I think Baldur's Gate 1 and 2 give off similar vibes. 

I'm new to the game series, so pardon if this is something considered as common knowledge. I did try to browse the subforum for answers though couldn't find any.

I initially got the quest "Angevine in Exile" but when I confronted her, got another sidequest "Ahmed's Libram". If I refuse to follow what I was tasked to do, would that affect the ending or my moral standing in the game (if such a thing exists)? 

If I also steal or do other crimes, would it also impact the ending I got? 🤔 

Also when I finish the Avadon series, what series should I go for next? Geneforge? Queen's Wish? Is there a lore that connects all the series together? Should I be playing them in a certain order?
