Shaderon was a planet in the Unknown Regions. After the Great Territorial War, former Jedi Grandmaster Damien Nightblade settled on Shaderon. Ussej Padric Bac considered the planet to be Nightblade's rightful place. However, Bac believed that Shaderon somehow twisted Nightblade's mind. The former Grandmaster later fell to the dark side of the Force and became Darth Plagueis.
