Fantasy is not the opposite of reality; it is what reality forecloses, and, as a result, it defines the limits of reality, constituting it as its constitutive outside. The critical promise of fantasy, when and where it exists, is to challenge the contingent limits of what will and will not be called reality. Fantasy is what allows us to imagine ourselves and others otherwise; it establishes the possible in excess of the real; it points elsewhere, and when it is embodied, it brings the elsewhere home.

In a semi-relevant note: In the theme of this blog discussing the actual variance of people in Europe, there is a comic called Thistil Mistil Kistil that does have a diverse cast and is a good fictional example of the traveling that did occur. It has some mythology present in it, so it's not clearly historically defined, but I thought it would be something worth pointing out. — Asked by tealtype
