In the world of Siravia, Gremlins are one of the more common races on the planet. Physically, Gremlins are reptilian creatures with skinny (almost anorexic) bodies, four long skinny arms ending in three clawed hands, digi-grade feet with three adhesive toes allowing them to climb walls, a long, prehensil tail, and large ears. The coloring of the Gremlins varies greater than any other specie on the planet. Ranging from blue, green, yellow, pink, purple, etc.

Gremlins are heavily industrialized, and have a sixth-sense about technology. Aside from the Technites and Mechanites, Gremlins are the most technologically advanced species on the planet. The bulk of the species lives on the island of Cumulopia, a massive, flying, mechanical island, built by the Gremlins after the Technites overan their original home island. Gremlins are noteworthy for the creation of air flight (specifically Air Ships) and their services are in high demand as Air Ship mechanics.

Demonic Gremlins bear a stronger resemblance to their namesake, in both appearance and nature. They usually have a coloration of either swamp green, black, or gray, with sharpened teeth boney ridges covering their bodies and have an obsession with dismantling every piece of machinery they see.
