On X.com, a screenwriter named Zack Stentz writes (with a clip), "This episode was written by beloved horror author Robert Bloch, who's doing an homage to his friend and mentor H.P. Lovecraft's novella "At The Mountains of Madness," also about a race of artificially created servants who destroyed their creators (also called "the Old Ones.")
Apparently it's this episode. I wonder if RAW spotted it?
The costuming would appear to be a tribute to some of the old covers SF magazines used to have.
