The son of Han Solo and Leia Organa, Ben Solo was seduced by the dark side of the Force and renamed himself Kylo Ren, becoming the First Order’s champion and Supreme Leader Snoke’s student. Kylo killed his father and seeks to destroy his mother’s Resistance and the remnants of the Jedi Order. Though a servant of the dark side, he still struggles against the pull of the light side of the Force.

A capital ship built on a nearly unimaginable scale, the Supremacy is a vast flying wing more than 60 kilometers wide. In addition to being a warship with enormous firepower, it serves Supreme Leader Snoke as throne room and the First Order as mobile capital. Its vast interior houses army training grounds, shipyards, production lines and R&D labs. The mighty ship was torn in two before the Battle of Crait, ripped apart when Vice Admiral Holdo sent the Raddus into hyperspace along a path that passed through the larger craft.

The New Republic’s rise reduced the once-mighty Empire to a rump state hemmed in by strict disarmament treaties and punishing reparations. But in the galaxy’s Unknown Regions, former Imperial officers, nobles and technologists plotted a return to power, building fleets and armies in secret. This movement became the First Order, ruled by Supreme Leader Snoke, and is now ready to reclaim the Imperial legacy.

The Supreme Leader of the First Order, the mysterious Snoke has no permanent base of operations, preferring to contact his underlings from a mobile command post. Snoke is powerful with the dark side of the Force, and seduced Ben Solo into abandoning the Jedi path to become his apprentice. But Snoke also commands General Hux and the technological war machine the First Order has engineered to destroy the New Republic and Leia Organa’s Resistance. Snoke used the Force to connect Ben and Rey in hopes of finding Luke Skywalker’s planet of exile. His plan succeeded, but Ben turned on him, cleaving him in two with Skywalker’s lightsaber.

Bacta tanks were cylindrical vessels filled with a liquid healing agent and used to treat seriously injured patients. To promote healing, patients were completely submerged and used breathing masks while recuperating. Clone troopers were treated in bacta at facilities such as the Kaliida Shoals Medical Center; after he was injured by a wampa, Luke Skywalker recovered in a bacta tank at Hoth’s Echo Base.

Made of durable flexpoly, bacta suits circulate healing bacta fluid to damaged tissues in situations where a patient can’t be suspended in a full tank. Resistance medics place an unconscious Finn in an emergency bacta suit for the evacuation of D’Qar.
