Loyal and Brave. Yet Broke?

What I have noticed throughout this book is that, even though these great fighters, who are loyal and courageous, they never have any money. The only time they are rewarded for their works is in the beginning of the novel, in Chapter 6, when they take out the Cardinal's men. Besides that, they always struggled to equip themselves due to lack of money, and, even with such a challenge, they always managed to equip themselves, there were a few times where they didn't even have equipment.

What I got out of this is the value of our heroes. They do not fight for money, they fight because of their loyalty to the king. They do not live miserably, but they don't seem to have much money to spare.
