Ok, allow me to reiterate:
Name: James Wake
Age: 15
How your character became a werewolf: In the town where James was born, the majority of the population was composed of werewolves. His father was the last of a proud, long lineage of werewolves, and had high expectations of his son. The village had a certain way of creating werewolves. They would transform the children at the age of 9 during a ceremony held on a full-moon. Being half-werewolf, the children were not attacked as often as other kinds of humans. The parents would willingly pass on the curse to pass on their lineage.
James' father wanted to pass on the curse early, feeling the second death of the Dark Lord looming. His connections to the Dark Lord would lead to an ostacization of the clan, and thus, he felt the need to create more werewolves to protect the clan from devastation. When James was six, his father ordered the ritual to be held. Before the full prayers could be recited however, the clan was attacked by a number of aurors. With name of "Harry Potter" on their lips, they destroyed each werewolf, though many died in the process. James would've been killed had his father, in werewolf form, not protected him. Trapped beneath the weight of father, James was unable to escape one of the aurors. The auror had mocked the dying werewolf, kicking it away from it's son. In a last act of defiance, James' father bit his son's right arm. The auror scoffed at the cowardly act, and finished the wolf off. He then perform a "Sectumsempra" curse on James' arm, removing it from his body, and preventing the curse from fully spreading through his body. As a result, he only bears similar attributes to werewolves, though these do not include superstrength or smell. Instead, his strength is slightly optimized, and he can understand werewolves.
That's the full explanation.
