The sylph believe the moon to have once been their home, and that its destruction was a punishment from Ybris, casting them from their celestial paradise to survive in the ash-eaten waste of Erj. The nature of the sylph’s transgression is unknown to them, and they work tirelessly to uncover artifacts from their cultural past in an effort to reacquaint themselves with their crime and, hopefully, achieve absolution, allowing them to return to the sky and forever leave Erj behind.

Few erjans understand or believe the sylph’s self-proclaimed Celestial Heritage, but then again, few can argue with the culture’s abundance of comparatively advanced technology.
