The tempo-spatial corridor endpoints points between one star system and another is called a Kelheim Gate.  Kelheim Gate Source (KGS) refers to the entry point.  Kelheim Gate Terminus (KGT) therefore refers to the destination/exit point.
The breakthrough in faster-than-light (FTL) travel came when researchers discovered that each observable region of space (the more distant, the less precise) possessed a unique system frequency (fg) which was based on the largest, most stable star(s) in the “target space.”  Earlier studies had found slight but demonstrable appearances of small particles that seemed to appear out of the ether to Conglomerate quantum aberration detection arrays suggesting the existence of a “tunneling” mechanism of some sort (since called temporary micro-wormholes).  Dr. Nomura Kensuke and Dr. Chaitanya Singh devoted their studies to predicting the emergence of these tunnels in hopes of gaining the knowledge to artificially create them.  In the meantime, a massive effort was underway by a separate branch of Conglomerate Cosmos Catalogue & Research (CCCR), whose existence was based on the gamble that such research was paramount to eventual FTL travel.
The first executable WARP gate theories arose from Dr. Singh’s astrophysics protégé, Harry Kelheim.  As the Chief Science Assistant to Dr. Singh, Kelheim had unusually fluid access to the theoretical equations as well as the raw data and systems being gathered by the CCCR organization.  Kelheim’s groundbreaking research opened FTL travel to The Conglomerate.  The gateways which eventually resulted from his work now bear his name.
