Sell some serfs into slavery

Taxman: So, my lady, what else do you have to offer me?

Lily: I can offer some of my serfs as slaves...

You point at 5 mid aged men who were just standing by.

Taxman: Hm... I'll give you two hundred gold for all of them combined. They are old and might not have a long time to live and work efficiently.

Lily: I am sorry... The estate comes first...

Group of serfs: NO! This is outrageous! You can't just sell off your people like this! Lord Michael would never stand for it!

Taxman: Men, grab them and throw them into the cart.

They cry out against your decision, but it was totally in your power to do such things. Your people were greatly shocked at the sight as you have sold some of them off... Who comes next they wonder... None feels safe under your guidance any longer... And such feelings can easily turn into open rebellion...

Taxman: Right... 200 gold for the them, just as promised. Do you have the necessary amount of gold now?
