Upon receiving a tip from one of his contacts, Ezra led the Rebels to Nixus Hub 218 on a rescue mission, where his contact said that two refugees were being held prisoner by the Galactic Empire. The Rebels arrived to find the refugees being led out of a cargo container at gunpoint, and they realize who the refugees are: two Lasat who survived the fall of Lasan. Zeb was shocked, having believed himself to be the last of the Lasat, and the rebels quickly attack the stormtroopers and Imperial officer in order to free the Lasat prisoners. Afterwards, the Rebels were greeted by Ezra's contact, who turned out to be Hondo Ohnaka. The two Lasats were known as Chava the wise and Gron, and both recognized Zeb as the former captain of the Lasan Honor Guard, much to Zeb's discomfort. His fellow Rebels were surprised, as Zeb never told them that he was captain of the Honor Guard. Zeb dismissed it, saying only that it was a long time and he had forgotten that life. With reinforcements bound to show up, the Rebels begin the return trip back to the Ghost. Hondo asked for the payment he was promised, only to discover that Ezra deceived him, leaving the Weequay pirate proud of his young friend. Just after the Rebels leave, a squadron of Stormtroopers came across Hondo. Always one to make a profit and double cross his friends if necessary, Hondo pointed the Stormtroopers in the direction of the Rebels.
While heading back to the ship, Ezra asked Chava about where they were headed. She told him they were on a journey to their new world, Lira San, a world described in prophecy as a safe system where the Lasat could begin a new life. Zeb did not believe in prophecies, however, nor did he believe in a future for his people. As this was discussed, Hondo led the troopers to the Rebels, and the soldiers informed Agent Kallus, who told them to capture the Rebels alive and that he would be there soon. As the troopers moved in to intercept, Hondo contacted Ezra and warned him about the impending threat. The Stormtroopers showed up and began a firefight with the Rebels, cornering them in the Nixus halls. To save his friend, Hondo quietly sealed a few doors, cutting many of the Stormtroopers off from the Rebels. The Rebels were able to fight their way back to the Ghost and take off, while Hondo was found and captured by other Stormtroopers. The Ghost departed from Nixus and escaped to hyperspace just as Agent Kallus and Admiral Konstantine arrived.
Safely in hyperspace, the Rebels learnt from Chava that she did not know the location of Lira San, as it was uncharted and from an ancient Lasat legend. In order to find it, Chava stated the "child" of prophecy must first save "the warrior" and "the fool." With Ezra's participation, Chava began a ritual designed to guide them to their new world. While everyone else was supportive, Zeb remained distant as if he did not want any part of it. Puzzled by his friend's reluctance, Ezra left the ritual preparations and spoke to Zeb, who explained that he felt guilty for failing to protect his people when the Empire destroyed them. As captain of the honour guard, he was responsible for protecting the royal family and all the Lasat. Though he fought to the end, Lasan was lost to the Empire and most of the Lasat were killed. Despite his friend's guilt and shame, Ezra encouraged Zeb to take this opportunity to protect his people again by helping Chava and Gron find Lira San. This encouragement helped Zeb overcome his guilt, and participates in the ritual. He assembled his bo-rifle in the way the ancient Lasat once did, allowing it to interact with Chava's staff. Chopper activated a map of the galaxy, and the bo-rifle created a surge of electricity that pointed to an uncharted world in Wild Space. Realizing the prophecy could be true, the Rebels plotted a course beyond the Outer Rim Territories.
As the Ghost neared the edge of the Outer Rim, Hera was forced to bring the ship out of hyperspace because a huge imploded star cluster stood in their path. Any starship that approached the maelstrom could get destroyed by the gravity field within the cluster. Chava recognized it as the maze referenced in the prophecy, meaning that Lira San lied somewhere within or beyond the cluster. Just then, Agent Kallus’ ship emerged from hypserspace, thanks to Hondo’s assistance and a tracker he placed on the communications device he gave to Ezra. Agent Kallus gave them one minute to surrender, otherwise he would order an attack on their ship. Chava stated that Kallus was the warrior that the prophecy spoke of, and explains to a perplexed Zeb that there were many warriors, fools, and children. A child saw things not as they were but how they could be, the fool denied his destiny, and the warrior created his own destiny. Chava said that no one was ever just one of them, but rather, in time, became all of them. Realizing that Chava's wisdom meant that he had to help forge his destiny and the destiny of the Lasat, Zeb used the power generated from his bo-rifle to navigate the Ghost into the cluster, leading the way to Lira San. Noticing the Rebels were attempting to escape, Kallus deployed two TIE Fighters to pursue them, but as they moved in they were ripped apart by the gravitational forces of the star cluster, while the Ghost made it through unharmed. Kallus' ship opened fire, but each shot deflected in opposite directions. Soon the haul of his ship began to buckle from the gravity fields. Kallus was forced to turn back, but took pleasure in knowing that the Rebels would be destroyed by the cluster. Against his expectations, however, the Ghost was able to safely make it through the gravity field, and the hyperdrive automatically kicked in and sent the Ghost into the middle of the star cluster.
While in the jump to hyperspace, the Rebels were surrounded by a blinding light and were knocked unconscious. They woke up to find themselves in unknown space, but realized they had found the planet of Lira San, much to the joy of the three Lasat. Zeb used the Phantom to bring Chava and Gron to the surface, while the others stayed behind. Ezra and Kanan talked about whether Zeb would stay with his people, but Kanan suspected he would return. Once he did, he brought happy news that Lira San was already inhabited by millions of Lasat. It turned out that Lira San was the original homeworld of the Lasat. Zeb felt proud of what he helped accomplish, and because the Ghost had made it through the maelstrom once, they now knew the safe course to Lira San. With that, Zeb resolved to guide any other surviving Lasat he finds to their new home.

- Originally this episode was titled "Legacy of Lasan", but it was changed to "Legends of the Lasat" after the mid-season finale was itself named "Legacy".
- The music used in this episode was inspired by the minimalist works of Philip Glass.
- The Lasats believe in a Spirit of the Galaxy, called the Ashla. Kanan gives the explanation that "The Force has many names" to different cultures (as they discovered it in their own histories, before developing spaceflight and joining the larger galactic community, etc.) In some of George Lucas's early draft treatments for the original Star Wars, he actually developed proper names for two sides of the Force: the Light side was called "Ashla" and the Dark side was called "Bogan". These proper names were dropped by the final version.
- When meeting Gron, he was originally going to tell Zeb "We are living evidence of their crime on Lasan. To hide the legacy of their evil, they would wipe our kind from the galaxy forever."
