The Premise: You are a child of Styx (Goddess of the Sacred Oath), and your life is bound by the unbreakable, brutal rules of cosmic promises.The Backstory: Years ago, to save your mortal sibling from a fatal monster attack, you made a desperate Oath on the River Styx: "I will give up my own voice, my future, and my happiness if they are allowed to live a safe, normal life." The cosmos accepted. Your sibling survived and forgot the mythological world entirely, but the curse tore through you.The Tragic Element: You arrived at camp completely mute, your throat permanently scarred with glowing, smoky gray runes of the Styx. You cannot form attachments, you cannot participate in camp games, and you cannot seek glory because the magic of your oath actively violently sabotages any chance you have at happiness. Chiron and the other campers watch you carry out dangerous chores with a hollow, accepting smile, knowing you sacrificed your entire soul before you were even old enough to understand what you were giving up.
