|“||This is very unnerving, I know, but you must trust me. It is very important that you pack your possessions so that we may leave Candlekeep immediately. Hurry, for there is no time to tarry! The keep is well protected but not invulnerable.||”|
Gorion was a monk, a skilled spellcaster, a learned sage and a respected Harper. He lived in the library-fortress of Candlekeep during the times when he wasn't adventuring.
When you begin the game, you are told that Gorion is waiting to leave Candlekeep with you. You are instructed to gather some supplies and protection, then meet him at the steps of the Library.
Shortly after leaving you are ambushed (in a cutscene) by an "Armored Figure" that we later learn to be Sarevok, accompanied by Tamoko, two Ogres and two Thugs, one of which does some minor damage to you before Gorion tells you to hide and attempts to fight them off. Gorion is murdered in front of your eyes, and so ends the Baldur's Gate Prologue.
You then begin Chapter 1 of the game.
