Arixenos are little fire spirits that wander around, often claiming that they're looking for something and got lost. They're either blue, white, or orange, and generally have a bit of a childish voice. It's often believed that they're spirits of children who died while in search of something. They're relatively friendly and literally all are harmless, although some will occasionally be a bit rude. None can actually harm anyone unless they're threatened, in which they'll emit fire sparks that burn to the touch and can set things on fire. Otherwise, they can't really do anything.
