From the Lodestone forums:
Greetings, fellow adventurers!
In the last letter from the producer, Yoshida has mentioned about "Dark Moogle Battle (name tentative)" and we are sure that many of you are psyched to hear more about it. Today, we have some news for you. The name "Dark Moogle Battle" has been changed and it will be called "Good King Moggle Mog XII"!
Read on for the video, then discuss this in the ZAM Forums!
Yes, Moggle Mog XII, the "Good King", is what you will face next. We are sure that many of you are having lots of questions in your mind right now but please wait until the details are revealed in the upcoming topics. For today, we would like to give you a sneakpeek on the loots that "Good King Moggle Mog XII" will bring!
Also just to note that the adjustment has been made to the video thumbnail so that the weapons won't be shown. So the choice on whether to watch this sneakpeek or wait until they become your possession is all up to you.
