To primitives, nuts and medicinal herbs aren't anything special, but the caravan is willing to trade grain for them.
Because it's easy for the caravan to make the trip, they won't demand an exorbitant price during the exchange.
What the primitives lack is a stable life. Grains can be stored for a longer time, helping them through difficult periods, and with just some daily gathering work on the island, they can support themselves through trade.
Their living conditions would be quite nice.
There are about a thousand primitives here. Their lives will leap forward, both materially and spiritually. The temple system ensures that they are all happy to help each other and maintain friendships, while the island's resources allow them to earn a decent income from commercial activities.
Seeing this situation truly brings joy from the bottom of one's heart.
However, the primitives are not as interested in the newfound wealth as they are in the Sand Dog temple system.
