The Terranids are an extremely invasive, bug-like species known for their ability to infect and devastate worlds. Highly adaptable, they can develop new sizes, forms, abilities, and functionalities within a generation or two based on their environment and challenges. Their ecosystem is complex, with smaller species evolving to manage their micro-biomes, some adapting as workers and breeders, while others become combat specialists.

Terranids have large forms referred to by those in the Arcanex Galaxy as “Catapults” that use a chemically-produced substance to launch colonies of eggs into space. These eggs float aimlessly until they land on a planet with ample organic material. With a short and highly productive lifecycle of about six months, Terranids rapidly consume organic materials, breed, and expand. Outbreaks can quickly spiral out of control due to their extremely high birth rates and adaptive capabilities.

Terranids come in a multitude of forms but are identifiable by their distinct yellow glow, caused by the caustic chemicals and acids they produce for both their Catapults and combat. This makes them not only dangerous but also extremely caustic.
