Garvan Spasso operated as an illicit merchant on the world of Kalab.
Garvan Spasso worked alongside Borke Valkanhayn as a business associate. Following an incident, Valkanhayn had to escape to Glova, where he kept doing business with Spasso. Not long after the Battle of Endor, Garvan Spasso contracted a team of smugglers to transport certain spices and holotapes to Borke Valkanhayn, who was then located on Glova.
