Grelladian

From Tardis Wiki, the free Doctor Who reference

The Grelladians were the blue-bronze skinned natives of the Star Grellades. They were quick learners, but completely subservient. They sold well in the markets on Gallifrey.

The Pythia's personal guard, Handstrong, was a Grelladian. (PROSE: Cat's Cradle: Time's Crucible)
