Lightfold Rail
The earliest form of light speed travel achieved over fifty years ago. This is the most common form of light speed travel for consumer-grade spacecraft, as most of those vehicles lack the technology to support a fully-functioning leap drive. These massive space stations essentially slingshot spacecraft to their destination.
Social Impact
The implementation of lightfold rail technology is what allowed our civilization to reach beyond the immediate area of Earth and its moon, serving as a catalyst for the rapid expansion of our species into the farthest reaches of the Anima Radix system.
