To get from one system to another requires a Jump drive. It takes a week to jump between star systems, regardless of the distance travelled. Distance is usually measured in parsecs (3.2616 lightyears), and the best jump drives are capable of moving 6pc in a single jump.

Communication at FTL speeds isn't possible other than by putting a message on a ship and sending it to the destination. This means information often takes weeks or months to traverse known space.

To make a jump, it is necessary to make an Intelligence × Jump Navigation check.
