The BoG is gained from the quest "Ancient Treasure." Use the BoG to check on your girls' Affection level, if they're pregnant, are they horny today, etc. This quest can be started very early in the game but takes a few days to complete.
- After you've spoken to the innkeeper in WW the first time, the next time you go there a shady guy with an eyepatch tries to sell you something (300 coins). Buy it, ask the innkeeper about it, then ask the blacksmith about it.
- Get Uncle George's key from the cemetery. Warning, since you did Waystones ghouls should be out even during the day...unless you've also progressed the vampires storyline to where the undead don't bother you any more...
- Retrieve the book from the right-side building
in front of the Ancient Shrine entrance. Not inside the Shrine itself, not the smaller stone things. The entrance to it is hidden, on the side facing the wall.
- Take the book to Erevi and ask her about it.
For the dress go to Edgar after completing the Waystones quest, buy the Oriental Dress, and give it to ED.
