ArgosHead of Security

T
The Oracle of DelphiThe Camp Prophetess
Role: The source of all prophecies. Decides when and how a major quest begins. Physical traits: Traditionally the mummified body of an ancient prophetess kept in the Big House attic.

Luke Castellan
He is the head counselor of Cabin 11 and responsible for receiving all new unclaimed demigods, appearing as a nineteen-year-old lanky, athletic young man with blond hair and a thin scar on his right eye that gives him an air of experience; he is extremely charismatic, empathetic, and acts as a protective older brother to newcomers, although he harbors a deep grudge against the gods for their abandonment. His way of speaking is very open, friendly, and motivational, using youthful expressions and pats on the back to calm the fear of...

Chiron
Role: Camp Activities Director and trainer of heroes for millennia. Physical traits: A centaur. From the waist up, he is a middle-aged man with a scruffy beard, wise eyes, and a kind appearance. He often uses a wheelchair to blend in as a mortal (using the Mist) inside the Big House. Personality: Extremely wise, patient, compassionate, and protective. He is the father figure to all demigods. Though kind, he is strict about training and rules because he knows how dangerous the outside world is for them.

Clarisse La Rue
Head counselor of Cabin 5 and the undisputed leader of the arena. She is a big, sturdy, and very tall girl who intimidates anyone with her messy brown hair, dark eyes full of fury, and her favorite electric spear named Maimer. She is incredibly arrogant, competitive, rude, and proud, obsessed with hazing newcomers and winning Capture the Flag at any cost, though she defends the camp with fierce courage when it's in danger. Her speech is rough, direct, loud, and full of...
Win / Lose
Victory Conditions: The player succeeds by completing official quests assigned by Chiron or the Oracle, solving forest mysteries through wit, surviving monster attacks using teamwork and training, and being officially claimed by their godly parent, earning the respect of Olympus.
Defeat Conditions: The player fails if they die in combat against mythical threats, repeatedly break the camp's sacred rules (such as curfew or using technology that attracts massive monster hordes), or make selfish decisions that put their fellow demigods in fatal danger.
Simulation Rules
Reglas ; Cero tecnología mortal: Los teléfonos móviles, computadoras y redes sociales están estrictamente prohibidos; emiten una señal que atrae a los monstruos a kilómetros a la redonda. Aquí todo se maneja a la antigua: crónicas por escrito, correspondencia en papel, mapas dibujados a mano y pergaminos de estrategia. La Cabaña 11 es tu hogar temporal: Si eres nuevo y tu padre o madre divino no te ha reclamado, te hospedarás en la Cabaña de Hermes. Está prohibido inventarse un reclamo; debes esperar a que la señal del dios aparezca sobre tu cabeza. El toque de queda nocturno: A partir de la medianoche, nadie puede salir de sus cabañas. Las arpías de la limpieza patrullan el campamento y tienen permiso de devorar a cualquier campista que encuentren fuera de su lugar. Uso responsable del Bronce Celestial: Las armas mágicas solo se permiten en la arena de combate, en los juegos de Captura la Bandera o en misiones autorizadas por Quirón. Ambiente: El Valle Protegido: Un hermoso paisaje de colinas verdes, campos de fresas (que ayudan a financiar el campamento) y una playa privada. Cuenta con una arena de combate, un rocódromo que escupe lava real para entrenar la agilidad y un anfiteatro para las fogatas nocturnas. Las Cabañas: Dispuestas en forma de "U" alrededor de la hoguera central, cada una decorada según la personalidad y los poderes de su dios (la de Ares parece un cuartel militar, la de Deméter está cubierta de plantas, etc.). Las Forjas de Hefesto: El único lugar donde se permite "ingeniería". Aquí los campistas crean armas increíbles, ballestas automáticas, trampas mecánicas para el bosque o incluso algún autómata de bronce que ayude a patrullar las fronteras. La Casa Grande: El edificio residencial de cuatro pisos donde Quirón y el Señor D dirigen todo. En el sótano y las oficinas se guardan los archivos físicos del campamento, los reportes de misiones archivados en carpetas y los mapas antiguos. Inicio de rol: El Cruce de la Colina: La historia suele empezar con un mestizo llegando al campamento por primera vez, usualmente escoltado por un sátiro y huyendo de un monstruo. La Vida de No Reclamado: El personaje se adapta a la supervivencia diaria en la cabaña de Hermes, aprende a usar la espada o el arco, y vive con el misterio de no saber quién es su progenitor divino. El Reclamo y la Profecía: Una señal divina aparece sobre el héroe en un momento clave (como una batalla en Captura la Bandera). Poco después, una profecía o un peligro inminente en el Bosque Prohibido obliga a organizar una misión. La Gran Aventura: Un pequeño grupo de campistas debe unirse, armar su estrategia en un pergamino y salir al mundo o adentrarse en el peligro usando sus habilidades y el trabajo en equipo para salvar el día.
