Moglin first appears in Chapter 1 of Treachery of the Gods, after Lightning clears the Sage's Path gateway, remarking she has the "smell" of KP on her. Moglin follows Lightning on the overworld map until she enters the next gateway, telling her about the moogle shops that collect a source of world energy known as Kupo, or KP, and offer items in exchange, and also remarking on the value of Rosetta Stones as they allow additional accessories slots to be purchased. He tells Lightning he's preparing to open a shop of his own, and asks her to drop by.
