Hello Wilsio
I'm sorry if this confused you, but actually when you get the Ticket to get access to SS. Anne in Vermilion, this item doesn't appear in your Bag, it's a variable related to your account. Once you helped Bill to find his book, consider that you've done with this quest and you can continue up to Vermilion.
If you need further assistance with anything else, feel free to ask :Sing:
