Termadus was the white dwarf companion to the main sequence star Morasil in the Cularin system. Termadus was a much younger star than its counterpart. A gaseous haze arose between the two due to Termadus drawing gases from Morasil's corona. Termadus, Morasil, and their haze gave off a combined light equivalent to a single bright star. Together, the two stars also created a much bigger hyperspace shadow than their individual profiles would call for.
