The Dinares Sector is a desolate region of space in the Milky Way. It was the home of the roving mantis screamers before they were assimilated into the Zerg Swarm and turned into the terrifying mutalisks. These creatures once built their towering nests (which became the basis of the zerg spire) on the lifeless worlds of the sector.
