When Organa traveled to the Paucris system to warn a rebel base there that the Empire planned to investigate the system, Domadi, who Organa had contacted beforehand to tell him about her mission as explanation for why she had to cancel plans to meet him, followed in a cutter in an attempt to gather more information on the rebels. He arrived in the system just as the orbital platforms that had been used by the rebels were about to self-destruct. Organa, horrified when she realized who was piloting the ship, attempted to warn him, but the warning came too late and Domadi's ship was severely damaged by the explosions. He was mortally injured from the shockwave, and when Organa boarded his ship, he told her about his collection of information and asked her to turn in the memory rod with the data before dying. Organa instead took Domadi's body aboard her ship, and left the memory rod aboard Domadi's cutter to burn up in Paucris Major's atmosphere. Domadi's parents were told that he had died saving Leia during a small-craft accident in Alderaan's upper atmosphere. After Domadi was buried on his homeworld, Organa placed a lock of Domadi's hair in her keepsake chest. By 28 ABY, the lock of hair was still in Organa's chest.
Kier Domadi first appeared in Leia, Princess of Alderaan a young adult novel written by Claudia Gray that was released on September 1, 2017. Gray stated that in her mind, Domadi was a young Rami Malek. She also explained that Domadi was effectively the anti-Han Solo, but having the same opinion that Leia ought to have a personal life.
