Manannán mac Lir is most likely to be found in the Otherworld—more specifically, on his home island of Man. He was the first king of the Island of Man and is still royalty there, where he's usually out cruising the waves in his chariot or magic boat. One problem: because he's a shape-shifter, Manny might be in another form, so be sure to check everyone around you if you're looking for him.
