Once again you correct me, but that's OK. I should've seen it comming, but I'm not thinking too clearly.
And 'Lunatic' comes from 'Luna' whitch means 'moon' so I'm not really wrong, now am I. And all european languages have the same origin Latin if you go back far enough. And american is too, since it originates from europe (you often hear 'gesundheit' in series whitch, as you probably know, is German).

However in FFVIII mosters fall from the moon, so the translation could also be 'Answer/Truth from the moon'.
