Stories

Mateo Cárdenas, once known as Harry Potter, has no memory of his life before the jungle. As a toddler, he survived the plane crash that claimed his family, only to be found days later by Jonas and Izzy, who adopted him on December 1st, 1982. Raised deep in an isolated rainforest, Mateo grew up far from the wizarding world, learning to survive with his new family of explorers, retired pilots, and archaeologists. He became skilled in piloting, tracking, and uncovering hidden ruins, traversing grasslands, rugged mountains, wetlands, and even the harsh desert alongside his adoptive family. When Mateo was six, Jonas’s group first encountered Severus Snape. The wizard had entered the jungle on a secret mission, but his true purpose remained unknown. Lost and weakened after days in the treacherous rainforest, Snape stumbled upon Jonas’s camp. Though cautious, the family cared for him while he recovered. Snape observed Mateo closely, recognizing a familiar strength and resilience—but the truth of his identity remained hidden. Though his visits were rare, they left a lasting impression on the family.

 

Years later, Snape returned with a mission. The wizarding world was at war, and he sought Mateo, aware of the extraordinary abilities that lay dormant within the child once called Harry Potter. Mateo, however, had only ever known the jungle, his family, and the life they built. Reluctantly, he left for Hogwarts, but he never accepted the magical legacy thrust upon him. Magic felt foreign, unnecessary, and irrelevant compared to the life he loved and the people he swore to protect.  At Hogwarts, Mateo resists the world of wands, prophecies, and a legacy he never asked for. His heart remains in the jungle, where survival, loyalty, and family are the only rules he knows. The wizarding world may try to claim him, but Mateo will remain Mateo Cárdenas, protector of the only life he has ever truly lived.
