Astrouine was a desert planet in the Outer Rim territories. It was located in the little known Delanni sector, which neighbored the Minos Cluster and Elrood sector. Nearly two millennia before its latest discovery, a Sith Master and his apprentice had fled an internal Sith conflict on Korriban, and fled to Astrouine, there they formed their own small community of warrior people known as the Antiri. Much later, the ruins of the Antiri temple were found by Darth Lucid when he arrived with his master, Arden Shan. Darth Vader attacked and killed Shan, taking on Darth Lucid as his secret apprentice.
