Ethereans are humanoids who have been touched by the misty, ghostly energy of the Ethereal Plane. Oftentimes, this partial conversion of one’s material form is caused by a surge of ethereal influence in their presence—perhaps from encountering an especially powerful spirit—or after having been exposed to the Border Ethereal for an inordinate amount of time, most typically as a result of being trapped there. However, some ethereans are indeed bestowed with this influence through their bloodline, such as via a fellow etherean parent, or by being born of a humanoid possessed by a ghost.
