Eder Delin is a garden age, and an age of rest - much like the ages of Eder Kemo, Eder Gira and Eder Tsogal. The age has a naturally autumnal feel, though weather conditions can quickly change, leaving the age covered in a fine coating of snow. Not much is known about the history of Eder Delin though it was probably written during the D'ni 'Garden Binge'. It was the first new Age released by the new DRC and placed in some of the Bevin neighbourhoods for explorers to explore.
The floor and walls of the small canyon accessible in this age consist of a rough grey type of rock. One of the more noticeable features of the landscape is the curious way in which the canyon walls have been shaped to form strange arches, similar to but more extreme than the canyon in Eder Kemo and Eder Gira. The Age is situated in a dense forest of huge trees and smaller plantlife. The sky is not visible due to a thick fog in the upper reaches of the trees. There is no discernable day-night cycle. Another strange phenomenon in this Age is the sudden change from an autumn-like climate to a snowcovered winter state, not only does this happen rather quickly, but it creates a vast change in wildlife. Each weather condition brings it's own variety of animals, including several species of birds.
