Finnegas aka Flynn

A leprechaun and Sean's fairy godfather. A servant of the higher powers of Faerie, Flynn facilitated Sean's re-entrance into the mortal world by pretending to be fulfilling a debt to the warlock, Dominic (Daniel) O'Bannion. Flynn protected and guided Sean in the first few unsteady years of his time on Earth, and taught him a great deal, not only about the Faerie world, and the legends and myths of Old Europe, but also about magic, petty theft, and how to run a good con. He served for a time as a familiar to O'Bannion, and in that capacity, protected the boy from the warlock's more erratic fits and dangerous moods, while also assisting him with his own magic.

While Sean was in America, Flynn left O'Bannion's service, the time of his new duties drawing near, and allowed himself to be "caught" by the old priest, Father Donald "Donnie" Stephan O'Keeffe in Boston. Winkling a wish out of the reluctant leprechaun, the priest asked for him to "Make me see my brother again." A wish that the small fey was happy to oblige, as it would continue to shape the now dangerous young man and put him on the needed path.
