Voldemort
When I returned to the manor I wasn't greeted with Harrison's cry. It was absolute silence.
Had I put a silencing spell over his room in my hurry? Did I forget to put up the protection charms around the manor? What if something happened to Harrison?
My thoughts began to race and my breathing quickened. I was just standing in the exact spot where I entered as I began to shake with overwhelming fear. I couldn't just stay here fearing for my son. I had to go to his room and find out for myself.
I found it difficult to start moving with my blood pounding throughout my entire body with an echo. But once I started moving I found it was easy so I began running until I got to his room.
The door was wide open. And so was the window. Looking into Harrison's cradle he was no where to be found.
Raising my wand I drew the outline of the Marauders werewolf tattoo.

Moony in his day-time form appeared a few minutes later.
"Remus, someone took Harrison. Can you let Moony smell who was here?"
Remus or now Moony had a lust for blood in his yellow eyes.
He sniffed the air and making his way over to the cradle Moony retreated giving control back to Remus.
"You, Alpha, Pup, and Dumbledore have been here."
I could tell my eyes had flashed red because Remus took a step back away from me.
"Um, Lord? So did you and Alpha go through with your plan for the Potters?" He asked carefully
"Yes we did."
"What's your plan on getting Alpha back?"
I could see that it was Moony who was saying Alpha because of the werewolf pack law when referring to the Alpha a pack. But Remus had no regards of the laws and wanted to call the Marauder Alpha, Prongs.
"You and your mate will be filled in with the plan when the time comes. Do what you possibly can find to my son."
Remus nodded and apperated away. Leaving me alone in solidarity. My only enemy was the silence that sufficated me. Making me lose my grip on my sanity. The only thoughts on my mind were of revenge on Dumbledore and where Stag hid his Horcruxs.
Dumbledore
I am surprised that Tom- or now Voldemort -and his mate didn't put up protections around their son's room. It was just to perfect.
The little monster-born screeched and cried calling out incoherent words. I had to cover my ears just to formulate any thought of casting a spell. Once I did I could at least audibly cast spells.
"Somnumia" and the little beast fell into the dream realm.
Okay only forty-five minutes... where should I put the little monster-born?
Black Wood Orphanage.
Apperating to appear in front of the only wizarding orphanage. Well not exactly because Black Wood was in the muggle world. It was made specifically for children who have lost their parents in the war, both Dark and Light. Hopefully trying to convert the children from the Dark over to the Light. But the children are stuck in their ways from what I've heard.
Putting the child down in front of the door I remembered that most people who leave children at orphanages at least leave the child's name.
Remembering back to his dark room there were bright green lettering above the crib spelling out Harrison.
Harrison Riddle.
Ugh what a horrid name. I left just before he woke up crying from the cold and waking the care taker of Black Wood to find -unknown to them- the dark heir on the door step.

Key
Somnumia~ a spell for deep sleep. If the caster uses a wand then the victim will stay asleep until awoken. But if the caster uses the spell verbally then the victim will go into a deep sleep but the caster only has a limited amount of time until the victim wakes up.
Monster-born~ the word Dumbledore uses to describe Harrison. The reason is that Dumbledore thinks that 'Voldemort's mate has to be just as evil if not more so to be his mate and conceive the dark heir'
AN- Somnum is the Latin word for sleep. And I really hope the Key makes sense if not let me know.
