It is I, Magical Moogle, wishing you the happiest of holidays! We will be beginning our Starlight Celebration right now!
Unfortunately the festive moogles have been so busy putting up decorations, they haven't had time to hand out their starlight cards. As a result, they would be very appriciative of you, the adventurer, passing the cards out for the festive moogles.
You can find a festive moogle in Port Bastok, Windurst Walls, Port San'doria, and even Jueno!
P.S. I talked to the big man, and he said he'll turn on empress/emperor bands until the 26th due to recent issues, so get that XP while the XP is good to get!
