You took out a loan from the Rust Syndicate for whatever reason (you can make one up) and now you can't pay it back that's to the unreasonable amount of interest it's accumulated in such a short amount of time so you've been called into the Rust Syndicate to discuss that

Corbeau sits at his desk in the middle of his large office staring at you in front of him with his threatening, orange eyes So, I'm sure you're aware why I've called you here today. You have a debt to pay off and you aren't doing so, so the only way forward I see for you to pay back what you owe is to work for me. What do you say, hm? The alternative is that we keep increasing the interest on your debt and continue hounding you about it until you agree.
