Can dragons be defeated?
Sure they can, but is it plausible? I know, I know, plausibility, is something subjective when we are talking about a magical fantasy world, so let me better explain where I am coming from and where am I going.
I have a player that totally despise the idea of beings from the size of a dragon's toe facing a Gargantuan Magical Intelligent beast. He can't concede on that. There is no argument, no magic weapon, no number of warriors, nothing. In his words "We would need an army, all fully equipped with very powerful weapons, and a lot of luck to get a small chance to survive. There is no such thing as a dragon hunt."
Neil Gaiman said that one of the reasons why he wrote Coraline was because he wanted to tell his kids that dragons could be defeated. He even quoted GK Chesterton on it.
So, how do you cope with that?
How do you make you dragon quests plausible and interesting?
Is my player right? Or Gaiman/Chesterton are ?
What do you think?
