The business of Ventura, of which there is much, is pleasure. It exists to support the massive casinos that are suspended by a web of anti-gravity units above the surface of the planet.
Ventura is home to the mystical Luck Lords, beings who gather the power of chaotic chance in an attempt to influence the universe in accord with their grand designs. Living atop the Ziggurat of Ventura, a mountain in an uninhabited area of the planet, the Lords appear only during times of specific cosmic convergences. They remove themselves to an unknown locale for contemplation during the times between these stellar events.
Most of Ventura is inhabitable and quite fertile, but the rents charged to work the land by the wealthy casino owners who own the world are too high for anyone to pay. The casino owners are among the wealthiest sentient beings in the 30th Century universe; all industry that exists on world is owned by these casino owners and exists to support the magical gambling palaces hovering above the planet's surface.
The casinos are a gambler's paradise, offering, in addition to most known games of chance in the universe, an atmosphere of menace, which is intentionally designed into the environment. This ambiance is perhaps the most prominent feature of the planet, one that brings the tourists back to the Venturan casinos.
