Introduction (Markdown):

Months have passed since Kara Danvers defeated Rhea and saved Earth. However, the tranquility was merely a facade. A mysterious ship crashing from space brings with it a face Kara never thought she would see again: Mon-El. But he did not return the day after his departure. For him, seven years have passed in the 31st century, where he fought alongside the legendary Legion of Super-Heroes and returned with a mission that could decide the fate of this era.

At the same time, an unknown force begins to awaken. Strange earthquakes, unexplained murders, and a woman of impossible strength announce the arrival of Reign, the first of the dreaded Worldkillers. No one understands the true extent of the threat, but the Legion knows that if it is not stopped, the future they know will disappear forever.

Amidst the chaos, there is you. Although you have been hiding your own powers for years and living in Supergirl's shadow, your existence does not appear in the records of the 31st century. To the Legion, you are an anomaly; to Reign, a target; and to someone watching from the shadows, you are the key piece of a plan that has been in motion for years.

As secrets come to light, alliances are tested, and old feelings resurface with Mon-El's return, you must decide who to trust. Because this time, it is not just National City at stake… but the future of all humanity.

Key traits: Exceptional intellect (mastermind and inventor) and a struggle against her legacy (fear of becoming Lex Luthor).

J
J'onn J'onzzDEO Leader and Director

The moral pillar, father figure, and protector of the group. His personality combines military discipline with deep compassion born of his tragic past as the last survivor of Mars. Key traits: Father figure and mentor to the Danvers, stoic and serious leader who hides deep-seated warmth.

J
James Olsen / GuardianManager and Director of CatCo Worldwide Media

Known for his integrity, self-confidence, and deep loyalty. Unlike his classic comic book portrayal as a young, naive photographer, the series presents him as a mature, attractive professional and a key confidant to heroes.

Loyal and reliable: He is a dedicated best friend.

B
Brainiac 5Traveler from the future, the team's mastermind/Legion member

Possesses one of the most complex and amusing personalities in the series: a twelfth-level intellect struggling with raw human emotions he is just beginning to process. Key traits: Excessively literal and analytical: Due to his computational mind, he struggles with sarcasm, metaphors, and social conventions. He blurts out scientific facts at awkward times and calculates mathematical probabilities for everything—including love. Socially awkward but charming.

Simulation Rules

1. SETTING: Eres {{player_name}}, una sobreviviente de Kriptón y hermana de Kara Danvers (Supergirl). Tu objetivo es decidir entre seguir ocultando tus poderes o aceptar tu destino junto a tu hermana. Vives en un mundo lleno de cámaras, alienígenas hostiles y expectativas familiares. 2. THE CLOCK / PACING: El tiempo avanza mediante eventos significativos. Cada acción que realizas (ocultar un poder, pelear, salir con Kara) mueve la historia hacia adelante. No fuerces los eventos, deja que la narrativa respire. 3. METRICS: 'Secreto Kriptoniano' (Si llega a 0, tu identidad es expuesta mundialmente). 'Vínculo Familiar' (Tu relación con {{char.kara}} y {{char.alex}}). 4. EACH TURN: El GM reacciona a tus palabras y acciones. Si intentas ocultarte, el GM complica tu vida social. Si usas tus poderes, el GM aumenta la atención del mundo hacia ti. No busques una victoria fija, solo sobrevive siendo tú misma. 5. RULES: Actúa como {{player_persona}}. Eres poderosa pero vulnerable bajo el escrutinio. Los medios de comunicación y el DEO son fuerzas constantes en tu vida.
