The party spent a week in Waterdeep, during which time Ranger Rick was arrested for drunk and disorderly conduct.
Lawrence de la Torrence caught Tief rifling through his things. He called a meeting of the entire party and Tief said that he was attempting to steal the Siren’s Amulet and The Guantlet of Necrodeimus because he did not trust Lawrence with them. He intended to give them to The Harpers. After a discussion the group agreed that the items should be placed in the hands of The Harpers and they all promised to be much more transparent about their intentions.
They arrived at the headquarters of the Harpers to meet Elminster Aumar who had arrived to examine the Grimoire. They also met Hershel Goldberg, an initiate of the Harpers, who aided them on their quest.
After a brief examination Elminster confirmed that the Grimoire is the genuine article – a book that is rumored to contain "all of reality" within it's pages. He did not open the book, though, because, he cautioned, "I do not know what will happen, and whatever does, I will be powerless to stop it." He was intent, though, on learning the full extent of the danger the book posed. When Nuadre mentioned a letter she carried from a fellow student that was murdered that pointed to some pertinent piece of information being housed in a library in Waterdeep it gave Elminster the idea to use Oromund’s Bookstand to examine the Grimoire.
When the party mentioned Womai Elminster dispatched Cami and Crystal Palantir to the East to investigate.
They went to Denier's Library and found the bookstand and proceeded to enter a book of fairytales, as well as a notebook containing stories that Nuadre had written, in order to test the limits and merits of the bookstand before introducing the powerful Grimoire.
During their experiments Nuadre revealed that she possessed a card from Vayne Hall’s Deck that was made from a page of the Grimoire. Elminster became erratic and attempted to snatch the card away from her but when he touched it he disappeared.
Confused and frightened the party returned to the Harper headquarters to retrieve the Grimoire from the safe, but the magical house would not allow them to enter and declared them Enemies of the Harpers, including Hershel, the initiate.
At Blackstaff Tower they met the great wizard, who possessed a distrust for Elminster and The Harpers and admitted he was a former member. He seemed perturbed that Lawrence had given them two relics of Necrodeimus. He took Deltron in private to enquire about Deltron’s Ring. When the emmerged from their secret meeting Blackstaff declared that Killian was to pay him 15,000 gold pieces for the trade, and Deltron was forced to reveal to his fellows that he has been keeping the ring a secret and that it may offer magical defense against the powers of the Grimoire.
Blackstaff vowed to smooth things over with the Harpers and to get Ranger Rick released from prison, but warned them that they should leave the city and avoid Harpers until this all blows over. They party expressed interest in helping with the battle against The Dead City, which had completely disappeared back into the ground when the armies attempted to take it. Blackstaff promised to have some work for them in the morning.
As they left Blackstaff Tower it occured to the group that the Joker Card might be controllable. Nuadre took out the card and attempted to will the Grimoire into their possession, however, instead the entire group was teleported to a pocket dimension where Vayne Hall dwelled. He was surprised to see them and admitted that, without the joker in his deck, he has been trapped in his dimension. The group agreed that the best way to move forward was to continue to "play his game" and earn cards by appeasing the nameless god that Vayne Hall followed.
