Energon, Xag-Ya

DESCRIPTION: The xag-ya is a floating, silver-white globe veined with dozens of writhing filament tentacles of living light, its surface shimmering like quicksilver beneath a soft, warm halo. Their surface ripples with quicksilver sheens and transient bright ocelli that track motion. Up close, it’s bright enough to cast crisp shadows and reveal dust motes in the air, and it smells of ozone and warm rain. Touching a xag-ya feels like an uncontrolled surge of vital power—pins-and-needles behind the eyes, a fullness in the lungs, and a giddy pressure that threatens to spill over into painful overcharge, nosebleed or migraine if it continues too long. When a xag-ya materialises, the air around it hums at a barely audible high pitch, colours saturate, and plants begin to writhe blossom if brought too near.

PREFERRED HABITAT: The xag-ya prefers the blazing immensity of the Positive Energy Plane, drifting through pockets of calm brilliance where it stirs up eddies in the undifferentiated life-forces. Beyond its glowing home, the xag-ya frequents bright borders and quasi-elemental extensions like the planes of Lightning, Radiance, or along the Deep Ethereal where the tides of positive energy lap at colour pools. When met off-plane, a xag-ya is typically surveying loci of growth—verdant demiplanes, sun-kissed reefs, colourful jungles—or acting as a guide across hazardous positive gradients for planewalkers who somehow earn its trust.

PHILOSOPHY / SOCIETY: Xag-ya are thought to be solitary because their presence overstimulates environments, accidentally igniting or overcharging nearby matter and life, making sustainable communities impractical even with their own kind. Their temperament is curious and restrained: xag-ya prefer to observe, to sample phenomena of flourishing, birth, and renewal, and to practice fine control so they can learn how to heals or empower with their touch rather than harm, when possible. Philosophically, they seem to ensure that energy should flow to where it is needed to sustain life without excess. To a mature xag-ya, it appears indiscriminate growth is as wasteful as ruin.

ECOLOGY: It’s thought that xag-ya to feed upon the energy flux of the planes—the mere presence of living material infuses them with a sparkling radiance, without harming the source. Xag-ya have never been known to reproduce, in fact, they don’t even seem to interact with one another. Vitality energons of different sizes have been encountered, so graybeards believe they do age and grow, and presumably reproduce asexually.

Xag-ya and xeg-yi are opposite aspects of planar energy; if two should ever they meet, they rush together and annihilate in an amplified explosion. It’s a phenomenon that daring planewalkers have exploited as a dangerous, last-resort planar flare or as a ritual reset to cleanse cursed areas.

COMBAT: In combat, a xag-ya will striking with its tendrils or lancing positive-energy rays at a range. Either of these attacks actually heal their targets rather than harm them, which may seem counter-intuitive. However, the xag-ya does not stop when a target is at full health—it can continue to overload them with more and more energy. While this initially feels exhilarating [and manifests as bonus hit points], it rapidly becomes painful, dangerous and even deadly [if a target reaches double its maximum hot point total, it spontaneously combusts and dies]. It sets combustible objects alight, and heats metals. Conversely, the vitality energy of a xag-ya causes severe damage to most kinds of undead.

Xag-ya use their incorporeality to gain a tactical advantage, ducking into walls and ceilings. They leave scorch marks on solid objects when they do this, making tracking easier. Magical weapons are required to damage a xag-ya.

Upon destruction, a xag-ya detonates in a concussive surge of radiance that can also injure or fatally overcharge living targets, ignite flammables, and heat metal as if struck by a concentrated wave of sunlight.
