So, I find that the easiest way that I can explain it is this: a Legacy is like a Godly Godparent. They help to bring something a little extra to the character in some way. This could be either in their powers, their personality, their skills, etc.

So with mine:
- Ky' vie's legacy is Aglaea, because of this, Ky is like crazy beautiful. Her skin never scars or blemishes, her hair is always lush and vibrant, and she's got like the perfect figure. <- this one is physical.
- Adeline's legacy is friendliness and welcoming; so that's exactly what Addie is. She's very friendly, accepting and welcoming to people, even when she hasn't met them; it's part of her nature. <- this one is her personality.
- Erin's legacy is Nemesis, and with that influence, Erin has a dark and slightly twisted sense of justice. Balancing the scales of right and wrong. It's why she'll defend her friends, but she'll do it in an... unorthodox way. She has a habit of trying to send bullies to the Underworld. <- again, this one affects her personality.
- Octavia's legacy is Hermes, now because of him, Tania is able to move slightly faster than a normal demigod. Her Agilty is also heightened. <- this one is affects her abilities and traits by giving her some.
- Katherine... uhm... well... her legacy is, well, I'm sure you saw who. Her legacy affects her personality. She's rather dominant when it comes to things like sex; she's very open when she flirts, and loves making someone get all flustered. She also has a slightly high sex drive; but its not crazy out of control. <- affects her personality and traits.
- Isaura's legacy is Boreas; for her, she got a power from him, so she's able to control the wind, and use it to fly. <- this one is physical.

I hope this helps o:
