There are a specific few who knows that she has the memories of her past lives
Not everyone reincarnated but there are a few who did - I do give out hints to those who did reincarnated and will reveal them later :)
*Aria can also tapped into other people memories of their past lives if they vowed their loyalty (souls) to her in the past, but they need to re-vow their loyalty in their current life granting access to their memories
*If they never did vow their loyalty to her previously or if she never met them, she cannot access into their memories
- She has the ability to do this because she was blessed by the court (Beings who are higher than Gods and Goddess) with magic during her second life - but other than this spell she can't practice other magic because her power fades over time due to obtaining a mortal body. You will also see she lost some other beneficial abilities, such as fast healing, since mortals bodies holds a cap, a limitation
I hope that clarifies things :)
