An Evolutionary Myth by Bo-Young Kim, translated by Gord Sellar and Jihyun Park. First English publication in May 2015 issue of Clarkesworld.
Description, by Lois Tilton [Locus]: "Historical fantasy set in a fratricidal era of the Korean kingdom, with the universal theme that as the king does, so goes the kingdom. The current king does not do well at all, being a megalomaniac tyrant. The kingdom, accordingly, is afflicted by drought and the people are suffering, which puts them in hope of a hero come to deliver them. Our narrator happens to be a surviving son of the previous king, and he has good reason to suspect his tyrant uncle will seek his life. Seeking anonymity and concealment, he ruminates on the nature of evolution."
