Voidwalkers are a strange species, as intelligent as any other sapient life and yet utterly disinterested in formal communication. From what researchers are able to glean from their limited interactions, Voidwalkers are not native to Chroma at all, despite how well they have adapted to the environment—it seems they are able to quickly travel long distances via use of self-created portals. These portals can be created at will, but the Voidwalker passively creates them beneath and behind their paws when agitated or mobile. Though they can communicate verbally after learning the target language, they favour their natural, emotion-based telepathy. A Voidwalker's face is inexpressive, but its fins display clear emotion. Males carry dark black striping on these fins, thought to be intended to make them appear torn, as if he has participated in and survived many battles.
Though clever and capable of rational thinking, Voidwalkers are inquisitive to the point of putting themselves in danger in order to investigate something they are unfamiliar with—even disturbing obvious predators in their quest to do so. However, prolonged research has shown that the Voidwalker is more than capable of escaping an irate animal; they are incredibly fast runners, strong swimmers, and flexible escape artists. Indeed, though they are clearly well-adapted for terrestrial environments, their general builds and excess of fins suggest that Voidwalkers evolved in a coastal environment—thriving in and near the water, even though they can survive just about anywhere. It is thought that they were even originally abyssal animals, with glowing neon-bright markings serving to light their surroundings and attract prey. Even their scales are glossy and fishlike, proving water-tight and slippery when wet. They are exclusively predatory animals, favouring birds and fish.
