Use these tables to customize Dragons and make them unique to your campaign world.
Note: The first descriptor is regional and that's primarily up to you----It's your game, where are they from? Real-world regional examples are: English, Mongolian, Scandinavian, Saharan, Pacific, Carpathian, Himalayan, Atlantic, etc. The first table has generic regions if you prefer. Choose which tables to roll on or roll on them all. Don't be afraid to re-roll results you don't like. In a matter of moments you should have something much more interesting than say, blue.
Results will look something like this:
Desert Gray Razor-Back (similar to a Young White, +2 Hit Dice; breathes an Acidic Cloud, animal-intelligence, chaotic, hoards only coins, 400 years old, Lairs in Ruins.)
Solamnian Yellow Mud-Mane (similar to an Adult Red, +1 Hit Dice; breathes Lines of Fire or Acid, average-intelligence, neutral, half the standard treasure, 700 years old, never sleeps, Lairs near Rivers.)
Coastal Copper-Fang (similar to a Young Green, -1 Hit Dice, breathes a Cone of Lightning, low-intelligence, chaotic, hoards only bones, 600 years old, has a tail like a Manticore, Lairs in a Swamp.)
