A Wormhole is a manipulation of the fabric of time-space where two non-adjacent points are pinched together allowing matter to travel quickly between point A and point B. Practically, if point A and B are far enough apart it allows for faster-than-light travel by essentially folding the fabric of time-space onto itself and creating a "shortcut". This is the basis for many modern, as well as ancient, technologies such as skipdrives and void kith.
