Ondos, a planet, existed in the distant past. Its location was within the Core Worlds region. Together with Had Abbadon, it was among the few worlds considered as a possible origin point for either the Jedi Order or the earlier users of the Force.
The initial screenplay, specifically the second draft for A New Hope, ended by indicating that the offspring of Starkiller would embark on a perilous journey to find the "Princess of Ondos."
