In the interest of presenting a complete set of facts I will also mention that Otik2 changed his version of events a number of times. He seemed annoyed by my questions and by this website.
According to an active member of the FF3 community at the time the rumor first surfaced: "... I went by Purgatory for a bit on a few FF boards, but Spatvark's the nick I use everywhere, including FFO, though that wasn't where I first heard the rumour.
That was on Eyes on Final Fantasy, from one of two fellows: BOU (Big Ogre Umaro) or Kawaii Ryûkishii, neither of whom I think are Claudius Aquilla."
Food for thought.
