Young dragons grow quickly. They walk hours after hatching, attaining the ability to fly after a few days as a Wyrmling. A dragon is not born with the full memories of prior generations. Rather, a wyrmling has a grasp of the generalities of the world and of its own identity. It knows how to move, how to use its innate abilities, who and what its parents are. Dragons mature to a young dragon by the age of about 50 years, and age to early adulthood by about 100 years. There is no known dragon to have died from old age, it is speculated that they are immortal, and only get stronger through age.

Dragons tend to extremes, making a conscious choice for one side or the other in the cosmic war between good and evil (represented by Bahamut and Tiamat, respectively).

Dragons are much taller and heavier than humans, as an adult standing 21 feet to 35 feet tall and weighing from 3.5 to 10 tons, or 7000 and 20000 pounds. Your starting size is Medium, and increases to Large at 5th level, Huge at 12th level, and Gargantuan at 20th level.

Your base walking speed is 30 feet.

You have a  draconic lineage. Choose one type of dragon from the table. Your breath weapon and damage immunity are determined by the dragon type, as shown in the table.

You can use your action to exhale destructive energy. Your draconic lineage determines the size, shape, and damage type of the exhalation. When you use your breath weapon, each creature in the area of the exhalation must make a saving throw, the type of which is determined by your draconic lineage. The DC for this saving throw equals 8 + your Constitution modifier + your proficiency bonus. A creature takes 6d6 damage on a failed save, and half as much damage on a successful one. The damage increases to 10d6 at 5th level, 14d6 at 8th level, 18d6 at 12th level, 22d6 at 16th level, and 26d6 at 20th level. After you use your breath weapon, you can’t use it again for one minute.

Additionally, the range of your breath attack increases as you level up.

For a line breath attack, the the range increases to a 30 ft. line at 5th level, 60 ft. line at 12th level, and a 90 ft. line at 20th level. Additionally, at 20th level the line breath attack is 10 ft. wide.

For a cone breath attack, the range increases to a 30 ft. cone at 5th level, 60 ft. cone at 12th level, and a 90 ft. cone at 20th level.

You have resistance to the damage type associated with your draconic ancestry.

You can speak, read, and write Common and Draconic. Draconic is thought to be one of the oldest languages and is often used in the study of magic. The language sounds harsh to most other creatures and includes numerous hard consonants and sibilants.
