This sounds awesome.

Thank you so much for your compliments and your feedback!

From your response, I feel that you were brilliant in perfectly understanding my idea, when I tried so hard not to be understood with my rambling text ;)

I like the idea of cards for quests. Although I gave no explanations at all on how this game should be implemented by the players (yet), in my head they were using post-its or index cards to write character sheets and quest sheets.

I can see your suggestion for using predetermined cards for quests totally working with already established genres/settings. Something like: the western quest deck, the low fantasy quest deck, etc…
