I'm pretty sure Dian is the fairy queen reincarnated. Bazel notices so many similarities between her and the Selene he knew because they are the same person just reborn. They have the same mannerisms personality looks and they say the same things that give him flashbacks of the past. Hope that helps!

If Dian is a reincarnation of the Dian that the Lord Margrave knows, it is also possible that the guy lady Selene is supposed to get married to is they guy with blond hair (is his name Helios?)
