The Swamp of Sadness is a deadly swamp that symbolically represents pure sorrow and misery, and is an early location in Fantasia in The Neverending Story.
It is where Morla, the Ancient One, a giant turtle, lives and informs Atreyu of the remaining distance for his journey to reach the Southern Oracle, ten thousand miles away.
Legends say that whoever lets despair overtake him or her will sink into the swamp.
Artax, Atreyu's horse, was the swamp's most unfortunate victim. Grieving, and barely able to go on, Falkor the luckdragon saves Atreyu from the swamp just as Gmork, the Nothing's evil wolf-like servant, is about to kill him.
The Nothing devours all of Fantasia, save for a single grain of sand and the Childlike Empress. Bastian uses his imagination to restore Fantasia to its former glory, and Atreyu is seen riding Artax across his homeland in the Grassy Plains. The Swamp of Sadness is not seen again in the new Fantasia.
- It is also referred to as the "Swamps of Sadness" (as mentioned by Gmork).
