I'd like to ask about the meaning of the word "shephering" in the following context.
Because the second ticket promised him a small cabin onboard a methane-fueled ship that would leave for the New Isles two cycles later. Punctuality was his responsibility. If he was late, the ticket was worthless. And Jopale would be trapped in the Port with every other refugee, shepherding the last of his money while absorbing news from around the world.
Does "shepherding" here mean that Jopale will have to spend as little money as posible?
It means taking care of his money so that he will not run out.
