This species is a race of giant, tentacled space whale-like creatures who are rarely ever seen by travelers. Before they find the asteroid belt, however, the Rebels crew comes across a herd of Purrgil in the middle of open space. There, the guild was refining a gas known as Clouzon-36 to create fuel. In order to get more, not just for themselves but for the entire Rebel fleet, they locate an asteroid belt claimed by the Mining Guild. In the Star Wars: Rebels Season 2, the crew of the Ghost are running low on fuel.

RELATED: The Clone Wars' Next Episode Could Leave Rex In A Heartbreaking Position For a long time, hyperspace technology was just something that fans accepted as part of the Star Wars universe, never once questioning it. However, Star Wars: Rebels changed all of that with a surprising revelation. The technology is more or less available to anyone in the galaxy and, although it's sometimes problematic, it can easily be fixed. The Star Wars films and television series have shown that any ship enabled with a hyperdrive can perform the jump to light-speed, from A-Wings and the Razor Crest to Imperial Star Destroyers. Hyperspace travel has also been used to make rapid getaways, and even to create a devastating attack. This concept is what allows starships from both the Rebellion and the Empire to move from one corner of the galaxy to the other in relatively short amounts of time. The technology that allows spaceships to travel at light-speed was introduced in 1977's A New Hope, and it's been crucial in every film and television series since then.

Hyperspace travel is one of the basic foundations of the Star Wars franchise.
