Their story
A legend tells that young Flannan was sent to grind corn at the mill one night without a light. A boy sent to check on him peeped through the keyhole and saw him grinding by flames shooting from his own fingers.
A stork then flew at the boy and swallowed his eye. Hearing his cries, Flannan ran out, made the bird give the eye back, and put it in its place again. The whole tale is legend.
