Phobium Phobium is a heavy metallic alloy that was created using chanlon ore. This ore is naturally found on the planets Gargon and Dor.
Its initial discovery occurred several millennia prior to the Galactic Civil War, and it was intended for usage in power cells. Occasionally, Jedi Knights used phobium in their lightsabers, specifically in the power cells and emitters. During the Galactic War, which was fought between the Galactic Republic and the Sith Empire, phobium was utilized in the construction of heavy armor plating.
In the Galactic Civil War's initial stages, Emperor Palpatine deployed mining teams to Gargon to extract the element. The ore from Dor underwent processing and was combined with doonium compounds. This mixture was subsequently employed as a coating for the power core of the second Death Star.
