The Krayiss Two system, alternatively referred to as the Krayiss system, existed as a stellar system situated within the Outer Rim's region of Sith Worlds, and its primary celestial body was the planet Krayiss II.
The initial mention of the Krayiss Two system appeared in Tales of the Jedi Companion, with a subsequent reference in The Essential Atlas, a reference book from 2009 authored by Jason Fry and Daniel Wallace. Despite the system's placement in grid square R-4 on a map of Sith Worlds featured in The Essential Atlas, the book's Appendix section indicated its location as square R-5, a detail reiterated in the Online Companion update to StarWars.com in 2015. This article operates under the assumption that the visual map's placement is incorrect, and that R-5 represents the system's true grid square.
