The Imperial forces stationed at Coyerti had the responsibility of safeguarding the biotoxin assets under the control of the Empire. This responsibility was challenged in 3 ABY when the Rebel Alliance's 61st Mobile Infantry launched an invasion as part of the Mid Rim Retreat. During the ensuing planetary conflict, the 61st achieved victory, successfully obliterating the biotoxin production sites and protecting the indigenous Coyerti species.
The Coyerti garrison was initially featured in the 2015 canon novel titled Battlefront: Twilight Company, which was penned by Alexander Freed.
