A/N: I re-posted this story because I'm shaking off a stalker

Delphi was watching out for Peeves as she made her way to the great lake. Peeves was like those entertaining than the muggle trolls on the muggle laptop/ipad/smart phone internet. They were more nasty than real trolls. Delphi went crazy when she heard that muggles had trolls, she was going to recruit them until they made her cry. She couldn't crucio them without breaking the laptop. No one can ever know Delphi thinks muggle trolls wereworth her attention.

Delphi cast sound magnifying spell as Peeves flew by cursing. His cursing echoed through everywhere and Flich was appeared in a heartbeat. "Today's the day I'll drive that blasted poltergiest out for good!" Delphi laughed from her suit of armor hiding place until they left, arguing loudly.

Sirius was due to meet Delphi at the Great for the potion she made him. The Grindylows, giant squid, and the small colony of merpeople living there were far from the surface. Sirius and Delphi swam near the surface for their deal where Delphi would give Sirius the potion he needed.

Delphi didn't make promise Sirius anything but a leg cleaning potion. So she did just that. She made a potion that cleans hair or extra materials off a leg. She found the potion in her collection of dark stuff.

But Delphi wasn't going to do this for Sirius for free, even if he would leave her alone in the bathroom. That was already a girls' bathroom? Even if Potty and Weasel didn't get the hint when they followed Granger Danger in there. came up with Granger Danger all by herself.

Delphi wanted Sirius to give her his voice in a dark ritual that would let her join a fake new lineage. The voice of an ancient house was necessary for this dark ritual. She would become part the b'witchering Rowles or their enemy. She get her revenge on that hag Euphemia one way or the other.

So Delphi swam towards Sirius in the Great lake with the potion vial in her hand. "I want one thing in exchange for this potion," she told Sirius.

"I'm not going to come in the bathroom," Sirius replied to her. "So if you need to be alone, even if you're sitting in a hole under the sink." Delphi was surprised he bought that lie. "What else do you want?" he waited.

"I want your voice," she said.

"Pardon?"

"I need your voice for a ritual," she told him.

"How the fuck am I suppose to go to my classes without a voice and not lose points?" he asked. "Or explain to my mental family how I lost my voice? They'll think my friends made me scream so much I lost my voice and they'll get ideas."

"It will only be once every four months," she told him, ignoring his last comment. "You'll be at Hogwarts. I will uh be your voice?"

Sirius narrowed his eyes. "How would you do that?"

Fuc, he's getting suspicious...

"Uh house elf!" Delphi replied. "I'll bring my house elf over to be your voice every time you lose your voice."

Sirius ran the idea over in his mind. "Okay,"

"ELPHY!" She called. A house elf with an air bubble, appeared on in the water with an air bubble.

"Elphy knows spells for communication sirs," Elphy showed Sirius two dark books. "Mistress' friend can trace words on with his finger, and the words would appear on the book Elphy has," Elphy explained. "If you keep your hand on the book, the book can see your recent memories as long as you keep it there. So concentrate on what you want to say. And Elphy's book will also read your mind because the books are connected."

"But why do you need my voice?" Sirius asked.

The lie came smoothly. "I'm helping a friend do a complex ritual to change their voice. They don't need to be present when I take your voice."

"How do you know this as a first year?" Sirius was was getting suspicious she knew all of this as a first year. "And how will I bring her to class?"

"She'll use invisible potion, Elphy go fetch some vials!" Delphi ordered.

Elphy disappeared for a few minutes. Then she reappeared with a few vials of invisible potion. Delphi had a good stock at her hide out, and enough galleons in her hide out so the elf could buy some potions. Elphy drank the potion to prove to Sirius that it was invisible potion. Then she reappeared after a short time.

"I've seen this ritual a lot of times at home," Delphi replied. "I'm helping a friend do it."

"Alright I'll do it," Sirius accepted that answer, because he too distracted and Elphy helped him practice with the books.

"Perfect! We need to do the ritual at a waxing moon," Delphi said.

Delphi led Sirius to the shore as nightfall fell. She conjured a pentagram and some candles. Then she mirrored it on the lake surface. She held out a dull knife to Sirius. Sirius slashed his finger and the blood dripped on the pentagram. Delphi chanted the incantation as the waxing moon appeared in the sky. After a bright flash, and some pain Sirius couldn't speak anymore. He clutched his throat as he realized he couldn't speak after he asked what happened.

Delphi gave him the temporary disappearing potion, then scurried off. But Sirius remembered something. How will I do spells in class? He traced in his book with his finger. The words appeared on Elphy's book. Elphy looked up at Sirius, "Elphy will speak for you and do the spells for you. I can even holds your wands if no one's is looking."
