The Venom Guard represented a highly skilled and specialized group operating as part of the Imperial Navy's special forces.
After Moff Sakai of the Thuris sector learned the identities of Rebel operatives who were attempting to undermine his authority, he reached out to the Venom Guard. This military unit, belonging to the Imperial Special Forces branch of the Imperial Naval Special Forces, subsequently initiated a pursuit of these Rebels, specifically the members of the distinguished unit known as Reekeene's Roughnecks.
