Maryo, a vacation destination situated in the Corporate Sector, was a resort world. The planet was famous for its marketplaces, attracting affluent individuals seeking leisure. Furthermore, visitors to the world took pleasure in activities such as hunting the indigenous peckvas and angling for colossal fish in its expansive oceans.
Following the passing of Torm and Trevim's mother, Dixon, Torm, and Trevim Dadeferron journeyed to this planet. It was on Maryo that the Corporate Sector Authority enlisted Torm to act as a spy observing Dixon and Trevim.
N'zaet Nir also resided on Maryo.
The initial reference to Maryo occurred within Han Solo and the Corporate Sector Sourcebook. Subsequently, it appeared in an entry of the Star Wars Encyclopedia, but with the alternate spelling "Mayro." This particular spelling of the planet's designation persisted in both A Guide to the Star Wars Universe, Third Edition, Revised and Expanded and the short narrative "Omega Squad: Targets." The original spelling, "Maryo," was then reinstated in both The Complete Star Wars Encyclopedia and The Essential Atlas.
