Trouble Beyond the Borders
An FTL drive
In the DJ’verse, the Hyperdrive is the main FTL drive used to power small ships. Large freight ships still use the old Null Drive through the Jump Gates. Currently (no pun intended) hyperdrives are generally powered by large batteries with a small graviticly enhanced nuclear reactor and perhaps a solar panel and mirrors.
The hyperdrive allows for changes in course while under way, and it allows for entering and exiting hyperdrive from almost anywhere space is fairly flat, much like the Traveller 100 D points.
