An uncharted planet of more than two hundred thousand androids, built by a vanished civilisation from Andromeda, which Harry Mudd names after himself in the episode I, Mudd.
Mudd is the name Harcourt Fenton Mudd gives to a barren Class K world where he lands while fleeing the law. Its underground complex houses androids left behind by the Makers, a race from the Andromeda galaxy who died out long ago. It appears in the original series episode I, Mudd.
The androids make Mudd their ruler and supply his every wish, but will not let him leave. He sends the android Norman to hijack the Enterprise and bring its crew as replacements. The androids then decide to take the ship themselves and protect humanity by controlling it.
Kirk's crew and Mudd defeat them with a display of nonsense and illogic that overloads Norman. Mudd is left behind, watched over by copies of his nagging wife Stella.
