Polysteel, a material utilized in the creation of statues, was once used to fabricate a likeness of the Tionese Despot Xim. This statue, manufactured in a factory located on the planet Centares, showcased Xim brandishing a heatbeam. The statue was then displayed within an arena situated on the world of Soruus. The historian Bleys Harand made reference to the polysteel statue within his work, Travels Amid Strange Stars, where he deemed it an inaccurate representation of Xim.
The initial mention of polysteel occurred in 2013 within the third entry of Star Wars: The Essential Guide to Warfare Author's Cut. This series of posts on the StarWars.com blog presented content omitted from The Essential Guide to Warfare. Jason Fry and Paul R. Urquhart authored the post, which provided no specific details regarding the era in which polysteel was employed.
