So, I give you:
The Dragon Isles
Silver Dragon 1 & 2
Black Dragon drabble
maderr's Black Dragon
Red Dragon 1a 1b 2
Blue Dragon 1 & 2
and maderr's Black Dragon Drabble 1 and Black Dragon Smut
Silver Dragon and Black Dragon smut are NC-17. Where's my summary for this series...
Far to the east lie the mysterious Dragon Isles - none have seen the creatures they are named for in so long that their existence is now naught but myth. A young man fleeing for his life reaches the Dragon Isles and what he finds will change not only his world, but everything the world has ever believed about dragons.
Note: This is set in the same universe as The Azure and Azure Seas, though those characters won't be making an appearance until Blue Dragon so if you haven't read them, it shouldn't make any difference.
