#29 The Pooka
No fairy is more feared in Ireland than the pooka. This may be because it is always out and about after nightfall, creating harm and mischief, and because it can assume a variety of terrifying forms.
The guise in which it most often appears, however, is that of a sleek, dark horse with sulphurous yellow eyes and a long wild mane. In this form, it roams large areas of countryside at night, tearing down fences and gates, scattering livestock in terror, trampling crops and generally doing damage around remote farms.
The pooka has the power of human speech, and it has been known to stop in front of certain houses and call out the names of those it wants to take upon its midnight dashes. If that person refuses, the pooka will vandalize their property because it is a very vindictive fairy.
