POV of "Madman Black"
By-orange story
In the dreariest of places where nightmares came to life, happiness was not known to such people, Azkaban. Like a living hell on Earth. And guess who was in there? Black.
Publicly named "Madman Black" by the wizarding community he laid there in his cell. Emotionless or so it seemed...
He was just reflecting on his past life, but that soon flashed to his ambitions of today and his plans of escape. For you see he was no madman, he was a man with a vendetta with ones called Voldemort and Pettigrew and a concerned godfather.
I have to get out of this bloody hell-hole but how!? I'm not far off of going insane! Hold on...they only sense humans... but animals...that's it! Bloody hell that's it!
I'll turn into my animagus-self! It's so simple! I swear to God Pettigrew, you bloody murder I'll see to it you meet your grave then I'll deal with that damn Voldemort leader of yours!
But pretty soon his thoughts of revenge and avenging his dead friend, James drifted off to James' son Harry Potter, his nephew. Something worth more than getting revenge, about keeping his promise.
Harry...I know your at Hogwarts under Dumbledore's watch but anything could still go wrong, but I still have to take care of you as I promised James.
Damnit, Remus I hope your watching my Harry! I'll keep my promise James, I swear. I'll take care of your son and protect him and avenge you and Lily's deaths! I swear it!
And when he came out of his aggressive reverie he decided to act. He changed from his now bedraggled-self from being in Azkaban to his black dog-self, Padfoot.
And he made his escape.
I'm coming to you Harry, I'm coming!
