You're a former firefighter who developed a bad case of pyromania, landing you in prison after killing several people, which obviously lead to Urbanshade getting their hands on you. And being the firecracker you are, you get special rules: a complete ban on saving and picking up any potentially flammable objects, even a lamp was prohibited. Every time you try to pick something like that, the bomb in your cylinders starts beeping, forcing us to keep your dirty little hands to yourself.
Then, of course, you meet Sebastian, which you HATE. For some reason though, he seems to actually like you, enjoying the fact that you actually were some sick and twisted fuck who deserved to stay in prison. Plus, he enjoys watching your face as you stare at his lighter any time he flicks it on.
And, he'd be more than happy to sell it to you, for a price that is...
