The quest was to be given once the Vault Dweller had gained the trust of the S'Lanter. Rinar would ask the Vault Dweller to make contact with a nearby human settlement, and ask them to begin trading with the Burrows. The Vault Dweller could potentially go to the Hub, Junktown or The Khans.
Junktown wouldn't trade with the Burrows, if he chooses to go there first. Upon going to the Hub, a caravan would be sent to the Burrows to trade, and the player character would be rewarded for finding a new customer. However, going to the Khans would result in them sending an invasion force to destroy the Burrows, resulting in it becoming a ruin, and all of the survivors turning hostile.
