Quest of the Dark Knight

The sun had hardly risen when the stranger arrived on Count Tregor's doorstep. Normally, Numnir wouldn't have let someone in so early – Tregor was a most insufferable man before he'd had at least a pint of coffee – but the stranger had reminded him that dragons wouldn't wait for the pleasantries. So into the hall they went. Numnir was pleased to see that this man, at least, had wiped his feet.
“Count Tregor, I presume,” said the stranger, dipping his head a little.
Tregor was grumpily straightening his mustache, which took even longer to wake up than he did. “Who are you and what is your business?” he asked.
“My name is Sir Isaac,” said the man. “I heard you needed assistance with a dragon.”
“Oh!” said Tregor, snapping to attention. Finally, a solution! “Yes, we seem to have an unwanted new neighbor on the mountain just outside our gates. There will be a handsome reward for the man who subdues it.” He looked Sir Isaac up and down. “Do you think you're up to the task, Sir Knight?”
“I make no guarantees,” said Isaac, “but I shall see what can be done, your grace.”
“That's the best news I've heard all week,” said Tregor, heartily shaking Isaac's pale hand. “Numnir will give you any supplies you may need in your quest. If you succeed in eradicating this nuisance, you shall receive five hundred doohickies and a barony, of your choosing, within my realms – so long as you don't choose my capitol, of course!”
“That is most gracious of you,” said Isaac. “I shall embark immediately. May I have a look at your food stores?” he asked Numnir.
“Best of luck, my good man!” said Tregor as they left the room.
