When the inquisition gets their hands on the schematic she was preparing for them, it would make the spatial "Mansion" seem more like the left over back room closet it really was.
"I also want the two weeks vacation, every year for the duration of the contract" Lilu added. She knew what she was doing here. She was essentially getting the inquisition to pay her like an employee, with paid vacation, for fifteen years, all for the price of a single schematic. And not only that, for everyone one that sold, she would collect a ten percent royalty. This would end up like a huge bonus for her. And she still didn't have to sell out to them.
