The Nygeans are a spacefaring humanoid species native to the Delta Quadrant. In appearance Nygeans are identical to humans except for bone ridges above their nose, on their chin and a "rippled" effect on their foreheads.
The Nygeans govern a sector of space which is home to several different species. Their technology seems at least equal to that of Federation science. They have something akin to warp drive including plasma conduits. The Nygeans are also familiar with matter transportation.
