Dune is a story about intergalactic politics, among several thousand other things. The main characters are born into noble families with millennia of legacy and endless power. Millions of humans die in the ages-old feud between House Atreides and House Harkonnen. Most wars are fought for resources, like the spice melange. If there's one group with a secure political position in the Dune universe, it's the Spacing Guild. No one can get anywhere without them.

Every space-faring sci-fi story invents or borrows a way to travel faster than light. Some explanations hang on suspension of disbelief, while others take elements of scientific truth. Dune uses a fictional theory called the Holtzman Effect to bend spacetime, folding reality to place the vehicle at the desired location instantaneously. As the Spacing Guild will illuminate, that endeavor comes with challenges.

How did the Spacing Guild form?

Like almost every element of Dune, the story of the Spacing Guild starts with the Butlerian Jihad. The Jihad was a galaxy-spanning war against thinking machines that ended with the religious extermination of any technology more complex than a calculator. During the Jihad, humanity raced to develop non-thinking machines to defeat the robot gods. An inventor named Tio Holtzman discovered the Holtzman Effect. He hires Norma Cenva, a brilliant young mathematician. When she devises several new applications for the Holtzman Effect, Holtzman takes credit for her accomplishments.

Though Norma doesn't want the fame her inventions would bring her, Holtzman fears her genius and fires her. Holtzman dies in a slave revolt shortly after, leaving Norma to work alone. A man in a robot body captures and tortures Norma, accidentally awakening her psychic abilities. She foresees the development of foldspace technology, allowing her to escalate its timeline. Norma developed the first foldspace engine and a ship to wield it. Her lover, Aurelius Venport, took credit, another man going down in history for her work. Their son, Adrien, used her accomplishment to found the Foldspace Shipping Company.

Norma's prescience makes her an impossibly savvy figure. She's never mentioned in the original Dune, but the extended universe makes her one of the most critical characters in the narrative. She watches the Foldspace Shipping Company gradually consume the concept of faster-than-light travel. Its monopoly is enforced through violence. Norma's great-grandson, Josef Venport, starts trouble with House Corrino, the family of the Emperor. He assassinates Emperor Salvador Corrino, evoking the wrath of his brother and successor. Norma uses her descendent as bait, striking a deal with new Emperor Roderick Corrino. She promises to give him Josef if he promises her safety for her navigators, consistent flows of the spice melange, and an independent Spacing Guild. She made Josef a navigator, exploiting their agreement to get everything she wanted without sacrifice.

How does the Spacing Guild work?

The Spacing Guild is secretive. Its hierarchy is unknown, and its higher-ups are shrouded in mystery. There is a Chief Administrator, managers, and other bureaucrats, but they typically go unnamed. The most critical and sought-after role in the Spacing Guild is as a Navigator. Guild Navigators are mutated humans capable of anticipating the unpredictable nature of faster-than-light travel. Foldspace engines were previously wildly unsafe, with at least one in every eight crashing. Guild Navigators are in endless demand, making them invaluable to the noble houses and every notable space-faring company.

Guild Navigators are regularly immersed in gaseous orange spice, a unique resource that only appears naturally on Arrakis. They spend most of their time in spice tanks, causing bizarre mutations. They're often described as fish-like humanoids with elongated limbs, massive heads, and unnaturally blue eyes. Guild Navigators train their minds to use the spice's psychic potential. They predict the future, allowing them to make split-second calculations while traveling faster than light. The Spacing Guild has monopolized their techniques, as they do on the foldspace engines that enable them. This, in turn, creates a necessary dependence on the spice melange. If the spice doesn't flow, humanity loses its ability to travel through space. Princess Irulan, in the opening of David Lynch's film adaptation of Dune, offers this brief summary:

The Spacing Guild and its navigators, who the spice has mutated over four-thousand years, use the orange spice gas, which gives them the ability to fold space. That is, travel to any part of the Universe without moving.

The Spacing Guild is one of the three powers that control the universe. The Noble Houses squabble for territory under the might of the Padishah Emperor, but the Spacing Guild got where it is by offering a vital service. It took one precognitive genius to establish an all-consuming monopoly on the concept of faster-than-light travel. The stories burn her accomplishments, but through the efforts of Norma Cenva, the Spacing Guild maintains one of the most important positions in the galaxy.
