Would just like to point out the errors in the walkthrough so others won't be confused in the future. It seems most of it was copied from BG, but some stuff wasn't added.
One of the most important errors I've noticed is that Neera is not mentioned once so ever on the Beregost map. Should probably add the encounter with her there.
Edit:
More errors: You do lose rep if you kill Marl in Beregost after choosing the good path.
You do lose rep if you kill the FF mercenary south of Beregost as well. It's best to chose options 1-3 when talking to him.
Simmeon is mentioned in Wyrm's Crossing, but a number 6 was never placed on the map to his whereabouts.
