[@OneWayOut]; the legacy is another God or Goddess along your character's family line- this could be as close as their parent, or as far as their great-grandparent. The legacy has an impact on your character in one way or another, whether it be something like their looks, powers, personality, ect.

So for example, my character Ky' vie, her legacy is the Goddess of beauty, so it has an impact upon her looks; her skin is always clear and blemish free, any scars she gets heal so well that unless they're known about, they can barely be seen, ect. Whereas, with my other character Erin, her legacy is Nemesis, and she has an impact on her personality; meaning she has a twisted sort of sense of justice.

Other examples are Ghost's character Hawley, and my character Octavia; both of them might be children of Hermes, but each of them have a different legacy. Hawley's legacy is Athena, meaning he is extremely intelligent- whereas Octavia's legacy is Ares, he impacts on her personality and powers, meaning she's very war-driven and a great fighter.

But aside from all that; not all characters need to have a legacy. It is not a necessity, but more of an optional thing. :'3
