I finally read Vortex's post about the Count of Monte Cristo and found out that his real name is Edmond Dantès. If I'm not mistaken, the guy from Devil May Cry is also named Dante... or something like that, right? (see Gilch's post).
Basically, that's all for now. I haven't found anything else yet.
