A spriggan is an ugly kind of faerie that always seems to be in a bad mood. (However, faerie emotions and morality sometimes don't match those of humans, so sometimes it is difficult to know how they feel.) Ordinarily they are tiny faeries that are small enough to hide under flowers and plants, but they can appear to grow very large to scare people. Their favorite thing to do is steal, and though they sometimes steal children and leave changelings, they prefer to steal possessions, especially jewels and prized treasure, and add it to their own, then guard it obsessively. They will destroy the gardens and property of anyone who tries to investigate the whereabouts of stolen belongings, and some say they are actually spirits of long-dead giant folk that used to roam the land before humans.
