The Orchard of Duir is one of the ancient Green shrines scattered throughout the land. It was one of the stops on Giraldus and Tysle's pilgrimage to Greenreach. Ysabelle and Vesper also accompanied them there.
It was in the Orchard of Duir that the Green was said to have planted seven trees before winter came. Duir carved inscriptions into a marker at the entrance of the sacred orchard, though time weathered them to the point where they were unreadable.
When ice finally overcame the Green's defences, He took shelter in an oak tree in the orchard. It was this same oak tree where Ysabelle, Vespertilio, Giraldus, and Tysle rested on their stop there, and in which Ysabelle conversed with the Green.
