The sixteenth anniversary of Leia Organa's original Name Day was marked by a ceremony known as the Day of Demand. On this day, she asserted her entitlement to the throne of Alderaan.
Leia Organa had been preparing for the Day of Demand and the speech she would give at the ceremony for months. Before the Day of Demand, Queen Breha engaged Leia in a deep discussion about love and duty. Breha brought the Rhindon Sword and placed it on Leia's bed, telling Leia she would fasten it to her waist on her wedding day, before she met her husband or wife. Breha also assured Leia that she would be able to choose her own spouse when the time came.
The banquet preparations filled the palace halls with enticing scents. Low, dark clouds hung heavily over the city of Aldera on that day, eventually turning into a thunderstorm later that night. The Crown of Alderaan was brought from the museum, its usual location, to the palace for the ceremony. Before the ceremony, Leia's attendant droid WA-2V assisted her in getting ready, agreeing on a simple white dress for Leia, complete with a cape, and striking silver jewelry for TooVee. TooVee also styled Leia's hair in the traditional intricate manner, adding a silver headband that fit snugly into Leia's braids, featuring a pearl charm hanging at the center of Leia's forehead.
During the ceremony, Organa staked her claim to the Alderaanian throne. She presented three challenges, one each of the body, heart, and mind, while holding the Rhindon Sword. She addressed her parents, Queen Breha Organa, who was adorned in bronze silk with beaded braids, and Viceroy Bail Organa, who wore the traditional viceroy's long jacket.
Despite the temptation to improvise, perhaps by declaring her intention to learn juggling and feather-fire dancing, Leia delivered the speech she had diligently rehearsed for months, reciting it almost automatically. For her Challenge of the Body, Leia would ascend to the peak of the Alderaanian mountain Appenza Peak. For the Challenge of the Mind, she would represent Alderaan in the Apprentice Legislature. And for her Challenge of the Heart, she would fund mercy missions to needy planets using her portion of the royal funds.
Among the attendees were several of Bail's allies from the Imperial Senate, including Mon Mothma of Chandrila and Cinderon Malpe of Derella. Initially, Bail and Breha beamed with pride after the ceremony. However, as the crowd approached, they shifted their attention to greeting them instead of congratulating their daughter. Bail engaged in conversation with Mon Mothma and her fellow Chandrilan senator Winmey Lenz, while Breha grasped the hands of Senator Tynnra Pamlo, expressing gratitude for her presence. Lord Mellowyn, a distant relative of her father's, greeted Leia, but she interpreted her parents' behavior as a sign of their waning affection, as they had been distancing themselves from her for the preceding six months.
Following her Day of Demand, Leia was permitted to partake in genuine Alderaanian wine, Toniray, instead of the diluted version she had previously consumed.
In 4 ABY, following the destruction of Alderaan, Leia became betrothed to Corellian Han Solo. Upon announcing the engagement to Mon Mothma, Mothma expressed her wish that Leia's parents could have been present, prompting Leia to recall the conversation she had with her mother before her Day of Demand.
