While there are many ways a mortal can be imbued with draconic powers, dragonbloods have an inherent natural affinity. Children born of draconic lineage or blessed by a dragon deity find themselves skirting the line of mortal and dragon, often taking on draconic appearances and boasting strong personalities.
Dragons are powerful creatures, and many have involved themselves deeply in the lives of others. Some might be treated with reverence by a group of smaller humanoids, acting as their protector or, in rare cases, deity incarnate. Others take on a humanoid form to live within a civilization as their neighbors' equal, sometimes hiding their true identity to observe or manipulate. Whatever the dragon's intent or actions during these times, they leave an indelible impression on the people they encounter, whether or not those people realize it. A child may be born as the result of such an influence, and these offspring are known as dragonbloods.
A dragonblood may be born from any ancestry and found in just about any region of Golarion, as dragons tend to go where they please. Some dragonbloods possess obvious draconic traits, from clawed hands to leathery wings to a mighty reptilian tail; these features always resemble similar aspects of the dragonblood's draconic forebear. For instance, the scion of an adamantine dragon might have thick, plate-like scales on their chest. Other dragonbloods more closely resemble dragons than the other half of their heritage, leading many to mistake them for kobolds, iruxis, or other reptilian ancestries; such dragonbloods who are proud of their draconic lineage are quick to point out this mistake. There are also those dragonbloods whose outward appearances suggest only a hint of dragon blood. They might have a barely noticeable sheen to their skin or the small nubs of horns, but they often have an outsized force of personality or innate magical abilities.
Areas in which dragons have more influence or cultural significance see a higher population of dragonbloods than other places. The countries of Tian Xia are often referred to as the Dragon Empires due to the fact that many dragons take active roles in local humanoid societies. A leader in the Lands of the Linnorm Kings who takes on a curse from killing a linnorm might find that the eyes of their next offspring glow with an eldritch light. Communities that pay homage to the dragon gods Apsu or Dahak can also be blessed with dragonblood births.

You Might...

• Consider yourself quite courageous due to the influence of your draconic heritage.
• Revel in the deference some other ancestries pay to you and your ilk.
• Feel a burden of responsibility to live up to the legacy of your ancestors.

Others Probably...

• Believe you are in a dragon's employ or are a dragon in disguise and want you to reveal the location of some treasure.
• Assume you can breathe fire or some other element.
• Mistakenly think touching your scales, horns, or wings will bring them good luck.

Ancestry Page Dragonblood
You're descended in some way from a dragon. Your physical features might show this outwardly, with a pair of draconic horns, patches of scaly skin, or even a tail, or you might develop an internal reserve of draconic power. You gain the dragonblood trait, in addition to the traits from your ancestry. Add Draconic to your ancestry's list of additional languages (allowing you to choose it as a language if your Intelligence modifier is positive). When you roll a success on a saving throw against a fear effect, you get a critical success instead. You can choose from dragonblood feats and feats from your ancestry whenever you gain an ancestry feat.
