Caphexdis, a planet that calls the Mid Rim Territories and the New Territories home, existed as a celestial body. It was found at coordinates M-7 on the Standard Galactic Grid, and served as the original homeworld for the Caphex Resistance spy known as Seossra Thwisp. This piece of information appeared on a bounty that was put out for Thwisp during the First Order's occupation of the planet Batuu around the time of 34 ABY.
The reference book Star Wars: The Rise of Skywalker: The Visual Dictionary, penned by Pablo Hidalgo and released in 2019, marked the initial appearance of Caphexdis.
