Hyperspace was a dimension parallel to the normal universe allowing spaceships to travel up to 2.5 billion times the speed of light. It's use permitted the rise of the Star Imperium.

Some of the larger spaceships are equipped with an onboard Hyperdrive allowing them to enter and exit hyperspace relatively easily. Most spaceships, however, relied on Jumpgates to enter or exit hyperspace or were carried on board larger ships possessing their own hyperdrives.
