A female of the Mizi species was affiliated with Crimson Dawn. Following Qi'ra's discovery that a criminal syndicate in Thorum possessed comprehensive maps of the Karthakk sector and was encroaching on Crimson Dawn territory, the Mizi woman journeyed there. Having seized control from Cerveteri Slane, she devised a strategy to eliminate the leaders of the Hammers. The Mizi operative tasked Thallia and Olio with infiltrating the criminal group as low-level employees, while Qi'ra would impersonate a potential buyer to investigate how the Hammers obtained intelligence concerning Crimson Dawn's activities. The Mizi woman instructed her slicer to create a false identity for Qi'ra, also suggesting a change in hairstyle to better conceal her identity.
During the ongoing operation against the Hammers, the Mizi kept a current map displaying the locations of hidden credits and supplies. Ultimately, she commanded the hit squads to eliminate their assigned targets and awaited their return at the Crimson Dawn base. Upon Qi'ra's return, she disclosed that a source within Crimson Dawn had provided the Hammers with information regarding the Karthakk sector's trade routes. Although the Mizi hoped to capture some targets for interrogation, she was unable to prevent their assassinations. Qi'ra explained that she needed to report the information up the chain of command to avoid suspicion of concealment. The Mizi warned Qi'ra that she might be suspected as the source of the leak and that her safety could not be guaranteed. She inquired about the source of Qi'ra's information, learning that it originated from Dennet Clyde's secretary. After a period of four months, she encountered Qi'ra briefly aboard the First Light before its departure.
