While I'm not a GM of this RP, I can tell you that I seriously doubt hatakekuro's character will be approved as it is. He's hella OP. 

Something to note when writing backstory: Make it make [i]sense[/i] in context. 

[quote=hatakekuro]Durandel was only a small child when he has abandoned in the cold winters of Ferox.[/quote]
Small child means five to about twelve, right? By that, let's go to the far ends of the extreme in this example, and assume that Durandal is [i]twelve[/i] when he does the following actions 

[quote=hatakekuro]Durandel wanted to fight for his life, so he can live even though the odds were against him. It was only natural for him to have a desire to fight; it's a pure animalistic instinct that all animals, including humans, have.[/quote]
Like hell. This is a twelve year old child. However, that could be explained because he's a taguel and I have no idea what's up with their mentality. 

[quote=hatakekuro]Hours went by as he made his way through the icy forest, only for brigands to find him and attempt to kidnap him. These weren't ordinary brigands; they were ones stealing women and children to sell them as slaves to make a profit. This group attempted to grab the boy and steal him away...it didn't go well. Durandel stole one of the daggers being pointed at him and he quickly killed them all, their bloody painting the ground crimson. Meanwhile, soldier's from Ferox had discovered the whereabouts of the group of brigands and went immediately to put an end to their trade only to discover them already dead with only a young boy standing their with his hands covered in blood and a smile on his face.[/quote]
This is the heart of the issue, right here. After trekking through a frozen forest for [i]hours[/i] with no food(A feat that would down a full grown, healthy man), said [i]twelve year old child[/i] meets brigands who are trained in the art of taking people alive(Something a lot harder when you consider how easy it is to kill someone with an axe), tears a knife away from a full grown man who's both well-fed and wearing proper clothing for the temperature, and then proceeds to butcher the group of men. While nearly freezing, probably starving due to burning all the calories just to stay alive, and most of all, twelve years old(A time where if you have muscles, you've messed up your body in the long run). And then the proper, trained soldiers show up.

The troops were astounded and confused by the spectacle. They didn't know what to do with this kid until they decided to bring this child with him back to the barracks. After much discussion, they brought Durandel into their ranks as a trainee. As the years went on, the boy had become a man and as he became a man, his fighting skills surpassed even the mightiest of generals in Ferox's army. He became famous through out the continent for his beast like fighting style and his undeniable skill. As of now, he has been on a journey to go find as many strong opponents to duel to the death with.

Astonished and confused? They should have killed him on the spot, if this strange little child is smiling after killing several dozen men. Now then. The last part about the generals means that he's currently one of the most powerful people on the continent, despite having a crippled body due to his muscle structure being horribly developed at the age of twelve. 

 

To recap. I don't think you'll be accepted until your backstory is reworked into something that doesn't instagib any other person in the RP, [i]or[/i] at least makes sense.
