Delta IV - Class M - United Federation of Planets
Native Species: Deltans
Location: Delta Triciatu system
Affiliation: United Federation of Planets
Population: 3.8 Billion
Delta (or Dhei) is the fourth planet of the Delta Triciatu system. It has two moons, Cinera and Seyann. It is homeworld of the Deltan species, and is governed by the Deltan Union, which joined the United Federation of Planets in 2223. As of 2380, the planet had a population of 3.8 billion Deltans. This usually bald species is known for being highly developed in the arena of sexuality.
A number of Deltans have served in Starfleet, including USS Enterprise navigator Lieutenant Ilia in the early 2270s. Willard Decker served on Delta IV, where, at the time, he met Ilia.
Delta IV's unpredictable tides and otherwise inhospitable ecology have promoted a culture at once polyglot and unified. Although many microcultures evolved throughout the expansive planetary chain of island archipelagos, they could never remain isolated long enough to develop either xenophobia or devastating cultural and technological advantages over one another. To forestall inbreeding, the island-bound Deltans also cultivated an extremely open sexual culture. Indeed, stranded mariners were often adopted into large group amours in order to refresh local gene pools. Brought together by ties of sex and geography, Deltans learned to peacefully coexist and relate well, by necessity. With the bountiful, renewable resources of so flourishing a natural environment, and a low species birthrate, wars over resources were almost unknown among the Deltans.
The Deltans were also drawn to cultural unity by their genetic predisposition toward empathy along with related psionic abilities. The capacity to experience another's suffering rendered violence and armed conflict anathema, and even excessively hurtful personality conflict and quarrel, unthinkably impolite. Yet ordinary social hypocrisy was impossible due to the intense Deltan pheromones and acute sensitivity thereto, rendering Deltans so transparent to one another, emotionally. And so, their culture evolved toward a remarkable global ideal of supportive, nurturing behavior founded upon time-honored Deltan sexual openness. A deep-rooted sense of species and personal security remains unshaken by their subsequent contact with the Andorians and later other starfaring cultures of the Beta Quadrant. Their greatest concession to existence in a dangerous galaxy was the adoption of the renowned Oath of Celibacy out of necessity and good manners when dealing with those whom they came to regard, perhaps with somewhat patronizing deference, as less sexually-mature species and cultures.
