Star Trek Picard: Every Easter Egg & Hidden Reference From 'Et In Arcadia Ego, Part 1'

Auntie Raffi identifies Coppelius as a class M planet, smaller and denser than Earth. The class M designation has been used to describe most Earth-like planets that have appeared in Star Trek, dating all the way back to the first TOS pilot "The Cage". Star Trek: Enterprise later used the Vulcan term Minshara-class in the episode "Strange New World", indicating the origin of the M.

Picard, Agnes, Rios, Soji, and Raffi approach the small settlement, Coppelius Station, which Soji thinks is her birthplace. The settlement is in reality a CGI-augmented mansion in Malibu, California called "Temple of Muses".

The inhabitants of Synthville are numerous androids with varying shades of Data-gold skin and yellow eyes. Their earth tone costumes recall the toga-like costumes that have been peppered throughout Trek's history of idyllic planets, especially the Edo world seen in the TNG episode "Justice". Though in this episode it's an android planet, not an orgy planet...

Some of the androids are playing three-dimensional chess, another Trek staple. This game first appeared in that other TOS pilot "Where No Man Has Gone Before" and appeared in every incarnation of the franchise, including Star Trek: Discovery where a game played by Michael Burnham and Spock was a major plot point of the episode "Project Daedalus".
