12 Years Old.

The loan business of the gang was a front, but it was a wealthy front.

It wasn't producing as much money as their prostitution business. In fact, it was hemorrhaging money because they were lending money that was never going to get repaid, but it was also in charge of all their money, which made it very easy for Arthur to acquire most of their liquid assets.

He earned 57 gold coins from the raid and more than a hundred thousand karma points from the lives of the gang members even though he only managed to kill half of them.

He couldn't kill all of them because their business was widespread and because they were already alert as soon as he appeared in their territory.

So some of them were able to get wind of his massacre of their gang members. These people told others and escaped with their lives immediately.
