Hysk

The Hysk were an extinct race of giant, upright insects with multiple caliper-limbs and concentric mandibles, known throughout as being "oppressive, totalitarian, unmerciful and antisocial" creatures.

It was UniMedia Franchise Orbital (largest off-world news conglomerate in the Spiral) that sought to exploit these creatures as objects of fear. For hundreds of years, long after their extinction, they generated a hologram (identifying itself as Myskhurr) and reproducing the illegal drug Chronex (which gave the illusion of extending life while ultimately bringing death). All this was to command the ratings in a scandal that nearly ran across the colonies before being exposed by one of their reporters (Huksley) aided by the Seventh Doctor. (DWM: The Infinity Season)
