The Coyerti species represented just one of the many indigenous life forms populating the planet known as Coyerti.
The Coyerti demonstrated a remarkable resilience against the Imperial forces occupying their homeworld, withstanding the superior power for a considerable time period. Nevertheless, their intricate biological makeup introduced a significant vulnerability during their reproductive cycle, a weakness that the Imperials were quick to take advantage of. Anticipating this, the Rebel Alliance's high command received a distress call, resulting in the deployment of the Alliance's 61st Mobile Infantry. This unit, also referred to as Twilight Company, successfully eliminated the Imperial biotoxin production sites and safeguarded the Coyerti throughout their vulnerable reproductive phase.
The Coyerti species made its debut in the 2015 book Battlefront: Twilight Company, penned by Alexander Freed.
