Baptism of Fire - Andrzej Sapkowski

It’s impossible to repay something that has no price. Some say everything in the world–everything, with no exception–has a price. It’s not true. There are things with no price, things that are priceless. But you realise it belatedly: when you lose them, you lose them forever and nothing can get them back for you.

"What a company I ended up with,’ Geralt continued, shaking his head. ‘Brothers in arms! A team of heroes! What have I done to deserve it? A poetaster with a lute. A wild and lippy half-dryad, half-woman. A vampire, who’s about to notch up his fifth century. And a bloody Nilfgaardian who insists he isn’t a Nilfgaardian.’
‘And leading the party is the Witcher, who suffers from pangs of conscience, impotence and the inability to take decisions,’ Regis finished calmly. ‘I suggest we travel incognito, to avoid arousing suspicion.’
‘Or raising a laugh,’ Milva added."

I predict a bad end for your race humans. Every sentient creature on this earth when it falls into want, poverty, and misfortune usually cleaves to its own because it's easier to survive the bad times in a group helping one another, but you humans you just wait for a chance to make money from other people’s mishaps. When there’s hunger you don’t share out your food you just devour the weakest ones. This practice works among wolves since it lets the healthiest and strongest individuals survive but amongst sentient races such selection usually allows the biggest bastards to survive and dominate the rest. Come to your own coclusions and make your own predictions.

Everyone has some kind of debt <…> Debts and liabilities, obligations, gratitude, payments, doing something for someone. Or perhaps for ourselves? For in fact we are always paying ourselves back and not someone else. Each time we are indebted we pay off the debt to ourselves. In each of us lies a creditor and a debtor at once and the art is for the reckoning to tally inside us.
