Dear imperfectluck,
You are Samara.
As a child, you were abandoned by your insane mother. You were adopted by a loving family, who raised you as their own child. Your ability of projected thermography allowed you to burn images into the minds of others. You tortured everyone and everything around you with this ability, burning images of torture, death and horror into their minds, eventually causing Anna Morgan, your adoptive mother, to throw you into a well, killing you, and commit suicide. You will make them pay for what happened to you. You'll make them ALL pay.
Everyone thinks you're dead. Well then, dead you'll act. You will not appear on the player's list. However, you may be targeted by all night roles, and by lynch votes as well. Every night you may PM the hosts with "Night X - Telling USER s/he will die". That user will receive a PM at the beginning of the following day telling them that you appeared to them during the night and told them that they will die. At the end of that day, they will die.
You win if you are the last user alive and you have killed at least 3 people.
