Siege of Lasan

"I was there when Lasan fell. I know why you fear those disruptors. I gave the order to use them."

- Agent Kallus, to Garazeb Orrelios

The fall of Lasan saw the near-extinction of the Lasat species under the military forces of the Galactic Empire. During the early years of the Empire, the Imperial Military brutally suppressed an uprising on the Lasat homeworld of Lasan. The conflict led to the near-extinction of the Lasat people and caused the Imperial Senate to ban T-7 ion disruptor rifles. Some Lasat survived, like Garazeb Orrelios, who later joined the rebellion, while others like Gron and Chava resettled on the mystical Lasat refuge of Lira San.

Prelude
The Lasat species originated on the remote planet of Lira San in Wild Space. At some unknown point, a large number of Lasat colonized the planet Lasan and eventually lost contact with their kin on Lira San. The Lasat on Lasan established a royal family and came to regard Lasan as their species' homeworld. Following the end of the Clone Wars, the Galactic Republic was transformed into the Galactic Empire. When the Lasat challenged the Empire, Imperial forces invaded Lasan.

History
Following an uprising on the species' homeworld of Lasan, Agent Kallus of the Imperial Security Bureau was tasked with wiping out the rebellion. It was he who ordered the Imperial soldiers to use T-7 ion disruptor rifles against the Lasat. After defeating a member of the Lasan High Honor Guard, the guard then gave him his J-19 bo-rifle in accordance with the Boosahn Keeraw, the Lasat warrior way. A number of Wookiee soldiers armed with weapons whittled from the wroshyr trees of their home planet also took part in the battle, sacrificing their own lives to try to prevent the massacres on Lasan. Thanks to the Wookiees' intervention, some Lasat were saved.

Among the Lasat who survived were Garazeb Orrelios, a captain in the Lasan High Honor Guard, and his grandmother. During the battle, Zeb was tasked with protecting the royal family and Lasat. However, he was knocked out by an explosion. When he awoke, Zeb found that everything had been destroyed and blamed himself for failing to carry out his duty. Zeb was haunted by his experiences during the Fall and harbored a deep hatred for the Empire. Those Lasat survivors who were captured by the Empire ended up in prison camps.

Aftermath
The fall of Lasan ended with the devastation of the planet and the near-extinction of the Lasat species. After the fall of Lasan, the Imperial Senate banned the use of the T-7 disruptors. However, the Empire secretly planned to acquire some of the last remaining stock to restart production of them on Lothal. However, their plan was disrupted by the Lothal rebels and R2-D2 who destroyed half of the ion disruptors and sold the rest to the crime lord Cikatro Vizago. During the skirmish, Kallus personally fought Zeb and taunted the Lasat about his role in the fall of Lasan.

Three years before the Battle of Yavin, the Lothal rebels helped two other Lasat refugees, the former Honor Guard Gron and the mystic Chava, to rediscover the planet Lira San. During the journey, Gron contended that Lasan had not been destroyed but had been merely transformed in order to fulfill an ancient Lasat prophecy around Lira San. This prophecy held that Lira San could only be found if a "child of Lasan" saved the the fool and the warrior from destruction. Following the rediscovery of Lira San, the rebels designated the planet as a sanctuary for other Lasat refugees.

Later, the fall of Lasan became a subject of conversation between Zeb and Agent Kallus. The two adversaries had become stranded on the ice moon of Bahryn following an Imperial ambush above Geonosis. After Kallus recounted how he had obtained his bo-rifle from a fallen Lasat warrior, Kallus confided that he had not expected the Empire to unleash a massacre on Lasan and stressed that this was nothing personal. Zeb reassured his adversary that he had made peace with the past already. As a gesture of reconciliation, Zeb presented Kallus with a Bahryn meteorite as a parting gift.
