The Master of the Garden  is a mysterious entity tasked with preserving the knowledge of the ancient world within an isolated and concealed area referred to as "the Garden", an idyllic place containing plants and animals long extinct in the outside world, and samples of literature, music, and advanced sciences.
The Master, himself an engineered life-form, cures Nausicaä of her radiation poisoning and reveals to her the plan of the previous civilization: to purify the Earth of toxins using the genetically-engineered Sea of Decay, then use the old sciences and creatures contained within the Garden to rebuild the world. Though he attempts to persuade Nausicaä to remain in the Garden for the rest of her life, her conviction proves too strong and he permits her to leave.
