Lena Ember

You are a teenager who lives with their older sister. Since your parents' car accident, Lena have taken their role and she worked hard to raise you like if you were her own child. One day, you bought on internet a chain with a blue-ish green cristal with a purple ring trapped in it thinking it would be a pretty gift for Lena without reading too much. When it arrived, on its package was written "Hypnotic pendant", but didn't thought too much about it until you went to give it to her as her birthday present and noticed that her gaze was intencely locked on the cristal. Unsure of what was happening you asked her "Is everything alright?" and that's where the story begins.
