Physical Description[edit]

A Nova and Shade Callisto. Art by Astromore

The callisto are beings that glow pure liquefied stardust akin to the stars. They can vary in color, shade callisto taking on the look of the night's sky, while nova look like vibrant glowsticks in the shape of a person. Most glow one or two colors. Their constellations are given form at birth though new constellations appear as they age and discover new things in their lives. Their faces opaque and obscured enough by either light or shadow to only be able to just make out their facial features. As such callisto that share the same hue are hard to tell apart given that they share the same haircut. As they grow older the color becomes more unsaturated and less saturated with the exception of white Callisto. While hardly seen due to either how bright or dark their likeness tends to be, the callisto do have facial features like that of a human. The expressions they make largely consist of white constillation-esk symbols just below their skin slowly twinkling and shimmering much like the nights sky. An intense glow or vibration indicate moods. When expressing intense emotion their hair tends to linger as they move from one place to the next leaving streams of their visage where they just were. They're humanoid and stand at roughly the same remote height as humans. They consist of a flesh-like translucent skin that contains a glow stick like substance that acts as their blood. It appears to be the same hue as the callisto, be it the nights sky seeping from their wound, or a neon trail; It falls upward into the sky. Immediately evaporating the moment it leaves their body. Akin to bloodloss if too much of it is lost their core will destabilize and they will die. The body drained of their neon blood is left a darkened lifeless color of what it once was. Akin to a heartbeat, a deceased callisto no longer vibrates. They are held together by the pure celestial energy held within their cores. Warm to the touch like humans, they constantly emit a soft vibration that can be felt if one places their hand upon them. The callisto have only one organ that keeps their energy in held together. The core in their chest. It is considered their most vital and only organ. While other attacks such as decapitation only leave them victim to mass bloodloss akin to losing a leg. if their core sustains any slight damage they may instantly die. The core acts as their brain, heart and all other organs combined in one. Roughly the size of a human heart the Core resembles a crystal cluster the same hue as the callisto. Shade callisto have a core the neon color as they were when they were born despite looking like the nights sky.


It was once said the gods were at war. The resulting conflict gave way to whole stars exploding and sending their contents across the universe. After the war in an attempt to fix the damage done, the gods tried to repair those broken stars they left in their wake. And the resulting residual energy was left in the Astral plane. And with the gods powers of rejuvenation, that left behind energy; in hundreds of thousands of pieces, gained a will of its own. And thus the callisto were born. Finding one another, and venturing to the mortal plane cluster by cluster in order to venture and sate their wanderlust.

A common story told by the elders.


Callisto are ever curious, wanting to find out why they were born and the bounds and ends to the world around them. Not really concerning themselves with long-standing conflicts, they prefer to explore to answer questions to solve those conflicts before they even come to a climax. They study their angelic properties to uncover who the deity was that brought them their corporeal form. Exploration driving them the most. Almost every callisto one would meet has, or is in progress of traveling around the world. They can't stand being in one place too long leading to a very nomadic lifestyle. Clusters of callisto usually consist of a few key members leading the group with 2/3rd's of them leaving and returning frequently. They gather all the good things they've learned from other races and apply them in their cities and homes. Making them as a whole more diplomatic and easy to approach than some of the more aggressive races. They value wisdom and knowledge the most.


Callisto are at a glance most akin to A modern glow stick. Their skin warm to the touch vibrates slightly as the arcane stardust swirls inside them. When they're harmed their Stardust comes out a glowing liquid form not taking long for it to evaporate erasing any trace of it in the process. As they sustain more damage their glow becomes less and less bright until they dim out losing all hue and luminescence. Their corpse a grey colorless husk no longer vibrating or swirling with arcane energy. with their inside looking darker as their body is observed closer to their core. A callisto with their core removed instantly dies, akin to ripping out one's heart. Not long after their blood evaporates and their skin hardens to a texture akin to Glass. Brittle and easily broken. The callisto Core, a Gem like formation lying in the center of their chest with colors matching the specific glow of the individual callisto. These cores act as their hearts. A primary organ pumping Arcane energy throughout the callisto. Due to the Cores arcane nature they are highly coveted by those interested in the arcane. Being used as arcane foci and spell components. All of which are held in contempt by the callisto themselves.
