Following his departure from Legado, the narrator finds himself in the bustling port of Maldonada, seeking passage back to Europe via the island of Lugnag. However, fate intervenes when he discovers that no ships are currently bound for his intended destination. Acting on the advice of a "noble gentleman," the narrator decides to visit the nearby island of Glubdubdrib, located approximately five leagues to the southwest. This detour marks the beginning of an extraordinary encounter with the supernatural.
Upon arrival, the narrator learns that the name "Glubdubdrib" translates to the "island of sorcerers or magicians." This small territory is governed by a powerful leader who commands a tribe of sorcerers. The governor possesses a remarkable, albeit unsettling, ability: through his "skill in sorcery," he can summon individuals from the dead to serve him for a period of twenty-four hours. This power is subject to strict constraints, as he cannot summon the same person twice within a three-month period unless "very unusual circumstances" arise.
The narrator’s initial entry into the palace is marked by a profound sense of dread. He describes passing through rows of guards whose appearance caused his "flesh to creep with a horror I cannot express." Upon reaching the main chamber, he witnesses the governor’s absolute authority over his attendants. With a simple "turn of the finger," the governor makes his servants disappear "in an instant, like visions in a dream." While this display initially shocks the narrator, he soon acclimates to the environment. Within a few days, his initial terror is replaced by "a great curiosity," allowing him to interact with the spirits without fear.
The governor grants the narrator an extraordinary privilege: the freedom to "summon the spirits of whomever I chose" and to ask them any questions, with the assurance that the spirits would answer "truthfully, as lying was a talent of no use in the lower world." The narrator takes full advantage of this unique opportunity to converse with legendary historical figures.
Among his notable summons were Alexander the Great, Julius Caesar, and Brutus. The narrator expresses a particular fascination with observing the interactions between these figures, noting with "much pleasure" that Caesar and Brutus appeared to be on "good terms" in the afterlife. The narrator reflects on his experience, stating that he primarily "fed my eyes with the destroyers of tyrants and the restorers of freedom to injured countries." He concludes his account by noting the profound "satisfaction" he derived from these spectral visitations, finding the historical insights far more compelling than the mundane concerns of his own time.
