The only reason I bring this inconsistancy up is because I'm brainstorming for one of my projects that I've been neglecting down in the Fan Fiction forum, and I'd like some outside input.
So, I finished up the Original Saga today. As the main plot dictates the main character must return to Candlekeep to track down the Iron Throne leaders. Normally I just encounter Rieltar in the Library and get arrested not long afterwards, but for once actually ascended the Library floors and up to Gorion's room.
Gorion, in case of his death, left a letter in his room explaining your heritage and history with him. You're officially revealed as a Child, and Gorion explains that he took you from your mother whom was forced upon by Bhaal. He had been romantically involved with your mother and felt obligated to raise you as his child when she died in childbirth.
In Throne of Bhaal, however, the Solar tells us that our mother was actually a priestess of Bhaal whom Gorion slayed just before you were slaughtered to ressurect the dead god. The Harpers were forced back, and Gorion took you and fled from the scene before you came to any harm.
So, what do we think? Was Gorion, even in death, lying to you in his first letter? Maybe a simple mistake by the writers, or just that the story was changed around to add some drama before the end of the saga? And which way do you think it should have been?
