Fernehalwes: Rumor has it that all of the gear shown here is actually in the game! Which would mean that bookish beauty in the mortar board on the far right is...!!!

Well i thought at first that it was Arcanist but i changed my mind reading all posts about that. I think it's really Scholar

- Hiiii i'm pleased ! -

Ahem, what makes me so happy is this sentence made by Fernehalwes. If it was Arcanist on this wallpaper, why being so secret about it ? We know about the Arcanist so there's no secret to keep to say that the elezen with the book is Arcanist. But no, Fernehalwes remained very evasive.

I really think it's Scholar (and hope so )
