Polis Massa

Polis Massa is a large asteroid, within an asteroid field of the same name, in the Subterrel sector of the Outer Rim Territories. Once a planet, the asteroid field is all that remains following a mysterious cataclysm which occurred in around 500 BBY. Polis Massa is far from major hyperspace routes and is isolated from the rest of the inhabited galaxy, though there is an archaeological base on the asteroid.

In 19 BBY, Bail Organa organized the refuge of several Jedi survivors of the Great Jedi Purge at Polis Massa. One of these Jedi survivors was likely Grand Master Yoda.

Later in 19 BBY, Newt Liryas and Thomas Verdi arrived at Polis Massa after being directed there by Mon Mothma. Senator Organa was able to answer many of Newt's questions about the Great Purge, but refused to answer his questions about potential survivors, though he did confirm there were other survivors. Newt could feel the lingering effects of Yoda having been in the base, but could not identify any potential others.
