Cassandran Worlds

The Cassandran Worlds was a planet and the homeworld of the Jedi Master Sifo-Dyas, a human male.

Behind the scenes
The Cassandran Worlds were originally introduced for the Star Wars Legends brand in 2004, first seen in the Star Wars Roleplaying Game sourcebook Geonosis and the Outer Rim Worlds as a loose-alliance of multiple planets. In the new Star Wars canon, however, the Cassandran Worlds have only been mentioned by name in the 2015 sourcebook, Ultimate Star Wars, as the homeworld of Sifo-Dyas. The 2012 reference book The Essential Guide to Warfare, another Legends sourcebook, also established the Cassandran Worlds as the Jedi Master's homeworld.
