Hm, if you say it... I still had the impression that they would stick to the Zandalor's story which they wrote down almost a year ago (https://www.kickstarter.com/projects/larianstudios/divinity-original-sin/posts/443345) But I admit, I wasn't very carefully reading the dialogs and books in the alpha (in order not to spoil myself to much)...
We could always ask Macbeth to confirm it, but I'm pretty sure that they changed the story. (Larian is great at dialogue and character, but less so at making an overall plot and story.)
