When the Empire came to power, the Jedi Temple was scoured of its inhabitants; the Jedi were routed and exterminated by Darth Vader and his ruthless 501st legion of clone troopers. Once the Temple was pacified, Palpatine raided its vast archives, stealing away with a horde of precious Jedi lore which he stored in secret repositories on such worlds as Wayland and Byss. The Jedi Temple still stood during his regime, but it was an empty husk of its former glory and a stark reminder of the consequences of rebellion against the Empire.
