The Silver Thread is a visible silver thread that every civilized Wolperting can see in their mind. Young civilized Wolpertings use this to find their way to the city Wolperting, because all Silver Threads lead to this city. A Silver Thread to a Wolperting also leads to the person they are meant to be with. For Rumo of Zamonia, the Silver Thread was flowing back and forth between him and Rala of the Forest. This does not necessarily mean that it will work out. For Ushan DeLucca, his first wife divorced him because of his extreme mood swings that are tied to weather conditions.
