The Iokath system, found within the Unknown Regions of the galaxy, was a star system. Prior to the conclusion of the Manderon period, a foreign species selected this system as the site for the implementation of Project Iokath. To construct an enormous self-sustaining ecosphere that would entirely encompass its star and utilize all of its energy, every single celestial body within the system, including all asteroids, was dismantled and its components were repurposed. This massive habitat was given the name Iokath, and because it prevented any light from escaping the star after completion, the entire system became impossible for the rest of the galaxy to detect.
Star Wars: The Old Republic: Knights of the Eternal Throne features the Iokath system. Iokath can be described as a fictional construct known as a Dyson sphere, although this specific term is not explicitly mentioned within Star Wars.
