There's a strange confusion with Character Sheets.
Where he's a courtesan, and not a charlatan as he is now.
I made a mistake, my bad.
The artbook is from Digital Deluxe Artbook EA's time, but with clothes and new art as in the game - which confused me. So we can't 100% about its corrupted past and what it was inspired by - WHAT A WASTE. No wonder the fandom is on fire and everyone understands it differently. And considering we have the upper city gone (it was supposed to be) - we can't take in Astarion's story entirely in the game.
Oh my goodness what a mess.
Also, Stephen Rooney said that Astarion was changed the least than other characters. I heard that, didn't mention it because I don't know the exact source, maybe it's from this
link interview.
Only if someone someday adds information about his dark past in the dustiest corner of Cazador's castle. That's the only way we'll be sure. Or a new book, artbook, fanbook, something.
If someone painting a landscape, thay not going to start abruptly painting a still-life. The author's idea that this elf was Very Not Good remains.
Makes sense - because if he's so very lambish, not a complex character with evil in his blood (While we have Minthara), that we'll decide what to do with. We're just not going to have an evil-male-character-companion in the game.
