MUTARA SECTOR AND ITS NEBULA

The Mutara Sector is the location where the S.S. Botany Bay was discovered adrift in 2267. Is also the location of the Genesis Planet and the Regula I planetoid.
The Mutara Nebula is an intersellar dust cloud in the Mutara Sector, where Khan detonated the experimental Genesis torpedo in 2285, causing the Mutara Nebula to re-form into a habitable planet. The nebula was composed of ionized gas that made a starship's sensor highly unreliable when inside.
