It makes sense in a way. I don't think these quotes are enough to explain to me what Refia is like, though. Which FF personalities do these characters mostly resemble? Luneth looks a bit like Sephiroth, Arc maybe reminds me of Edward based on your description (he's first "weak", but he eventually finds his strength), Ingus makes me think of Auron (the chivalry knight who still isn't the main character) and Refia reminds me of... I don't know, Penelo?
