The Sphinx is an unreal creature. It exists solely because it has been imagined. It is well known that in an infinite universe everything that can be imagined must exist somewhere, and since many of them are not things that ought to exist in a well-ordered space-time frame they get shoved into a side dimension. This may go some way to explaining the Sphinx’s chronic bad temper, although any creature created with the body of a lion, bosom of a woman and wings of an eagle has a serious identity crisis and doesn’t need much to make it angry.
