AN:Hello I am ShadowDragon132 you may call me Shadow. Now this is my first story so I hope you guys like it. It is a Harry Potter/RWBY/slight Assassins Creed (for some weapons) Crossover so please favorite/follow/review so I can get some feedback. I got some of the ideas from some other stories most of which I can't remember except for FairyTailDragonSlayer I got permission for that. Thank you and enjoy. Warning Spoilers!
Harry(Hadrian) James Potter was an average 15 year old boy. He had black hair and bright green eyes he was a little skinny and only 5'10" tall. He was at his relatives house in Surrey,England he had just gotten back from Hogwarts. Now he knows that's a strange name but it is for very strange people that had very strange powers. They and he himself were wizards. They were mostly secretive race that hid in the shadows of the mundane(muggles sounds offensive) civilization for centuries to survive and they did not very much like the mundane that made them go into hiding after killing off their answers and whenever some witches or wizards are found the mundane usually burn them this caused the Salem Witch Trials to name one incident.
But I digress part of the reason that Harry is at his 'home' is because he just got back from Hogwarts and his friend Cedric Diggory got killed in the tournament. Why nobody knows Harry was knocked out by a plant in the maze and did not wake up in time to find out what happened until later. Voldemort's followers got the identity wrong and tried to use the blood of Cedric thus messing up the ritual killing all the Hocruxes(soul containers) including the one in Harry's got sent 'home' as it was summer break.
But what everybody else didn't know was that Harry had been very busy since a little before first found out that he had only accessed his trust vault at Gringott's he had Hagrid go on his way so that he could go check out his family he found there were enchanted robes of the assassins of his ancestors. They were a black and white assassins robes. He found a trunk with a hidden blade,a garrote,a sword that was a little over two feet long,and a kaybar found books that are on Oculmency,Legimency,soul magic,blood magic,metamorphagi,animagus,potions,and technique books. It turns out that the reason his hair would always grow back was because he was a also found a wand that suited him greatly 12"manchineel and Yggdrasil wood with blood of reaper and blood of phoenix. The balance of life and death. The wand accepted him completely. He also found a snake egg he kept it and it has not hatched yet in four years.
He spent the next year and a half after studying all of the books he found until he had mastered them all. He did find out that his animagus form was a black and white panther. He had after that taken to changing his hair color to half black half white since it suited the books on the weapons took a lot of time and effort but he could now do all of the assassination techniques he then got bored one day and decided to make his own sniper rifle. He called it the Black Panther. Charmed to have no air resistance and low gravity it can fire from over 3 miles away without a sound do to a noise suppressant ward built into the barrel and chamber. It is also charmed to never run out of kept all of this in the false bottom last floor of his trunk warded to his blood and his blood only.
And so after hiding all of his skills and talents he got through the years saying it was just luck and placing false memories incase of Dumbledore or Snape finding out. So harry decided to go to the Leaky Cauldron to be able to get away from the Dursley's house. He got all of his stuff and left at night and called the Knight he does blood magic he got rid of the trace on his magic there was none on his wand.
He met Tom and paid for his room and went to his room. He as he was about to go to bed heard a gentle cracking sound from his trunk. He knew the egg would be hatching soon so he quickly went over to check what type of snake it was. It was a a little Magical Black Mamba. The Magical Black Mamba are known as the 'Prince of Snakes' a little under Basilisks because they do not have the death spoke ''master it is a pleasssure to meet you but we have places we could go .'' Harry then asked her ''What do we have to do if it means getting out of here then I am all for it.'' She then replied that they had to go to the Potter Vault and grab an artifact called the beacon of remnant to go to the alternate dimension that would most likely make it so his animagus form fused partially with his body into what the dimension called faunas. He honestly couldn't care about that he had been bored as hell in the wizard world lately.
So he left and went to his vault and asked for a inter-dimensional credit credit card lucky for him they did have one that would work as long as their was money in the he went into the vault and found what it was a tablet with a red rose carving on it and so he left with the word portus.
