The Divine One...
But would we be stuck as playing the cannon one (Lucien) or would Larian allow us to create a name and even choose The Divine One's gender like in Divine Divinity? I guess players will have to ignore The Divine One's appearance in Divinity 2 as a male warrior called Lucien.
Larian could do something similar to Mass Effect where you can play Shepard as the default John Shepard with his unique appearance or create a custom character altogether.
This also raises the question...will the character be voiced? If the character is voiced, I hope it's akin to The Witcher, Deus Ex:HR and Two Worlds 2 where your characters says EXACTLY what the text says.
I have no problem with voiced protagonists so long as there's no paraphrase system.
