Hermione and Ron get in front of me. Marcus lets out a chuckle. 

"How noble of friends, though it's only a matter of time before one of you are on the lunch menu." Marcus hisses.

"What do you want with Harry?" Hermione growls.

He turns. 

"So, you're the one who smells like mud. Your blood is so fowl." He says.

Hermione looks down. He turns to Ron and sniffs the air.

"You smell pathetic. Your blood is weak." He hisses.

Now Ron looks down. 

"Marcus, enough." I growl.

"Alright, alright, I need to see Dumbledore." He says.

"Why?" I growl.

"He has the map to William's prison. I need it." He says.

"Where is the map? I'll get it." I say.

I walk forward to him.

"You can't because he is the map." He says.

My eyes widen. Ron let's out a gasp. 

"What???" I ask. 

"The Dumbledore's made the prison for the greatest wizards of all time. Over the centuries, when Albus Dumbledore was just a boy, he disobeyed his parents and took a glimpse of William's prison." He says.

I remember blood holds memories. Marcus can see my memories from tasting my blood.

"What makes you think Dumbledore would let you see the location of William's prison?" Hermione asks.

"He'll put you to the grave." Ron says.

Marcus lets out a laugh. Hermione looks away. He turns to her.

"You know me. You've read about me. You know the consequences of killing the first ever vampire." He says to her. 

She nods.

"Say it." He demands.

"If you die, everyone in your blood line will follow you to the grave." She says.

"Seeing as Harry Potter is my blood line and William's, you can't stop us." He smiles.
