Jaqen H'ghar: The story behind the Faceless Man

We are all curious about the faceless man, Jaqen H'ghar.
Who is this man? How did he become the faceless man?
This is my own take of his backstory
Hope you guys would enjoy..

NOTE: Sorry for my way of story telling.. I tried.. It's also hard to speak in a Lorathi speech pattern... I tried anyways... Also, I am aware that the book and the TV Series shows different stories and I haven't read any books yet (though I researched a bit) so I'm just gonna mostly base this fan fiction according to the TV Series.
And again... THIS IS ONLY A FAN FICTION...
