When a crew member truly hopes in their heart to encounter someone, "Silver" will ensure they never do; whenever a crew member wishes to see a certain place once more, "Silver" will never sail past that place.
As long as they remain on the ship... they are destined to brush past the people they want to see and the places they want to visit.
This is the Curse Binding known as "A Hair's Breadth From the Ends of the Earth."
But if used in reverse, it can also serve as a sanctuary.
For instance, Arthur truly wishes to become a Gold-rank, to return to his family and take power—then the power of "Silver" will keep him forever away from his kin;
The centaur Lucia wishes to find her own kind, to return to the centaurs' retreat, then as long as she is on "Silver," she will never encounter any centaur, nor will she ever enter the centaurs' hidden abode.
When a person harbors some kind of "impulsive desire" within, Silver ensures they will never have the opportunity to fulfill it.
