Mission to rescue the survivors of Alderaan

During the Galactic Civil War, Princess Leia Organa undertook a mission to save the few Alderaanians left living in galaxy after her homeworld of Alderaan was destroyed by the Death Star. Following the Disaster, the Galactic Empire sought out surviving Alderaanians in an attempt to eradicate them, and Organa set out with Rebel pilot Evaan Verlaine and astromech droid R2-D2 to rescue them. They first fled from the Great Temple of Massassi, the Rebel's base on Yavin 4, over the objections of General Jan Dodonna. After escaping, they made their way to the planet Naboo, where they rescued a group of Alderaanian musicians called Melodic Order, before heading for Sullust. Unknown to Organa and her followers was that the Empire was tracking their movements.

Prelude
"As we speak, the Imperials are hunting down all surviving Alderaanians." "All? How do you know?" "Word travels through the Rebel forces. Too much so to simply be rumor."

During the Galactic Civil War, Grand Moff Wilhuff Tarkin used the Death Star to destroy the planet Alderaan as a means of demonstrating the firepower of the Galactic Empire's deep space mobile battle station. Alderaan's destruction killed the millions of beings who lived on the planet and left only a small handful of Alderaanians alive in the galaxy. The Empire targeted the remaining Alderaanians with the intent of killing them as well and eradicating the culture of Alderaan, a planet that the Empire had seen as a hotbed of rebellious activity &mdash;Alderaan's leaders, including Viceroy Bail Organa and Senator Leia Organa, were leading members of the Alliance to Restore the Republic. The Empire's efforts were spread throughout the galaxy, including on the Imperial capital of Coruscant. The planet's Alderaanian population took to calling their world's destruction "the Disaster," and the people broke out into riots that led to mass arrests and killings.

Shortly after the Disaster, the Rebel Alliance launched the Battle of Yavin. The Rebel pilot Luke Skywalker destroyed the Death Star, thus sparing more planets from meeting Alderaan's fate. The Rebels celebrated their victory in the Great Temple of Massassi, their base on Yavin 4, and prepared to evacuate due to the Empire having learned their location. As the base was being packed up, Princess Organa&mdash;the last surviving member of House of Organa, Alderaan's ruling family&mdash;met Rebel pilot Evaan Verlaine. The pilot shared rumors she heard with the princess, rumors saying that the Empire was hunting down surviving Alderaanians. Organa resolved to find and protect the rest of her people, and Verlaine swore loyalty to the princess&mdash;who she saw as the new Queen of Alderaan&mdash;and the two set out on a mission to save their surviving Alderaanian brothers and sisters.
