Iotian

Iotians are a humanoid race native to planet Sigma Iotia II, in the Alpha Quadrant.

First contact bewteen Iotians and the Federation was made in 2167 by the crew of the USS Horizon. This contact took place prior to the adoption of the Prime Directive, and resulted in significant cultural contamination, resulting in a society based on Earth's organized crime syndicates in the 1920s. An effort to rectify some of this damage was undertaken by Captain James T. Kirk during a follow-up visit in 2267. (TOS episode: "A Piece of the Action")

Following Kirk's visit, the Federation Council resolved to devote significant resources to guiding Iotian society, including large teams of cultural experts. (SCE eBook: Fables of the Prime Directive)

By the mid-24th century, Iotians were serving in Starfleet. (NF short story: "All That Glisters...", SCE eBook: The Demon, Book One)
