Glessene sector

From Memory Alpha, the free Star Trek reference

The Glessene sector is a region of space in the Milky Way Galaxy.

Deep Space 9's navigational computer held maps for this region of space. In 2369, on stardate 46423, Kira Nerys tried to access maps of the Argosian sector but due to technical malfunctions, Glessene sector maps were retrieved instead. (DS9: "Babel")
