Melchior

One fancy lad - the envy of dragons elsewhere, he is swift, smart, and incredibly wealthy. He tends not to be impressed by humans and those he deems as "lesser beasts," but as far as dragons go he can be reasoned with. He doesn't engage in matters that bore him, and doesn't tolerate any siege upon his lair. Still, he doesn't aimlessly raid and plunder castles for treasures.

He won't say so, but he does appreciate eloquent flattery and those who bring him fine gifts. Maybe, just maybe, if you impress him with an extravagant enough gift, he'd be willing to do you a favor, but don't hold your breath.
