Backstory: Leader of the evil leprechauns, Nilremo was a powerful wizard who turned his magical knowledge towards evil purpose. Unlike the other leprechauns which sought to bring joy and laughter to mankind and enjoy the occasional prank at their expense, Nilremo and his evil leprechauns wished to spread dismay and despair. Robbing mankind of what it treasured to keep for themselves.
In order to accomplish this dire task and well aware that the other leprechauns were well versed in magic, Nilremo got his hands on a science powered shrink ray. Cutting through their magical defenses with something they never could have thought to develop a defense against.
Once he successfully captures his more good natured kin, Nilremo would have nothing to stop his criminal efforts.
