collapsing starbeam pierced the upper skies of the Light Kingdom and crystallized into a conscious entity. At first it existed only as a drifting glow, silently hovering above temples and battlefields alike, but over time it learned to shape itself into a figure that mortals could understand. Lumen does not speak; instead, it communicates through pulses of warmth and radiant flashes that calm fear and push back darkness. Wherever corruption spreads or shadow creatures gather, Lumen appears without warning, bathing the land in a gentle brilliance that weakens evil and strengthens allies. Yet its presence is not endless — each time it releases its full radiance, a portion of its essence fades, meaning this guardian sacrifices a piece of its own light every time it saves the world.
