Wintrium
this glass-like substance remains in liquid form at very low temperatures, and can take as much as 10,000 years to solidify under normal conditions. It is found in the Derelkoos Desert of Klatooine, where it seeps from the desert and creates incredibly beautiful, natural sculptures. The Klatooinans call the landmark the Fountain of the Ancients, and revere it for its tenacious and wonderful existence.
