Quo Vadis is an interstellar cartography and routefinding service operating in the League and War Eras. It collates and distributes information on traffic, flight restrictions, warnings, and stellar data, for use by starship crews.

The data provided by Quo Vadis is collected from local traffic control centres, as well as voluntary contributions from travelling ships. Although it's still delayed by travel time, it is continuously updated, making it usually more up-to-date than waiting for requests for information to be answered.

During the War, the service faced controversy after it displayed warnings about military maneuvers that were supposed to be secret. A legal enforcement case brought by the Galactic Defense League was never resolved due to the end of the war.
