Inhabitants of an extra-galactic planet. A race of technologically-advanced beings that resemble huge centipedes that are slightly larger than a human. The populace worships an entity known as Juk-Shabb, which appears as a glowing, color-shifting orb. Very little is known about this deity other than it is telepathic and is greatly revered by the denizens of Yekub.
The Yekubians destroyed all intelligent life in the galaxy where they dwelt and sought to extend their influence throughout the universe. As part of their grand scheme, they sent out cube-shaped probes that could effect a mind-swap with any intelligent creature who found one. In this way, Yekubian agents could infiltrate the finder's world. One such cube landed on the Earth during the reign of the Great Race of Yith. When several of its members were taken over, the Yithians realized the danger of the cube and sequestered it under heavy guard. Eventually, however, the cube was lost.(From Wikipedia)
