Sith observatory

A Sith observatory was constructed on a large asteroid in the Hebine Ring, an asteroid belt in the Beheboth system of the Outer Rim Territories' Sanbra sector. Built long before 3643 BBY by members of the Sith tradition of Force-users, the observatory contained a cache of star charts and made the Hebine Ring in general an important location to the Sith. The Hebine Ring's significance eventually came to be suggested by the designs in a certain relic.

Around 3643 BBY, an individual affiliated with one of the sides in the ongoing struggle between the Galactic Republic and the reconstituted Sith Empire discerned that the relic pointed to the Hebine Ring and subsequently dispatched a companion to investigate the asteroid belt. The companion then discovered the observatory's remains and found the cache of star charts to be still intact.
