Who were Wee Folk?

Wee folk refers to fairies and their kind. Medieval theologians suggest that wee folk may be a special group of demoted angels, spirits of the dead or fallen angels. Ancient texts say the entities are of a middle nature, i.e., between humans and angels, and that they can inter-marry with humans and bear half-human children. The consistent factor in all legends is that wee folk constantly meddle in the matters of humans – to do good or sometimes evil.
