The Risians or Risans were a humanoid species native to the Federation planet Risa. They resembled Humans save for a small button-like decoration on their foreheads. They also differed internally, such as that in the 2150s a Risian hospital would have difficulty treating a Human. (DS9: "Let He Who Is Without Sin..."; ENT: "Two Days and Two Nights")
History
Centuries ago, the Risians tamed the earthquakes and rainstorms of their homeworld by installing seismic regulators and a weather control system. By the mid-22nd century, Risa had become well-known as a cosmopolitan vacation destination. (DS9: "Let He Who Is Without Sin..."; ENT: "Two Days and Two Nights")
In 2368, Robin Lefler mistakenly referred to the Ktarian game as a "Risian gadget", as William Riker had brought it from Risa. (TNG: "The Game")
In 2374, Sirella insulted Jadzia Dax as being a "Risian slut" for hosting a rambunctious party instead of attending the Bre'Nan ritual. (DS9: "You Are Cordially Invited")
A Risian woman was present at Morn's memorial later that year. (DS9: "Who Mourns for Morn?")
In 2380, several Risians were present in a Risian district on Tulgana IV. (LD: "Envoys")
Culture
The Risians were known for their sexually permissive culture. The horga'hn, a Risian fertility symbol, was omnipresent in Risian culture. Any individual who displayed a horga'hn statuette indicated their receptiveness to jamaharon, a mysterious and pleasurable sexual practice. Risian women were described as "imaginative" by William Riker in 2366 and as "voluptuous" by Zek in 2369.(TNG: "Captain's Holiday"; DS9: "The Nagus", "Let He Who Is Without Sin...")
However, despite their reputation for hedonism, the Risians were also quite diligent and prided themselves on providing a good experience for vacationers. (DS9: "Let He Who Is Without Sin...")
The Lohlunat, or "Festival of the Moon", was a popular Risian celebration celebrated at Suraya Bay. (ENT: "Two Days and Two Nights")
The Risan language was not spoken by many non-Risians, as most visitors did not bother to learn it. (ENT: "Two Days and Two Nights")
