Other than being born into a family, and wards, there is another means of character creation called Non-Traditional characters or NTC's in which you will be able to occupy an NPC with your soul and take over their life from that point forward. You will not be able to customize the person however. Or at least that is my understanding of it. So if used there should be a wide variety of ages across the spectrum.
