The Quarantine Zone was a region on the planet Dathomir that was quarantined by the Galactic Empire in about 1 ABY, following an outbreak of the blackwing virus. The virus killed most of the people inside the Zone and turned them into zombies. The survivors established five camps inside the Zone, Camp Alpha, Camp Beta, Camp Gamma, Camp Delta and Camp Epsilon, to live in safety. However, the camps all came under regular attack from the zombies.
