Behind Setne stands the historical Khaemwaset, the fourth son of Ramesses II and a prominent priest of Ptah. His mother was Isetnofret. The prince's religious work connected him with Memphis, the burial of sacred Apis bulls and the old royal monuments of the Memphite region. The name Setne is associated with the priestly title setem or sem, rather than being a separate throne name. Khaemwaset became an heir late in his father's long reign but died before he could become king. That historical career is distinct from the supernatural actions attributed to Setne by much later authors.

Khaemwaset left inscriptions on ancient pyramids, preserving the names of their builders alongside his own and his father's. His activity has earned him the modern nickname 'the first Egyptologist', but it should not be mistaken for modern archaeological research. Scholars debate how much physical restoration accompanied the inscriptions and how the work related to the reuse of older stone and the maintenance of royal cults. The surviving record supports a Ramesside engagement with Egypt's past, not the claim that one prince invented every later practice of conservation. The combination of priesthood, writing and ancient monuments nevertheless offered fertile material for storytellers.

The First Tale of Setne Khamwas takes that interest into a dangerous tomb. Setne seeks the Book of Thoth, kept with the dead prince Naneferkaptah. Before he takes it, the spirit of Ahwere, Naneferkaptah's wife, describes how the book brought death to her husband, herself and their son Merib. Setne refuses the warning. Naneferkaptah challenges him to a board game and repeatedly defeats him, magically sinking him into the ground. Rescued with sacred amulets and books brought by his companion, Setne still carries the coveted text away.

His apparent victory becomes a lesson in loss. An encounter with Tabubu draws him into an illusion in which he agrees to sacrifice his property and family for his desire. When the deception ends, the children are alive, but his judgement has been exposed. He returns the book and fulfils Naneferkaptah's request to bring the bodies of Ahwere and Merib from their burial at Coptos to join him in the Memphite tomb. Restitution, rather than the theft of a more powerful spell, resolves the story.

The Second Tale first overturns another of Setne's assumptions. Seeing a splendid funeral and a poor burial, he expects wealth to secure the better afterlife. His son Si-Osire shows him that judgement depends on deeds: the poor man is honoured near Osiris, while the rich wrongdoer is punished. Later, at the court of the pharaoh identified with Ramesses II, a Nubian challenger demands that a sealed document be read without opening it. Si-Osire succeeds and reveals a conflict from an earlier age. He is a returned magician who has been born to defeat the old opponent. The son becomes his father's teacher as well as Egypt's defender.

These are literary adventures, not accounts of events witnessed by the historical prince. The first tale survives in the Ptolemaic manuscript Cairo CG 30646; the second is preserved in British Museum EA 10822, associated with the Roman period. Their remembered royal settings belong to the stories' construction of the past. In particular, the Mernebptah named as Naneferkaptah's father should not automatically be treated as the historical Merneptah, and the second tale's court should not be reassigned to him. Distinguishing these identities keeps the stories understandable without turning fictional genealogy into historical evidence.

Setne's appeal lies partly in the gap between expertise and wisdom. He knows how to read, perform rites and seek out hidden writings, yet he must learn when a warning deserves to be heard. The tales also allow other voices to correct him: a bereaved woman explains the cost of the book, and a child sees more clearly than an accomplished father. His adventures preserve a world in which the dead can make claims upon the living and learning carries obligations. The historical prince's memory is present, but the character belongs to the craft and imagination of later Egyptian literature.
