The Lasarla fruit grows on most Trees of Wisdom and is the major contributing factor to the myth surrounding the trees. It is said that if a person eats the fruit, he receives wisdom beyond his years.
Whether this has any basis in fact has never been proven, due to the traditional taboo relating to research on Selab trees during the Age of Queen-Mothers. During the Phoenix Age and Golden Age, all cultural institutions decided to respect the traditional view of the trees.
