Triexian

Triexians are a race native to the planet Triex in the Alpha Quadrant. Triexians are distinguished by their three arms, three legs, an enlongated skull, and orange to pink-hued skin. Triexians bear some superficial resemblences to Edosians.

Triexians are a long-lived species, with lifespans stretching centuries. Elder Triexians will lapse into a death-like state every twenty-five years, then molt their skins and re-emerge in what is called the Rebirth.

Many Triexians have served in Starfleet over the years, including Lieutenant Arex Na Eth. (NF novel: Cold Wars; short story: "The Road to Edos")

Niryx Ta Sef was a Starfleet officer who served on the USS Pendragon in the 24th century.
