The Subterra Period was a period of time in the galaxy that lasted from 8000 BBY to 7000 BBY. During this time, there was new mapping of the galactic southern quadrant. The planet of Malastare acted as an anchor for short hyperlane snippets, also known as praediums. The supply lines that linked the galaxy with the Rishi Maze were also constructed.[5]

The rapid expansion however led to lawlessness in the Rim and Coruscant lost its control on its new territories. This was thought to have contributed to the Second Great Schism in 7003 BBY, which led to the start of the Hundred-Year Darkness.
