Eder Delin shares many characteristics with Eder Kemo, such as its lamps and statues; however, the Age itself contains a very different collection of plant life. It is forested, with tall deciduous trees shading the ground below. The air is foggy, and the Age's sun tints everything with a pinkish-orange hue.
Eder Delin also has a bahro door, similar to those in the Ages of Yeesha's Journey. This door is emblazoned with a different symbol, and is identical to the one found in Eder Tsogahl. A series of seven journey cloths scattered around the Age are used to activate various segments of the door's locking mechanism. This lock requires all of the cloths to be activated in a unique sequence each time the unlocking mechanism is triggered. The placement of cloths and the randomness of the activation sequence means that it takes multiple explorers to complete the unlocking sequence in the allotted time. Seven explorers is ideal, but experienced groups have been able to complete the process with fewer participants.
Eder Delin was the first new Age approved by the DRC to be released since the restarting of the restoration process. Marie Sutherland spent much of her time there in late 2005. The Age was first shown to explorers during the DRC liaisons's first meeting with the DRC in 2006, where an image of it was spotted on the neighborhood imager. On January 19, 2007, it was first given out to a small percentage of neighborhoods but later that day appeared in all neighborhoods, with the DRC apologizing for their ill-advised decision to release the Age to limited areas.
From February 20th to April 5th, 2007, Eder Delin experienced a sunned-onset winter storm which blanketed the Age in a layer of snow. The storm had been predicted by the DRC several days earlier. A second winter season began on September 10th, 2007, and lasted for over 6 months, ending on March 6th, 2008. This winter season, unlike the first, was not predicted by the DRC.
