Removed: No Longer Available
Impervium Compound was removed from the game files, and is no longer obtainable.
The crafting schematic for Impervium Compound was learned automatically after picking up Refined Violium. After picking up Impervium Compound for the first time, players would automatically learn the crafting schematics for Impervium Chair, Impervium Door, Impervium Light, Impervium Console, Impervium Bed, and Impervium Table.
Impervium, in the real world, was created by the late inventor Walter Gutierrez, and its trademark and manufacturing rights currently belong to his heirs. The real life Impervium and its sister product Impervicon are in fact compounds made of a fiber stronger that concrete and wood useful for a variety of applications like those mentioned in this game, though Mr. Gutierrez was convicted in Los Angeles in 1986, along with business associates Michael & Peggy DuPont, on tax evasion and other charges in connection with the misrepresentation of the product. Starbound's infringement of the trademark was not litigated because the family loves the game.
