She wrote Janus instead of Magus because, as far as Kid and Serge's party are concerned, Magus is a "just" a Demon Warlock King from the Middle Ages who rose among the bloodthirsty Mystics and led a disastrous war against Guardia. "Janus", although unknown to Kid, is a less "WTF-ish" name...
I never really thought about it that way. Thanks Chrono99! I am hoping that "he" still is somewhere watching over Kid or searching for Schala. Though I never really calculated age for Magus. He should be in his late 30s to early 40s now, right?
For a Zealian, or someone of his stature, and from what RD said, he may be in his 30s, but not 30s as in human wise. Besides having royal blood and the power to change forms (well atleast change other peoples forms), and if what Chrono'99 said was true, then he probably may look younger anyway, with an air of nobility.
Personally, I don't think Magus looks that warped. He may be pale if he stays in that castle all day, or maybe hes got that illness with the sun or something. The red eyes may mean that they're bloodshot, and the ears could be normal for Zealians. I mean, they must have a trait of somekind. They do in themselves say that they are distanced apart from the Earthbound ones.
But if it came down to, as Chrono'99 said, a voluntary process, i'd come to two conclusion.
Magus had to do it for his position with the mystic and Ozzie, though I believe that Magus, even as Janus, was always stronger than Ozzie. And Magus just outright showed him off and Ozzie didn't torture him or any of that bullshit.
And my other conclusion would be that Magus doesn't seem like a type of person who'd change just for the mystics. Personally, he seems to me in comparison to them that hes above them, so he wouldn't care what they think. Aslong as he has power, they worship him.
So yeah, Like I said, I doubt his appearance comes down to his dark magic. It may be voluntary, or just his appearance brought on by his sorrow (like if hes gothic in nature, he stays inside and gets pale etc).
