The Ruins of Ravenwind [41, 12] are the remains of ancient Kaldorei civilization in northern Feralas, specifically the Highborne (much like Dire Maul). It is currently overrun with Northspring Harpies.
Shay Leafrunner, a rather absent-minded young Night Elf girl, can also be found here. She can be escorted back to her guardian friend, Rockbiter, a mountain giant to the south of the ruins. (Rockbiter is a reference to Never Ending Story. A reference that becomes even more obvious when you read the quest dialog)
There are also a group of Jaedemir dragons near the ruins, who are bent on protecting the large tree located at the center. These dragons make it very difficult for lower level characters to complete the Feathermoon quest, unless they stick to the pond while looking for the flames. If you must travel into that area, the dragonkin will not persue players swimming in the lake, even if previously aggroed. Players more familiar with the quest will know where the flames are right away, avoiding the dragons altogether.
