It's St Patrick's Day, Irish Pub - Feegles. (AKA the Wee Free Men, of Sir Terry's Discworld.) -- Anon Guest
Up the airy mountain,
Down the rushy glen,
We daren’t go a-hunting
For fear of little men; -- William Allingham, The Fairies
Britain has an Agency for everything. National Health, Child Welfare, Disability Assistance, you name it, they have it. They're also the home headquarters of UNIT and WHO, the United Nations International Taskforce and the Weird Happenings Organisation, respectively. And a good thing, too, since the British Isles seem to be ground zero for all kinds of strangeness. Up to and including a slightly crazed individual in a blue box.
Today, it's an otherwise normal pub somewhere in Ireland, and a problem that can't be solved with Five Rounds Rapid. A high-class phantasmal incursion from another realm. The beings from a different reality were Nac Mac Feegle, or 'Feegles' for short. All because the British Isles were a nexus of psychic energies. And a very popular fantasy author was causing a mental focus on his works and all the strange creatures within them.
