Kryllian
From Tardis Wiki, the free Doctor Who reference
Kryllians were a primitive humanoid species from the Eighth Moon of Gorgus. They used a distress signal to draw unsuspecting ships towards the moon, where they would be overcome by its intense gravity and crash, leaving their cargo and crew defenceless. The Kryllians then sold these crew as slaves to their masters, the Vogans. (COMIC: The Wreckers)
