Bandorium
this unusual, liquid metal was found in the oceans of the planet Bandomeer, specifically long the path of the Gray Westerly. Scientists and engineers working for the major mining operations on Bandomeer discovered that bandorium seemed to move about in "tides," which seemed to be controlled by the winds of the Gray Westerly. The exact nature of these tides was not discovered. Bandorium was used in many starship counter-sensor systems, and it was believed that it was also used in the creation of cloaking devices.
