Elvensang is a story about a young elf raised alone by his mother in a human world that regards elves with scorn and hostility. The setting is inspired by the early medieval period with low fantasy elements. It is a ruthless, everchanging place that constantly puts one’s morality to the test, and it will be up to you to decide whether the story plays out as a tender romantic drama or a descent into the depths of malice and depravity.‚Äč
