Olio was a member of the species homo sapiens (human) and an employee of the criminal syndicate known as Crimson Dawn.
When Crimson Dawn was planning their strategy for dealing with the Hammers, Olio voiced his worry that the Hammers had more members than Crimson Dawn did on Thorum. He and Myem were assigned the mission of neutralizing the security officers at the guard post and control room. After the successful robbery, the decision was made to send the Hammers a warning about operating within Crimson Dawn's domain. Olio's assignment was to infiltrate the Hammers as a new, low-ranking member and monitor a specific list of individuals. To facilitate recruitment, he and Thallia pretended to be a newly married couple. He, along with the rest of the Thorum team, went back to the First Light to receive training. During this period, his resentment towards Qi'ra grew because she did not step in when Thallia was falsely accused of sharing Crimson Dawn secrets with rival criminal groups, which led to Thallia's execution. Qi'ra, recognizing Olio as a potential danger, set him up. Dryden Vos executed him by launching his petar through Olio's eye, penetrating his brain, resulting in immediate death.
