The Lagonna travel in small merchant family bands called guri (singular "guros"). They most commonly trade with Meletis, which provides the biggest market for their wares, but they also do business with Setessa.
- Elder: The head of each guros is typically its Elder, the eldest member. The family head has the final say on all clan-related decisions.
- Barterer: Each guros has a barterer who serves as liaison between the guros and its trade clients. Barterers are, by necessity, more diplomatic and more knowledgeable of other cultures than the average centaur.
- Omener: The omener reads messages from the gods for the guros. These messages can be from an eagle flying overhead, a lightning-struck tree, a toad crushed on the roadway, and the like. The omener has knowledge of all of these "omen signs" as well as which god may have sent them.
- Courser: Coursers explore new trade territory for the guros. They may not be with the guros for long stretches, but their excellent tracking skills always enable them to find their group again in short order.
- Koletra: Every guros tries to travel with at least one of the Koletra—burly, well-trained warriors of the Lagonna Band. Not every guros has Koletra of its own, and guri share their best warriors among each other as a sign of goodwill and a way to forge bonds.
- Heptaristi: Once per year, a massive Lagonna herd is gathered and all guri attend. The Lagonna trade heavily among their own during this summit, but the highlight of the event is the choosing of the Heptaristi, the seven leaders. Seven guros elders are chosen to form the Heptaristi and to make all of the most important decisions for the band. The Lagonna treat this as if it was a democratic affair, but in truth, most seats are purchased through trade agreements with other clan leaders.
