Military action
The small scale conflict that would begin when the appearance local armed militias sparked an incident with the forcibly displaced Fey Folk.
When the veil between realms was sundered, local militias were formed to investigate. The appearance of armed forces startled the already scared and confused Fey immigrants, who took up arms in self defense. This small scale confrontation was thankfully low with regards to loss of life, but would take the intervention of one Breaitheamha Ó Dufaigh to bring the conflict to a close.
