A demon at Hogwarts

Prologue

Damian's pov

Dear diary,
Usually, I wouldn't see any point in doing something like writing in a diary. Something like this is pathetic and weak but it's all I have to talk to. Everyone else is gone, or rather, they were never with me to begin with. Father married Catwoman today and the harlot brought home a cur that she had with father a few years back. Her name is Candice. What else is there to say. Everyone likes her more than me. She's sweet, innocent, loved and most important of all, she's not a monster like me.

Dear diary,
Father is looking at me less and less these days. And when he does, it's always a scowl. Catwoman ignores me anyway, I mean, who would love the child of your husband of another woman. My brothers love Candice more. The other day, I saw them take her to a carnival without me. It's not like I even wanted to go but seeing them like that made my chest feel tight. It became harder to breathe, I hope it's not an illness. Even if it is, I'm the heir to the demon's head and the son of the bat, I can withstand this. 

Dear diary,

Candice seems to have realised the family situation. She's started making jabs at me like saying that I was unwanted and better off going back to my whore of a mother. I punched her for that. Father hit me and grounded me in retaliation. Everyone came rushing to Candice and looked at me with scorn. No one even gave me a chance to explain. 

Dear diary,

Mother just came to talk with me. She was so mad. She said that I was worthless and a failure. I had failed to appeal to my father. She told me to return with her back to the league. She said that she'll continue to train me, to make me better. But I can't do that. My time here has made me realise that what happened at the league is abuse and what's happening to me now is abuse. If I go back, I'll break and die. Either that or grandfather will take my body as a vessel. I knew about that. I wasn't an idiot, I knew how to spy. I also sneaked into grandfather's private study and learnt to utilize demon magic. I'm glad that I took those books, now I can continue. I barely managed to escape mother but just barely. I was gravely injured but when I entered Wayne manor, no one cared. Only Pennyworth came to dress my wounds.

Dear diary,

It's become impossible to live here now. Mother wants to kill me. Father calls me a monster. My brothers hit and kick me all the time. Candice tells me I'm better of dead and gets me in trouble. Catwoman just ignores me and Pennyworth only looks at me with eyes of pity, but he can't do anything. My 11th birthday is in a few days but it doesn't seem like anything will happen.

Dear diary,

It's unbelievable! Today was my birthday and at first, everything seemed like any other day except mother had left me a box with a dead snake. A warning, I suppose. But just as the day was drawing to a close, an owl flew into my room. After the momentary shock, I realised that it was trying to hand me, a letter? It was weird. It had a red seal and on the back, it was addressed to:

Mr D. Wayne

3rd bedroom of west wing

Wayne Manor

1007 Mountain Drive

Gotham 

United States of America

I got nervous looking at how accurate the information was. Maybe that's what compelled me to open it. The letter said this:

HOGWARTS SCHOOL of WITCHCRAFT and WIZARDRY

Headmaster: Albus Dumbledore

(Order of Merlin, First Class, Grand Sorc., Chf Warlock, Supreme Mugwump, International Confed. of Wizards)
