In the Galactic Standard Calendar, the standard year designated as 6100 BBY, which is short for 6100 Before the Battle of Yavin, occurred during the Manderon Period. The planet Saleucami, situated within the Outer Rim Territories, had already undergone colonization by this time (6100 BBY) due to its pleasant climate and significant geothermal activity.
The year 6100 BBY was initially established for inclusion in The Essential Atlas, a book authored by Daniel Wallace and Jason Fry and published in 2009.
