Narrator's POV

For Christmas, Remus and Sirius gifted him a diary.

Harry didn't get around to using the diary for a couple weeks, but when he did he wrote an introduction to his life.

Harry redipped his quill into the inkpot and much to his surprise, the words disappeared and new ones appeared.

"," Harry wrote ""

"That's good." Tom wrote "What exactly does Ron and his sister do to you?"

"" Harry wrote

Tom didn't respond after that for several minutes and eventually returned and talked more.

Neville opened his diary Sirius and Remus had given him and he wrote to his friends, Bellatrix and Rodolphus, or as they —weirdly— asked to be called, Mumma and Papa.

And the writing disappeared like it always did and new writing appeared.

"" Neville wrote

"Oh, well did you talk to Harry or Hermione? -Papa. Or maybe Luna? Do you still have a crush on her? ~Mumma." The diary wrote

"" Neville wrote

"I know, my darling, but we can't risk a Order member finding out about us or they will destroy the diary and we won't be able to talk to you anymore. ~Mumma. You didn't answer Mumma's question? -Papa." They wrote

Neville blushed as he wrote ""

***

Luna opened her diary to talk to her friend Xenophilius or as he asked to be called, Dada.

And the writing disappeared and new writing disappeared.

"" Luna wrote

"It's a darn shame." Dada wrote back

***

Hermione sat at her small bed and opened her diary to write to her friend Barty, or as he asked to be called: Uncle.

As always, the writing disappeared and new writing took its place.

"" Hermione wrote

"Find anything interesting?" Uncle asked

"" Hermione wrote back

A month before Christmas or Yule, Remus thought of an amazing idea and presented it to the Death Eaters: connected diaries.

The diaries would be given to the stolen children and Harry so they could communicate to those that cared about them: Rodolphus and Bellatrix to Neville, Barty to Hermione, Xenophilius to Luna, and Voldemort to Harry.

To say it simply, the Dark wizards and witch loved to idea; Bellatrix hadn't looked happier in 13 years...
