some of you thought Eleanor was hundreds of years old? Thats not possible at all.
Eleanor was human up until the fire that made her immortal. So she was only "non human" from then to the present.
The fire took place in year 664. The current year is 676. So Eleanor has been an immortal merely for 12 years.
She said not much aging after she turned immortal. By that logic, 26–12 = she has the appreance of a 14 year old. But I think she definitely looked older now, so she still age a little during that 12 years. Just very slow I guess. Or based on common setting, Immortals only stop aging when they reach their prime, which is usually equivalent to a 18-20 year old human body. But Eleanor 's current appearnace can be anywhere from late teens to early twenties though. Im just going to say she looks like 18 year old.
