Ledos
The surface of Ledos
Ledos is an inhabited M-class planet located in the Delta Quadrant. It is the home of the Ledosians, as well as their genetic offshoot, the Ventu.
While the Ledosians were highly advanced warp-capable species, the Ventu were a nomadic and simplistic people. Centuries ago, when aliens known only by their borg designation, Species 312, encountered their world, they constructed an energy barrier seperating the still primitve Ventu from the rest of their society.
Ledos has very strict rules governing starship pilots. Pilots deemed reckles can face consequences including a mandatory three day piloting course, or the revoking of their right to fly in Ledosion space.
In 2377 Ledos was visited by the USS Voyager, where they conducted shore-leave, and attended a conference. When a shuttle became trapped in the energy barrier, Seven of Nine and Chakotay were trapped within it. They interacted with the Ventu, who assist in treating their wounds.
The USS Voyager attempted to bring down the barrier using its phasers, to retrieve there crew, only to find it was already being brough down from the inside, by Seven of Nine.
The Ledosions were extremely grateful, and began sending research teams to study the Ventu. Realizing that the cultural contamination could destroy the Ventu society, Voyager re-initialized the barrier, and promptly left Ledos. (VOY: "Natural Law")
