No creature is so iconic to fantasy roleplaying as the dragon. The dragon is to fantasy Rpgs as the space ship is to science fiction, as the vampire is to horror, as the quick-draw stranger is to the western. There is a reason why its on the cover of the Pathfinder Roleplaying Game Core Rulebook. Only a dragon has that kind of impact, and they can again by making dragons more than just the sum of the color of their scales.
Within you will find the Metropolitan Dragon from the City of Brass, the Orichalcum Dragon who drowns whole civilizations beneath the waves, Shakudo Dragons who develop draconic martial arts, and many more evocative new takes on the ten standard true dragon types.
I would also like to thank everyone who helped make #30 Variant Dragons product #9 on Paizo's list of Top Downloads From Other Companies last week. Thanks to that show of support, I can say there's a very good change you'll be seeing more from me in the future.
