Sirius Black was not all what he appeared to be by wizard standards. He was a Peacock from China one of the ruling families for that matter. When he was a young peacock he was very sick. His parents could not understand why this was till one day a human showed up with a letter inviting him to go to a human school of magic.
He had been excited at the chance to learn to control the powers he had. Once he had a wand in hand he got better so it went under the disguise of a human that he went to school. Where he met a pureblood wizard by the name of James Potter who was rich. They became fast friends.
When James and Peter were in there fifth year they completed the Animagus Transformation. He showed them his true form as a Peacock solid white with bright red eyes on his tail feathers. It was all to do with a fellow roommate by the name of Remus John Lupin who was a Werewolf. They thought it would be a good way to help him out.
Right after Hogwarts James Potter married Lily Marie Evans. He was of course best man but not as Sirius Black he was best man as Shen. He was also named Godfather of their son when he was born. The child name was Harry James Potter. He had agreed with Peter over the matter of who was secret keeper.
Shen arrived at Godric Hollow before Hagrid. He was in his peacock form he could hear Harry crying a great deal. He lifted him up in his great wings.
"I know little one. I miss them too"
Shen run down the stairs and out the door. He was fixing to call for his airship when an voice ring out from some thirty feet in front of him.
" 'O the ruddy 'ell are you" Hagrid said looking at the Peacock confused. "Where 're you going with little Harry Potter" he said even more confused.
"I am Shen" Shen said holding onto Harry more protectively his tail feather standing up and fanning out. "I am a friend to the Potters. I have found them dead in the house. Harry is my godson. I am taking him home with me"
"No" The giant said not liking the peacock and a little confused about how it could be talking for that matter. "Dumbledore said little Harry going to his Aunt and Uncle"
"Those…Those… Those Cretin" Shen made a really disgusted face. "I would die before that happen" He made a snapping sound with one of his wings which then brought from the shadows a very silent airship above it were several Wolven like creatures on it.
"Easy now" the giant said still puzzled and a little calmly. "No enemies here. But Dumbledore wants-"
"Screw what Dumbledore what he just an old man" Shen said. "While I am grateful forever to him for letting me come to Hogwarts. But I will not let a godchild of mine be raised in a filthy Human home. Those people despise anything and everything to do with magic. I am going to take my godson and raise him to be the heir to my clan" he said not all happy.
A metal cable came down with a platform attached to it and a second cable came down as well. Hagrid still was not sure about what he was seeing or hearing.
"Goodbye, Hagrid. I am off to kill Pettigrew. I will raise my godson how I see fit"
Hagrid watched dumbstruck as the ship disappeared leaving with the little savior on it. Shen held his godson close as they flew away from Godric Hollow.
