Ok, I decided to side with the Dragons, so I want to complete this quest. (not sure what the reward is...?)
I've killed all near the 'tents' all & their pets, everyone in the village and everyone in the castle (where you meat Sir Charles Quixote), but the dragons says there are still more....
I flew round the map (incl edges) looking for red or green dots, but I cannon find any
Am I missing something?
