Magic Fruit

The Magic Fruit is a fruit that grows on a small tree on an island in the Swamp, the death bogs of Tamir.

Background
In the middle of the joyous celebration welcoming the return of Prince Alexander and the rescue of Rosella, King Graham collapsed onto the throne room floor. To save her father from death, Rosella was offered the chance to go to Tamir where tehre grows a magic tree that bears but one fruit every one hundred years. The tree is hidden in a swamp within the Impossible Mountains. To reach the swamp, Rosella had to enter a waterfall, pass through a troll-infested cave, and cross a hidden abyss. Then she had to cross the deadly swamp and get by the king cobra that protected the fruit tree. One bite of the fruit cured her father and restroed his vigor.

Behind the scenes
In the Arabian Nights story of the three brothers attempting to win the hand of the same princess (see Magic Carpet), one of them discovers a magic fruit that cured sick people of most mortal diseases. One sniff was enough to do the job. The prince was able to save the princess's life with it, having been transported to the fruit on his brother's magic carpet.
