Wintrium was a fluid substance that emerged from the Fountain of Ancients, situated within the Derelkoos Desert on the planet Klatooine. Upon contact with the arid atmosphere of the desert, it underwent a transformation, solidifying into a substance resembling glass, seemingly suspended in time. The hardness of wintrium increased with age, eventually reaching a state of near-indestructibility over extended periods. In the course of the Starstalker's task of acquiring wintrium from the Fountain, the Sith Sabers named Anyul and Marjaak employed their lightsabers to extract wintrium from the sculpted formation, an endeavor that proved exceedingly difficult even with the aid of their lightsabers. The pak'pah fruit, unique to Klatooine, was believed by numerous researchers to owe its existence to the wintrium present within the world's ground.
