The First Well is the first well ever created. They say it was made by The Maker himself. It has great healing power, and could extend a person's life by epochs, as shown by Ouster Will. When Yurgen and the other dragons were burrowing through the ground, the well disappeared. It was found again by Artham Wingfeather when he left Castle Throg after being melded. He saved some of the water and used it on Nugget, and later on Podo Helmer. In book four, although we never see it, Oood the Troll uses some of the water to heal himself after being wounded by the Cloven. At the end of book four, we see Sara Cobbler and the Wingfeathers boarding Hulwen in hopes of finding the First Well somewhere in the Blackwood to heal Janner Wingfeather.
