Yavin system/Legends

The Yavin system was a three-planet star system in the Outer Rim Territories that contained the gas giant Yavin Prime and its twenty-six moons; three of which were habitable: Yavin 4, Yavin 8, and Yavin 13.

Description
The Yavin system consisted of a medium-sized orange star with three worlds orbiting it. The closest to the sun, Fiddanl, was a barren planet covered with mercury seas and instable landmasses. The second orbit was occupied by Stroiketcy, a captured comet, and the last planet in the system was Yavin Prime, a red gas giant.

History
The Yavin system was discovered during the Expansionist Era of the Galactic Republic. As was customary at the time, the name Yavin was given to both the star and the major world in the system. The first exploration report deemed the system unfit for Human colonization and probably devoid of any lifeform, let alone intelligent life. Upon entering the system, the early scouts noticed an orange sun nearing the term of its middle-age cycle. The explorers thought they needed look no further, so they left the system after a brief cursory examination of the planets and moons.

The Yavin system remained a brief footnote in the planetary registries of the Republic for centuries, but Yavin 4 became a Sith stronghold around 5,000 BBY, when the Sith Lord Naga Sadow went into self-imposed exile following his defeat at the Second Battle of Korriban.

However, the Yavin system remained largely unknown and uncharted until millennia later, when the Alliance to Restore the Republic set up a major base in the fourth moon of Yavin Prime.
