Young dragonborn grow quickly. They walk hours after hatching, attain the size and development of a 10-year-old human child by the age of 3, and reach adulthood by 15. They live to be around 80.

Dragonborn tend towards extremes, making a conscious choice for one side or the other between Good and Evil (represented by Bahamut and Tiamat, respectively). More side with Bahamut than Tiamat (whose non-dragon followers are mostly kobolds), but villainous dragonborn can be quite terrible indeed. Some rare few choose to devote themselves to lesser dragon deities, such as Chronepsis (Neutral), and fewer still choose to worship Io, the Ninefold Dragon, who is all alignments at once.

 Dragonborn are taller and heavier than humans, standing well over 6 feet tall and averaging almost 250 pounds. Your size is Medium.

Your base walking speed is 30 feet.

You are distantly related to a particular kind of dragon. Choose a type of dragon from the below list; this determines the damage and area of your breath weapon, and the type of resistance you gain.

 You can use your action to exhale destructive energy. It deals damage in an area according to your ancestry. When you use your breath weapon, all creatures in the area must make a saving throw, the type of which is determined by your ancestry. The DC of this saving throw is 8 + your Constitution modifier + your proficiency bonus. A creature takes 2d6 damage on a failed save, and half as much damage on a successful one. The damage increase to 3d6 at 6th level, 4d6 at 11th, and 5d6 at 16th level. After using your breath weapon, you cannot use it again until you complete a short or long rest.

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

You can read, speak, and write Common and Draconic.

 You can see in dim light within 60 feet of you as if it were bright light, and in darkness as if it were dim light. You can't discern color in darkness, only shades of gray.

• You have advantage on saving throws against disease and being poisoned, and you have resistance to poison damage.
• You have advantage on death saving throws.
• You don’t need to eat, drink, or breathe.
• You don’t need to sleep, and magic can’t put you to sleep. You can finish a long rest in 4 hours if you spend those hours in an inactive, motionless state, during which you retain consciousness.

 You temporarily remember glimpses of the past, perhaps faded memories from ages ago or a previous life. When you make an ability check that uses a skill, you can roll a d6 immediately after seeing the number on the d20 and add the number on the d6 to the check. You can use this feature a number of times equal to your proficiency bonus, and you regain all expended uses when you finish a long rest.

Reborn suffer from some manner of discontinuity, an interruption of their lives or physical state that their minds are ill equipped to deal with. Their memories of events before this interruption are often vague or absent. Occasionally, the most unexpected experiences might cause sensations or visions of the past to come rushing back.

Rather than sleeping, reborn regularly sit and dwell on the past, hoping for some revelation of what came before. Most of the time, these are dark, silent stretches. Occasionally, though, in a moment of peace, stress, or excitement, a reborn gains a glimpse of what came before. When you desire to have such a dreamlike vision, roll on the Lost Memories table to inspire its details.
