Basia was good friends with Praxidike Meng, a botanist who lived and worked on Ganymede with his daughter Mei. Mei and Basia's son Katoa shared the same immunodeficiency disorder, attended the same school, and were under the care of Dr. Strickland.
During the Ganymede incident, Basia's third child Katoa, who suffered from Myers-Skelton Premature Immunosenescence, was kidnapped to take part in human-protomolecule hybrid experiments. As the war on Ganymede intensified, Basia decided to cease the search for his son and escaped on the stolen Mao-Kwikowski Mercantile ship Barbapiccola. James Holden and Praxidike Meng later found Katoa's body in a covert lab on Ganymede.
After Basia and his family had lived on the Barbapiccola together with other Ganymede refugees for over a year, probe results started coming back from the first exploration of extra-solar planets on the other side of the newly reactivated ring system in the slow zone. The refugee ship travelled to the Ring and settled on the planet they called "Ilus" before anyone else could claim it.
When Royal Charter Energy received the charter for mining lithium on Ilus from the United Nations (who called the planet "New Terra"), Basia became part of a resistance and fought to keep the settlers' independence. He was one of the main perpetrators in the destruction of the landing pad that caused the RCE ship Edward Israel's shuttle to crash land, and also took part in the ambush attack that claimed the lives of five RCE security personnel.
After RCE security chief Murtry discovered he was involved in the resistance, he arrested him and placed him in UN mediator James Holden's custody. Since Basia had attempted to warn Holden of a resistance plot to assassinate him along with the RCE security, Holden instructed Naomi Nagata and Alex Kamal to treat Basia as a non-hostile in protective custody as they remain in orbit over the planet on the Rocinante.
