Early History
Ismene was born sometime during the 1st Century BCE, also known as 100 BC. Over 2000 years ago, Ismene and her twin sister Amara were working as personal handmaidens for the powerful witch known as Qetsiyah, the progenitor of the powerful Bennett witch bloodline. While they were her handmaidens, Ismene's sister Amara fell in live with a powerful witch named Silas. However, Silas and Amara's love was forbidden as Silas was engaged to be married to Qetsiyah. Plus the fact that Amara, as well as Ismene, was just a mere servant and Silas was a wealthy nobleman. So their social statuses as well as social norms, left them incompatible.

Despite that, Ismene watched the two fall more in love with one another and was the only one who knew about their relationship; as they both trust Ismene. Ismene eventually found out about Silas wanting to become immortal with Amara when Amara came up to her and asked if she wanted to take the elixir with them. Amara stated that Silas was on board with it as he knew how important Ismene was to her.

One the night that Silas was suppose to marry Qetsiyah, Silas magically stole the Immortality Elixir that him and Qetsiyah were gonna consume after their vows. He then drank it with Amara and Ismene in the tent they had set up in the woods, thus they become the first truly immortal man and women. Qetsiyah felt betrayed after being left at the alter by Silas. so she tracked him down and discovered the tent he had set up. She found out his betrayal was even more worse than she thought initially, because not only had had he fallen for another woman, but it was her handmaiden Amara. And Amara's twin sister Ismene, who is also a handmaiden for Qetsiyah, was in on with Silas and Amara.

Felling angered as well as enraged and betrayed by Silas, Amara, and Ismene, she decided to create the cure for immortality, which was revealed to Amara before making Amara the anchor, faking her death, and desiccating her. When Silas and Ismene came back, Qetsiyah confronted them and offered mainly Silas the cure, promising that she'd forgive his infidelity with Amara and Ismene being in on the plot, if Silas were to spend the rest of his mortal life with her. She also made Silas and Ismene believe that she used another does of the said cure on Amara before killing her by staging their tent with blood and a human heart. After faking Amara's death, Qetsiyah was able to lure Silas to a remote island but not Ismene; as Silas made it possible to give her time to escape she she would face the same fate as Amara or anything similar.

Ismene doesn't know what happened after that and it's unknown if Silas or Amara told her after they reunited with one another.

Amara
Ismene was Amara's older twin sister. She supported Amara when Amara told her about her and Silas being together. Nothing ever broke the bond that Amara and Ismene shared, even when she was presumed to be killed by Qetsiyah after becoming immortal.

Ismene was, for a short time, reunited with her sister in 2011 after she was revealed to be the anchor to the Other Side and wasn't stone anymore. She tried to spend time with her sister but because she was the anchor, she had become but a shell of her former self. Still, Ismene cherished the time she had with Amara before Amara killed herself. Because of what happened to Amara while she was the anchor, Ismene has a very deep hatred for Qetsiyah.

Now, it can be assumed that Ismene and Amara are reunited in peace.
