“Every service had a price. Every object a value. If someone made you a sword, you paid him the appropriate amount or traded something of equal value with him. If a man saved your life, you either paid him the amount you considered that life worth, or you saved his in return. Until either of those things was transacted, you were in his debt. It was business. And if Balthazar believed in anything with religious fervor, it was that.”
