Mos Espa is one of few port cities on Tatooine, born out of the desert and built piece by piece over many years. Domed buildings protect the citizens against the glare of the twin suns and the scorching heat. Among the dwellings, workspaces, and commercial operations of many bizarre kinds there are also entertainment areas, including some of colossal scale. The famed Mos Espa Grand Arena can can hold an audience almost as large as the city's entire population.
Most of Mos Espa's inhabitants are settlers and subsistence earners who scratch out a meager living as best they can. The only real wealth in Mos Espa is tied up in gambling and off-world trade, especially in the lucrative black market beyond the trade laws and controls of the galactic government.
In the time of the Republic, slavery persisted in Mos Espa, though the despicable trade was outlawed elsewhere. An entire section of the city's outskirts had been transformed into a Slave Quarter. Live slaves functioned more as prestige possessions than cheap laborers, and owners parted with them only reluctantly. Slaves could even find themselves used as capital in business transactions. The true powers in control of Mos Espa were the Hutt gangsters, who found slavery a useful institution for their purposes, and Tatooine's remoteness allowed them to practice their illegal ventures.

A shrewd and gruff proprietor of a junk shop in Mos Espa, Watto is a crabby, unshaven Toydarian with a love of credits and gambling. Although considered one of the smaller shops of Mos Espa, Watto's junkyard was nonetheless a treasure trove of discarded machinery and spare parts.
Among Watto's possessions were the slaves Anakin and Shmi Skywalker. Having won them from Gardulla the Hutt in a Podracing bet, Watto put them both to work in his shop. Young Anakin showed an incredible talent for machinery repair, and Watto took a shine to the boy. Even though he was unscrupulous enough to keep a slave, Watto was a fair master. It most probably had to do with the fact that the boy was a prime source of income for Watto, not only in keeping his machinery running, but also actually competing for Watto in the Podraces.
Anakin was an incredible pilot, the only human known to compete in the dangerous high-speed sport of Podracing. But in races where Anakin would compete against the shifty Dug Sebulba, Watto would always bet on the latter because, as Watto says, "he always wins!"
Watto's greed and gambling got the better of him one day when a mysterious outlander came to his shop to barter a deal for starship parts. The Toydarian ended up not only betting all his money away, but also Anakin's freedom. Sebulba failed to finish the Boonta Eve Classic, and Anakin came in first. Watto lost everything.
Desperate to recoup some of his losses, Watto eventually sold Shmi Skywalker to a moisture farmer named Cliegg Lars. The down-on-his-luck trader reported as much to a grown Anakin Skywalker. The young Jedi had returned to Tatooine a decade after his departure in search of his mother.
Watto is a stout, blue-skinned Toydarian, with rapidly flapping wings that keep him hovering at about a meter off the ground. The craggy-toothed merchant not only has a knack for haggling, but also cannot be affected by Jedi mind tricks.

The bone-chilling cold is not the only danger that awaits a traveler on the Hoth plains. Despite standing over two meters in height, the wampa ice creature is nonetheless a stealthy predator. Its white fur is the perfect camouflage, and the howling Hoth winds mask its approach until it is too late. With a crushing blow from its clawed hand, a wampa is strong enough to snap the neck of even a hardy tauntaun.
Wampas live in caves carved from the Hoth ice. It is here that the ice creature drags its prey. It suspends its victims from the cave ceiling until it is ready to feast.
The Rebels were plagued with wampa attacks when they erected their hidden base on Hoth. Commander Luke Skywalker was savagely attacked by a wampa while on scouting duty. Skywalker narrowly escaped becoming a meal and dying in a Hoth blizzard. Despite bacta treatment administered by the skilled medical droid 2-1B, Luke still bears scars from that encounter.
Just prior to the evacuation of the Hoth base, the Rebels had to deal with repeated wampa attacks. The first indication that was something amiss was the discovery of a dead tauntaun, its neck mysteriously broken. Attracted to the sound of astromech droids, several wampa ice creatures penetrated deeper and deeper into the Alliance caverns. The Rebels were able to capture at least one wampa in a pen before having to abandon Echo Base altogether.
The All Terrain Armored Transport, or AT-AT walker, is a four-legged transport and combat vehicle used by the Imperial ground forces. Standing a towering 15 meters tall, these walkers are intimidating, and are used as much for psychological effect as they are for tactical effect.
An AT-AT has blast-impervious armor plating, and resembles a gigantic beast as it moves across the battlefield. An AT-AT's head carries the main armaments, a pair of light blasters located on the walker's "temples," and heavier, twin laser cannons mounted on the walker's "chin."
The command crew pilots the AT-AT from the walker's head, which is connected to the main body by a flexible neck. The crew consists of a commander, a gunner, and a pilot. Additional crews and troops can be carried in the walker's main storage bay.

Located in the Hoth system is a chaotic asteroid field filled with dangerous swarms of colliding rocks. Stray bodies from the field get caught in Hoth's gravity well, and enter the ice planet's atmosphere, becoming meteorites.
If the threat of being crushed by massive asteroids is not enough to deter the most foolhardy pilot, the asteroid field is also home to dangerous lifeforms. At least one unbelievably huge space slug has made a home out of one of the larger asteroids. Furthermore, the field is infested by mynocks, leathery-winged energy parasites that attach themselves to passing ships and then chew on the power cables.
The odds of successfully navigating an asteroid field are approximately 3,720 to 1. Han Solo, never being too concerned with the odds, recklessly plunged the Millennium Falcon into the field to escape Imperial pursuit after the Battle of Hoth.
On the outskirts of Mos Espa was an immense venue for watching the popular Boonta Eve Classic Podrace. Over one hundred thousands beings filled the Mos Espa Grand Arena to capacity during the annual event. They filed into the grandstand seats, crowded into broad viewing platforms or clustered into the upper tiers to catch a glimpse of the high-speed spectacle. For a modest fee, spectators could rent hand-held viewscreens which displayed images recorded by fast-flying Podrace holocams tracking the race. From a distance, the arena's seats looked to be a flowing tapestry of color, as race-fans from all throughout the Outer Rim Territories congregated. Alien food vendors roamed the crowds, offering exotic wares, bands both amateur and professional tootled race themes and popular melodies to cheer on their favored pilots, fans brandished flags bearing their racer's emblems.
The wealthier of Mos Espa's residents and guests could afford private viewing boxes separated from the rest of the rabble. The Toydarian junk-merchant Watto hosted viewing parties for his friends and gambling partners. The most opulent of viewing boxes was reserved for the ruling Hutts, particularly Jabba the Hutt, who hosted the Boonta Eve Classic.
After abandoning their headquarters at the Massassi outpost on Yavin 4, the core group of the Rebel Alliance established Echo Base on the Hoth. Alliance engineers worked non-stop to adapt their technology to withstand the subzero temperature extremes of the frigid ice planet. When the technicians were unable to get the T-47s functioning in time, the Rebels domesticated the indigenous tauntaun for use as a patrol mount.
The nerve center of Echo Base was its darkened command center, where General Rieekan issued orders to the rest of his troops. Here, Alliance scanner operators carefully monitored incoming data from the scattered sensors placed by Rebel scouts in the Hoth wilderness.
Protecting Echo Base was a powerful energy shield strong enough to deflect Imperial bombardment. When the Empire arrived in the Hoth system, the Rebels erected the shield, forcing the Imperials to engage in a ground battle. The Rebels speedily evacuated the personnel and equipment they could aboard Rebel transports with starfighter escorts, offering covering fire for the fleeing ships from a massive ground-based ion cannon.
As the transports retreated, the Rebel ground forces and snowspeeder squadrons covered their escape by delaying the Imperials for as long as they could. Rebel troopers dug into snowy trenches, blasting at the incoming Imperials with turret-mounted laser cannons and blaster rifles. The Imperial walkers were unstoppable. The Rebels were routed and Echo Base was overrun.
