Varik, Danison, a Corellian male Chagrian, served as the principal scientist for the Sith Empire throughout the Galactic War.
Varik commenced the production of experimental droids within a fortified installation in 3640 BBY, intending to deploy them in support of the Empire's conquest of Corellia. Upon the Republic's successful breach of the vault doors, designed to function as a prison, Varik initiated his droids' programming to terminate the intruders. Subsequent to the neutralization of his droids, Varik admitted his collaborationist activities and was subsequently apprehended.
