Uqbar
Uqbar is a fictional place in Jorge Luis Borges's 1940 short story "Tlön, Uqbar, Orbis Tertius". Uqbar in the story is doubly fictional: even within the world of the story it turns out to be a fictional place. The story turns on the narrator's discovery of a fictitious entry about Uqbar: that is, a false article in an otherwise legitimate reference work. Also, despite its overall fictional nature, "Tlön, Uqbar, Orbis Tertius" is loaded with references to real people and places and it playfully combines reality and fiction.
