During the era of the Clone Wars, specifically within the time frame of those events, a clandestine laboratory was maintained by the Believers Sith cult. This lab was situated within the S-Ipsus manufacturing station, which itself was located on the planet known as Genarius. Around 21 BBY, these cult members initiated a scheme aimed at the total annihilation of the Caarite species. To achieve this, they perfected an anti-Caarite virus inside their secret laboratory. Following this, multiple tanks containing the virus were dispatched from the facility on three separate transports. However, soon after these transports left carrying their lethal payload, the Metatheran Cartel, a trade group managed by Caarites, dispatched a strike force that then conducted a raid on the laboratory.
