There is something very fascinating about being able to travel from one part of the universe to another by entering a worm hole and skipping through a very large process. This is the only way for space travel to be possible for any species out there. Even the most advanced species are unable to handle traveling fast enough to perform this kind of journey. Even light speed is not fast enough, but the only barrier we have been able to break is the barrier of sound. Light speed is still unmatched by aircrafts.
The worm holes got created by a superior being that is a founding member of the order. They found the way to create these portals that allow people to jump over to other dimensions and areas of the universe without having to travel all the way to their destination. Thanks to this invention we have been able to explore many planets.
