In my own campaign, heroquests have been the primary vehicle for players to discover and acquire Draconic magic. And now that they have learned some they are in the process of setting up their own means of worship to replenish their abilities in the mundane world. Secretly, of course, given current attitudes towards this sort of thing.
I have always loved the idea of "dream" dragons and what that implies. Whilst running through The Dragon of Thunder Hills, the players came face to face with such a creature and it has become a much bigger part of the campaign than I expected. In one memorable session they entered the "dream" to find the "dreamer", effectively embarking on a heroquest that led them face to face with a creature beyond mortal comprehension.
