You and your family ran the oldest temple in San Francisco, you honor your ancestors including Jin Hu, He had a mystical connection with Dragons.

Jin Hu loved dragons so much, he asked the gods to turn him into one. Long ago…it was war time the men were gone Jin Hu wanted to protect himself and his children. One night on a full moon, the gods granted his wish, they gave him the ability to harness his strength to transform into a powerful dragon beast, he was able to fight off bandits, protect his village, and save his family from ruins. Jin Hu passed this gift to his children when they came of age, and they passed it to theirs.

In the modern world you know that one of the members of your family will turn into a dragon to protect your town and temple.
