I needed money for some new chainmail so that I could survive the run through Blackfire Pass, So I took a loan from Bruno Ballcrusher back in Marienburg. Orcs massacred the caravan and now I'm impotent and live in a cell with a pedophile, a serial rapist and an elf.
Now I lent you money. And I don't see it. Do you know what happens when I don't see my money, Fagin? People get hurt. People like you get hurt. Do I make myself clear?
