The witch on the outskirts

The only light on the outside of the building was the dim yellow porchlight, which couldn't have illuminated more than 10 feet away. The house on the outskirts was old and dilapidated, with it's white paint peeling off and several windows cracked.
"This is the address" Ami thought, looking up the unsettling old house.
Ami climbed the steps, creaking under her boots, and crossed the dimly lit porch to knock on the door. Several minutes of silence went by. "Great, no one home" Ami turned to leave when the door creaked open. An old woman with a hunch back and a wrinkled face peered out from the darkness of the door.

"Yes?" The woman questioned
"Beatrice, the witch?" Ami asked
"I am" the woman responded.
"I'm Ami Va-"
"I know who you are young lady", the woman interrupted, "What do you want"
"I need your help" Ami said, a tinge of desperation in her voice.

Beatrice let Ami in to the house, Ami was overwhelmed by the smell of mothballs and various potions. Beatrice waved her hand, illuminating the living room with candles.
"What do you need child?" Beatrice asked
"I need a way to enter a vampire's nest undetected, I believe they have my friend and I need to rescue her."
Beatrice nodded, "And if they've turned her?"
Ami shuddered at the thought.
"Then I'll put her out of her misery."
"Misery? By all accounts being turned into a vampire is one of the greatest pleasures imaginable, doubly true if the woman is the dark bride" Beatrice responded.
"Dark bride?" Amy asked, her hand subconsciously touching the spot on her neck where Drax's fangs had touched.
"Yes, prophecy says that Dracula, or his heir, has a destined dark bride. One woman who he will be drawn to, above all others. So too, will this woman be drawn to him. Once he turns her, she will become his queen of the night. Together it is said they will have enough power to conquer the world." Beatrice explained.
"After I rescue Allana, I'm going to find this dark bride and kill her before Drax can turn her!" Ami declared.
"I'd be careful." Beatrice cautioned "prophecy is a powerful thing....even more powerful than bloodlines."

"I can worry about prophecy later! Please Beatrice, do you have any way into the nightclub? An invisibility potion?"
"Won't work" She replied curtly. "Vampires can see too well."|
"There is however an alternative." Beatrice continued."
"Please, anything!" Ami begged
"I have a spell that can change your appearance, even to the point where vampires cannot tell the difference. You will still look like you but..."
"But what!" Ami asked
"As a vampire." Beatrice finished.
"The spell turns me into a vampire! Not in a thousand years!" Ami shouted, disgusted
"You don't listen child!" Beatrice scolded. "It doesn't turn you into a vampire, it merely makes you look like one, minus the fangs. You'll have to put those in yourself. I have fake sets of them in the back. No blood drinking required"
Ami pondered her options, she had to save Allana.
"There's no other way?" Ami asked.
"None that will fool the vampires so completely." Beatrice stated.
Ami looked at the floor in silence for a short while, then met Beatrice's eyes.
"Alright, perform the spell." Ami said.
