They should show more about the history of the guild, now that you mention that point the unknown guy looks like silver, so he would be above 100 years old..the question is how did he get messed up with zeref and then he is not originally a demon from the book of zeref, because that would have happened 400 years ago....what is the relation between zeref and Mavis...
