Okay. This part is original from me:
Chapter 2: Slytherin Intelligence Gathering
Philip Granger and his wife were feeling only a slight bit guilty. They had decided to keep Hermione from contacting her friends over summer because of what had occurred the previous June in the Ministry of Magic. Therefore, they had decided she deserved a little reward before she was sent back to Hogwarts in September.
The two walked confidently into the Leaky Cauldron.
"Hello!" called the bartender. "Can I help you?" the man asked with a pleasant smile.
Philip nodded at the man, noticing (in passing) the man's horrible teeth. "Yes. My daughter is a Hogwarts student and my wife," he nodded at the attractive lady he was with, "and I want to pick up a small gift for her. Can you help us into the Alley?"
Tom beamed. "Of course! Of course! Follow me."
Off to the side of the bar Valerius Crabbe, Uncle to Vincent, and brother to Augustus, was drinking a pint of ale. He, like many family members of those who had been present at the Dark Lord's annihilation, was in town to learn what had been decided by the Council of Evil.
He had listened with dread when the description of what had happened was given. Therefore, the new rule was "No Killing or Baiting Muggles" and "Keep you Head Down." Another was, "Hermione Granger and her friends and family were OFF LIMITS."
He, like many Dark wizards and witches, had learned the exact description of the Muggle Dark Lord who had gotten the Dark Lord killed. And, Morgana help him, the man in question had just appeared in the Leaky Cauldron. He decided to keep an eye out and make sure none of the Dark elements did anything too stupid. Therefore, when the Muggle Dark Lord (called a Dentist apparently) and Lady were being led back to the Alley, he performed a supersensory charm and followed them (very discretely).
The charm had caught the conversation in the middle. "… getting better," the woman said. "We just have to make certain she isn't too upset with us."
The barman cheerfully asked, "Oh? Why is that?"
The Dentist chuckled ruefully. "We might have upset her a bit when we stopped her from writing to her friends Harry and Ron. She needs to heal and we don't want her too worried with whatever is happening."
The barman shrugged even as he opened the gateway. "Just be careful. Some Dark elements" the barman scowled "might get upset with an unaccompanied Muggle going through the alley."
The Dentist laughed. "It isn't a problem. We'll be careful. To be perfectly honest," and here he whispered so low that Valerius almost missed it, "my daughter frightens me far, far more than any Dark wizard ever could."
The three laughed together even as the couple walked through the arch.
Valerius Crabbe felt his insides clench even as he pleasantly nodded to Tom on his way through. If a Muggle Dark Lord was terrified of the witch, how bad could she be?
Velerious found an out of the way spot to watch for the Dentist and his wife to leave Gringotts. They were obviously there to get Galleons. He saw a fellow Dark wizard and motioned the man over.
"Hello, Crabbe. What can I do for you?" Darius McNair asked.
Valerius glanced around to make certain they weren't being overheard. "That Muggle Dentist just went into Gringotts." Suddenly, Darius looked just as worried as he felt. "I need you to pass the word to any of … our people to make certain they keep out of the man's way."
Darius considered what he had just been told. Before he could reply, Valerius felt a poke on his back.
Rockspear was standing his post outside of Gringotts with his fellow warrior. Suddenly, he noticed a furtive figure keeping a watch out toward the front of the bank. He frowned. This wasn't good. He motioned his head slightly and, using hand signals, he told he fellow guard that he was going to investigate. The other guard nodded.
When the furtive fellow was distracted by another wizard, he made his way stealthily behind the two. He heard the last words "… the man's way," just as he moved his spear forward.
In a low, menacing voice he asked, "Why are you watching the front of Gringotts so carefully? Are you so foolish as to be planning to steal from us?"
The two wizards sharply turned. He noticed that neither moved toward their wands, so he didn't move the spear to keep it in place for attack.
The younger one answered with some fear, "No! No. Not at all! We're just … well we're kind of keeping guard on one of your customers."
"If that's true, why aren't you with them to keep them safe?" Rockspear asked.
The two wizards looked at each other and the older one nodded. "Look. You remember the Muggle couple that just went in the front door?" Rockspear nodded. "He's a Dentist." Rockspear didn't know the word and didn't react. "A Muggle Dark Lord."
Rockspear looked dubious.
The younger one sighed loudly and glanced around. "Look. The man who just went in your door just got the Dark Lord killed."
Rockspear was surprised. Even as he moved his spear to a less threatening position he barked, "Explain!"
And so the two did. Rockspear was flabbergasted even as he listed to the explanation. "… and so the Council has warned his former followers that the man wasn't to be touched. We're just making certain none of our people get any bright ideas. I do not want to cheese off the man who got the Council of Evil to kill the Dark Lord. And I especially don't want to upset the man's daughter! Because if he's under the protection of the Council and she terrifies even him – how Dark is she?"
Rockspear contemplated what he was told. Finally he nodded. "We will keep an eye out to ensure their safety. Perhaps, when the two are back in the Muggle world, you can return and report this to my superiors. Gringotts always treats favorably with those who ensure we make no mistakes and lose profit. And what you know might just help with that. Are you willing to come back?"
The two Dark wizards looked at each other and nodded. The younger one said, "As soon as we're sure they're safe, one of us will come back. The other one has to report to the family's what we have learned today."
Rockspear nodded. "Done and Done!" He looked suspiciously back at the two. "Make certain you do. I wouldn't like to report you to my seniors as uncooperative." Rockspear grinned viciously.
The two Dark wizards nodded.
Valerius Crabbe flooed into his brother's home with Darius McNair. The two were greeted by the Crabbes' house elf. "Tibby! When is my brother?"
The house elf responded with some fear, "Master is talking to Master's guests in the Master's study."
Valerius nodded and called out, "Follow me!"
Unfortunately, or perhaps fortunately, for Tibby, the order to his fellow wizard wasn't clear enough and she though she was being ordered to follow as well. Because of this, the two wizards weren't alone when they rushed into the study. Tibby tried to remain inconspicuous even as the rest of the wizards and witches in the room looked to see who had just come in.
The Death Eaters and their families were in emergency meeting due to what Narcissa Malfoy had heard from her sister. He almost yelled, "Where have you been? We've been trying to get a hold of you for hours!"
Valerius nodded. "I'm sorry, but I saw the Muggle Dentist and his wife visiting Diagon and I decided to follow them and make sure no one made any mistakes." He gulped. "I learned a few things."
Everyone looked interested. And so the two wizards explained what they had seen and heard. Darius put in his final two knuts. "I think what Valerius here learned was the most vital thing: The Muggle Dark Lord is terrified of his daughter." He looked around. "What do we know about Hermione Granger?"
A gasp was heard from an unexpected direction. Everyone in the room turned to see the Crabbes' house elf standing in a corner covering her mouth. "Tibby! What are you doing here?"
Very distressed, Tibby replied, "Master's brother said to follow him! I be's good elf and follows orders! Tibby was ordered to follow brother's orders just like they came from Master!" She reached to turn her own ears. "Tibby didn't know she misunderstood!"
Just as she started twisting her own ears, Augustus ordered, "Stop that! Why did you make that noise when McNair asked about Hermione Granger?"
Tibby moved from one foot to another even as she quietly replied, "Tibby was surprised. Tibby learning things about Harry Potter's Granger. Dark and terrible things. Things that make house elves full of fear. We's not want to cross Dark Lady Granger!"
The Death Eaters gave each other knowing looks. It was obvious that they had missed the clues. Finally Augustus said, "As your Master, I order you to tell us what you know about the Dark Lady Granger!"
Tibby almost rushed to reply, "Dark Lady is making all house elves in Hoggywarts terrified. House elf must have made her angry. Only Dobby who Harry Potter calls friend is being safe in cleaning Gryffindor. Master Malfoy's son keeps making Dark Lady Granger mad!. Only threat to Dobby's master Harry Potter making her more mad! When someone makes Harry Potter in Danger, Dark Lady Granger be working hard to make him safe! She gets angry face and house elves hide more! Harry Potter and Harry Potter's Weasey treat Dark Lady Granger as she is their Mistress." Tibby paused." Even though Harry Potter keeps house elves safe from Dark Lady Granger when he can." This last part was said almost with a tone of wonder. She didn't get a chance to tell about the hat's and scarves when she was interrupted.
Narcissa Malfoy had turned white when she understood exactly how bad her information was. She called out, "Merlin!" Everyone looked over at her. "Don't you all see? Think about the Muggle which terrifies the Council. And then think about the fact that such a Muggle is terrified of such a witch. And a whole race of Magical creatures is also terrified of her."
The rest of the room thought about it.
"And then think about this: Bellatrix is moving even now to torture and kill Harry Potter! Can you imagine what the Council will do if the Mud … Muggleborn loses control because we allowed her friends to be threatened?"
Pansy, who had come with the Parkinsons, gasped out, "Merlin! She'll kill us all! Every last family member!" Pansy looked around. "The … Muggleborn Granger doesn't do things by half."
The rest of the magicals in the room finally began feeling the fear and terror which Narcissa Malfoy felt justified. With heavy heart she said, "I learned from Severus where the boy lives in the summer. Who is going to go and make certain Bella and her husband and brother are stopped before they doom us all?"
Finally it was decided that Augustus and Daisy Parkinson would lead a group to capture the rogue Lestranges. And then they would be turned over to the DMLE – no one wanted to actually kill the group.
It was a week after this meeting when the Death Eater families were once again meeting together.
In addition, many other Slytherin students (mostly the girls) and THEIR families were also in attendance. Narcissa Malfoy called the group to order.
"We stand here at the brink. We and our families have systematically insulted and abused what we have now found out to be a Dark Lady in ascendance. What will we do now to prevent catastrophe?"
