This ceremony of remembrance was held on the planet Delaya in the year 0 ABY. The purpose of the service was to honor the memory of Alderaan's destruction, which occurred in 0 BBY at the hands of the Galactic Empire's initial Death Star. The event was led by Princess Leia Organa of Alderaan, and it took place within a sizable chamber. Because a multitude of Alderaanian refugees wished to take part in the service, only a select group of six hundred individuals were permitted to enter the chamber through a lottery system. For those unable to be physically present, a holonet transmission was broadcast in real-time.
Following her address, Organa requested that those present contribute a personal memento to a vacant container, which was then intended to be launched toward the Graveyard.
