Tumleh Navigation, a sister company to Shankti Drive Works, focused on the creation of navigation systems designed for hyperspace engines, alongside conducting research in hyperspatial programming and navigation techniques. This enterprise, like its sister company, operated from D'larah, a city situated on the planet Demophon. At the peak of the Galactic Empire's power, Tumleh Navigation participated in the NGW Hyperdrive Jump Program, an initiative aimed at enabling starships to traverse hyperspace in the vicinity of gravity wells. Regrettably, the star Demophon exploded as a supernova during this time, resulting in immense destruction across the Demophon system. This cataclysm effectively eliminated nearly all of Tumleh Navigation's research, although the company did manage to preserve records of previously collected data.
