You could say the same about demons in Elrios. It was only recently that I learned they weren't just in fairytales. Who knows, maybe your world's elves are just good at hiding?

[He can live with being called maybe-fictional, though. With that, Clamor finally relaxes. Maybe demons really are nice...?]

They say only the gods have true immortality... well, I wouldn't know much about that. Elves and spirits can live for hundreds of years, but they can still be killed like any mortal being.
