All about one of my characters: Jacob

Street smart and brave. Stout and informal. Lawful and strong. Jacob is one of the later-occuring characters within book 1, and throughout subsequent works he takes on a more profound role. He is a human in his late twenties or early thirties. Although it is not ever mentioned what his last name is, I have theorised that it is not important enough to mention and will therefore give him none.
What is Jacob's role in the story? He is met at the very end of book 1 and provides the characters an inside contact into the city they are trying to sneak their way into. He is the ringleader in a band of vigilantes that inhabit his home city and they are known as the Iron Hand. When something happens to the Iron Hand to stoke Jacob's anger, he sides with Anar and his troope. Jacob the vigilante doesn't play much of a plot related role in the story. Where other characters make deep decisions about the way things go, Jacob utilizes his intelligence to the aid of another. He helps Anar with his task in the city he lives in and he works to fight against the enemy with his street hardened skills.
Jacob has a backstory which goes above and beyond most other characters of his importance. Being a vigilante, as his backstory went, always meant he was defying the odds and working for the city, taking it easy in the local tavern when on his off time. During his early life around his late teenage years, Jacob took a wife and had two daughters. He could not devote enough time to them and his drinking (vigilante work in the city is hard) seperated him from her. In the end he was found passed out on a table, drunk as ever. Disgusted at her husbands show of foolishness and apparent inability to visit him, Jacob's wife left him forever. To make it worse Jacob has since found out that his wife informed their children of his fallacious passing. By book one he is a hard bitten brute with nothing to lose although his heart is still open to empathy.
Jacob fights with dual rapiers and wears a dark red hood (he stops wearing it forever by the end of book 1). His face is scarred and his hair is "the colour of dead grass". Though I do not mention it, his voice has a heavy Irish sounding accent to it. He is quite street smart and very skilled with his weapons.
