Daizanna was a Human female who lived during the era of the Cold War. She took on the role of Joiner within the Iesei Killik nest, fully embracing her connection to it. The Iesei nest, along with others, had journeyed through the vast expanse of the galaxy, remaining isolated from the nests on Alderaan for thousands of years. This isolation ended when the nests detected the presence of Vector Hyllus, the Joiner and Dawn Herald of the Oroboro nest, who had departed Alderaan and was traveling with Cipher Nine. Killik flit ships followed the X-70B Phantom-class prototype that Vector was aboard, and Daizanna was the one who initiated communication with him. The Iesei were overjoyed to discover their long-lost brethren, and Daizanna extended an invitation to Vector to join their feast. Subsequently, Vector, who was also a member of the Imperial Diplomatic Service, sought to establish official ties between the Sith Empire and the Killiks. Daizanna was among the Killik representatives invited to participate, and despite sensing the humans' fear of the Killiks and the Joiners, she maintained hope that a peaceful agreement could be reached. Sadly, a xenophobic Imperial named Falner Oeth chose to undermine the peace negotiations by detonating a bomb during one of the meetings. Daizanna tragically died in the blast while selflessly protecting a Human ambassador and Oeth, who openly admitted his actions, exploited her death to deliver a pre-written speech denouncing the Killiks. However, due to Vector Hyllus's efforts, Oeth was captured, and formal diplomatic relations were successfully established between the Killik nests and the Sith Empire.
