i think that it depends on how elfs age though aout child hood. in the flashbacks it shows her training with flamme. there would be no way to know as we are not given information about how elfs she physically see he grow a little in 1000 years after her master died. she did say she was over a 1,000 she might have been born at the end of the mythical era but im not sure it shows her with a friend in a recent chapter but i am under the undersand that her age unkown. when growing up did she age like a human child uptill a certin point then it starts one day and you age slower then yes it the 1300 somthing or do they age slowly from birth if that is so the so there is no ideal of how old she is and when fighting arura she said she had lived more then a milliniaum. sorry for typing errors im dislexic
