Bug?

[็]

Yo,I gave the book to Andreas but I can't buy it from him, from what I understand you should advance a little in the story but since I arrived in Upper Calrath I don't think it's a problem, I need to buy from him Pilgrims Keys..Suggestions/opinions?

[Suwako]

The pilgrim key is dropped by the Fidelis captain in skyrest after you go enough through the game or you can buy it off of him before that point. I dont know the exact when this happens.
