Pixie (Wikipedia): "In traditional regional lore, they are generally benign, mischievous, short of stature and attractively childlike; they are fond of dancing and gather outdoors in huge numbers to dance, or sometimes wrestle, through the night... Pixies are said to reward consideration and punish neglect on the part of larger humans. By their presence they bring blessings to those who are fond of them.... They are also prone to...violent mood swings and temper tantrums.... Wildly rambunctious tricksters...."
Oh bless me, I'm running a halfway house for the fae! Somebody get me a rowan branch!
