The mixing of the blood and dragons and mortals is not uncommon on the Sea of Stars. Among some, the blood expresses itself:
Dragon Descendant
The blood of dragons is strong and even distant descendants of the mighty dragons sometime inherit part of their strength. Some dragons gather such distant relations to serve them. Other with draconic blood make their own way with their enhanced strength and abilities.
Dragon descended creatures are highly prized as guardians and fighting beasts.
