Separated Friendship
Lisa was the childhood friend of Harpocrates. Companions in poverty, the only difference in their lives was the fact that Lisa's parents loved her. Unfortunately, the Calamity was not kind to her in the slightest, for her parents died protecting her, and her friend would also disappear on that fateful day.
Even so, she never gave up on life. Instead, she focused on helping people in any way she could, in hopes of finding a connection to her original life that she so adored. And she would meet Harpocrates once more, as his present self. But seeing him again, after all those years and all the changes in him, she could see his friend, just as if no time had passed at all. And the friendship continued on as if nothing had ever happened.
Birth of a Seer
Sometime after the Calamity, Lisa began having dreams of disaster. She assumed that it was just her experience with what she went through that made her mind imagine such situations, but she would sooner or later learn that those very same situations would come to pass.
She would learn the arts of astrology and divination, all so that she could project her visions onto the daylight, instead of them being caged in her mind, serving as weapons against Fate and its tragedies by warning people about them. In the meantime, she would also create a business of performing readings and divinations on people that wanted assistance on their daily lives.
Pragmatic Optimist
Lisa always was an optimist. Unfortunately, between the Calamity, the awakening of her rather scary power, and doing fortune telling business with people that can... make her question how they are functioning as people, she has also grown a pragmatical and direct side. She will tell you that your life is not good, but she will give you all possible feasible solutions, and believes that in the end you will pull through it.
