At the tail end of a twelve-hour tour beginning and ending in Dublin with stops at Belfast and Giant's Causeway in Northern Ireland, I was wiped and nodding off when our tour guide livened the tail end of the trip with an expository on Irish folklore. She pointed to a lone tree in a field and commenced to exposing a nuanced part of Irish history, some deridingly refer to as folklore, rife with potential danger to us listeners should we not heed her warning. A fan of mythology, I was intrigued.
