A jumbled collection of lazily floating asteroids, Polis Massa is a small Outer Rim mining settlement far removed from the more populated areas of the galaxy. The airless rocks are host to sealed outposts inhabited by the strangely silent
Polis Massan aliens.
It was at one of these outposts that Jedi fugitives Yoda and Obi-Wan Kenobi regrouped following the disastrous decimation of their order by the rise of Empire. Having failed to thwart Palpatine, Yoda fled to Polis Massa with Bail Organa to recover. Obi-Wan Kenobi, having defeated Darth Vader on Mustafar, soon joined them.
He arrived on Polis Massa aboard Padmé Amidala's Naboo star skiff, and carried an ailing Amidala aboard. The Jedi rushed Amidala to the medical center, where the Polis Massan medics and droids tried to stabilize her vital signs.
Padmé died on Polis Massa, but not before delivering the twins she was carrying. She gave birth to Luke and Leia, infants that carried with them the hope for the future.
