Dead Sector

Dead Sectors were areas of the planet Coruscant that had been removed from the power grid.

In the year 722 BBY, the Dacho District was the site of a catastrophic industrial accident that resulted in the deaths of 300,000 trapped workers. As many of the bodies were sealed behind collapsed sections and considered unrecoverable, the district held the unpleasant distinction of being the galaxy's largest tomb and became the most infamous of Coruscant's Dead Sectors.
