The novel opens with Santiago, a shepherd content with his simple life, who is unsettled by a recurring dream pointing toward treasure near the Egyptian pyramids — and an encounter with a mysterious old king, Melchizedek, who urges him to pursue it.

Key ideas established in the opening:

• Melchizedek introduces the novel's central concept: a "Personal Legend" — the unique life purpose each person is meant to fulfill, which most people abandon in favor of safety and routine
• The old king argues that the universe conspires to help those pursuing their Personal Legend, a principle that recurs and is tested throughout the rest of the novel
• Santiago's decision to sell his flock and pursue the dream despite having no concrete plan establishes the novel's central tension between comfortable stability and uncertain purpose

This opening establishes the fable's guiding philosophy before sending Santiago into the literal and symbolic journey that tests it.
