Sedrons are family of fundamental particles that is unknown to human science.
For the first 100,000 years of the Huaoshy Space Age, space travel was constrained by the speed of light. However, the Huaoshy then discovered how to alter the dimensional structure of the universe so as to make possible faster-than-light travel through space. With that Huaoshy-engineered shift in dimensional structure, it became possible to produce sedrons and use them in extended three dimensional space to make possible faster-than-light space travel.
Sedronic Domain. The Huaoshy long ago transcended their biological nature and transformed themselves in to a form of artificial life that is composed of sedronic matter. The Huaoshy exist within a multi-dimensional domain where they can take full advantage of the fact that sedrons can exist in “compact dimensions”. The Huaoshy mostly allow the pek to manage the affairs of creatures (such as we humans) who are trapped in the three dimensional universe of conventional matter. However, in an emergency, the Huaoshy can intrude upon human affairs.
Time Travel was an unexpected consequence of the dimensional engineering that made possible FTL travel.
