The Swarm War saw the Thyferra coup transpire in 36 ABY, an event where Killiks in conjunction with black membrosia-dependent Vratix forcibly gained power on the planet of Thyferra. This takeover allowed them to commandeer the galaxy's bacta reserves. Corran Horn, a Jedi Master, was sent with a squad of Jedi Knights to thwart the coup, yet a miscommunication led to Gilad Pellaeon's forces delaying them, preventing their intervention in the Killiks' successful power grab.
