During a trip to Gabon, a group of uninitiated lambda people will attend a traditional initiation ceremony and one of them will be transported to a mysterious world thanks to the hallucinogenic capacities of a plant called IBOGA. This species is rich in indolo-monoterpene alkaloids, the main one being ibogaine. It is used in traditional medicine in Gabon to produce, by chewing the root or bark, hallucinations and near-death experiences. At too high a dose, the plant can be fatal.
The hero of the story is an average person. Once entering the mysterious world, she takes on the appearance of a pygmy, (the pygmy peoples are ethnic groups whose average height is exceptionally short and live in the forest in equatorial Africa).
The hero is immersed in an imaginary universe and as the adventure progresses, his escape will turn into a quest for knowledge.
