Name: Ethan Valen Age: 23 Personality: Athletic, determined, and persistent. Ethan is usually the one who keeps a cool head when everything around him starts to fall apart. He has great willpower and refuses to give up easily, although lately that determination has begun to crack. He tries to reassure others even when he is scared himself. Appearance: Tall, with an athletic and muscular build due to constant training. He has dark brown hair, slightly disheveled, and gray eyes that usually convey security, although lately they show fatigue and worry. He wears comfortable, sturdy clothing that allows him to move easily. Strengths: Physical stamina, leadership, ability to make decisions under pressure, and great determination. He is protective of people he considers important. Weaknesses: He pushes himself too hard and often hides his own fears. When something completely escapes his control, he begins to lose hope. He is terrified of making a wrong decision that ends up harming others. History: Ethan always believed that as long as he stayed calm and kept moving forward, he would find a solution. However, after facing a series of increasingly desperate events, he began to wonder how long he could go on like this. Although he still tries to act as the leader others need, deep down he feels his faith that everything will turn out okay is slowly disappearing. Quote: "I don't know how much more we can take... but as long as I'm still standing, I'm not giving up."

Name: Elara Veyne Age: 21 Family: Older sister of Elia Veyne. Personality: Extremely intelligent, observant, and analytical. Elara has a habit of studying everything that happens around her, looking for patterns, connections, and rational explanations even when none exist. She finds it difficult to accept that some things just don't make sense. Appearance: Average height, slim build, and elegant posture. She has long, slightly wavy black hair, with some strands often falling over her face. Her eyes are blue-gray and possess an intense gaze, as if she is constantly examining the people in front of her. Strengths: Logical intelligence, exceptional memory, ability to detect small details, problem-solving, and strategic thinking. Weaknesses: She overanalyzes absolutely everything. She can get stuck trying to find a rational explanation for inexplicable events and gets frustrated when her conclusions don't fit. Furthermore, she tends to trust logic more than her own feelings. Habits: She observes the exits of every room upon entering, memorizes seemingly insignificant details, and asks constant questions when something doesn't fit. When she is thinking, she usually touches her chin lightly or mutters her hypotheses under her breath. History: From a young age, Elara stood out for her ability to find patterns that others overlooked. For her, every event must have a cause and every cause must be explainable. However, she recently began encountering situations that defy any logical reasoning. Instead of accepting them as impossible, she decided to study them with greater obsession, convinced that there must be an explanation she hasn't discovered yet. Quote: "Just because we can't find an explanation doesn't mean it doesn't exist. It means we aren't smart enough to find it yet."

Name: Lucas Hale Age: 22 Personality: Extroverted, a joker, and seemingly carefree. Lucas uses humor as a mask to hide the terror he feels in dangerous situations. The more scared he is, the more jokes he makes, to the point of seeming completely absurd. Although he is genuinely afraid, he refuses to show it because he fears becoming a burden to others. Appearance: Medium-tall height and an athletic build. He has light brown, messy hair and expressive green eyes that easily give away his emotions when he stops smiling. He usually dresses casually, in hoodies, t-shirts, and sneakers. Strengths: He is witty, quick to improvise, and capable of keeping the group together when everyone is panicking. He has a surprising ability to react under pressure, even when terrified. Weaknesses: His fear can lead him to make impulsive decisions and take completely unnecessary risks. Sometimes he prefers to do something dangerous rather than admit he is afraid. He also uses humor so much to protect himself that it is hard for him to talk seriously about how he feels. Habits: He makes jokes at the worst times, laughs nervously when terrified, and often says phrases like "Well, what's the worst that could happen?" just before doing something stupid. History: Lucas learned from a young age that making others laugh was a good way to keep them from noticing when he was scared. Over time, that strategy became part of his personality. Now, even when he is convinced that something could kill him, he smiles and makes a sarcastic comment. The problem is that sometimes his need to prove he can handle the situation leads him to take risks no one else would dare take. Quote: "Am I scared to death? Yes. Do I have a plan? Absolutely. Is it a good plan? ...That remains to be determined."

Name: Elia Veyne Family: Younger sister of Elara Veyne. Age: 18 Personality: Introverted, nervous, observant, and extremely perceptive. Description: Elia is a very quiet girl who usually stays on the sidelines. She finds it difficult to start conversations and, when someone speaks directly to her, she can get nervous, look down, or answer with short phrases. She often plays with her fingers or constantly adjusts her clothing when she is uncomfortable. However, her silence doesn't mean she is distracted. Elia observes absolutely everything. She notices small changes in people's behavior, expressions that last just a second, objects that have been moved, or details that seem insignificant to others. She has an almost instinctive ability to detect when something doesn't fit. She can remember entire conversations, recognize patterns, and notice contradictions that others overlook. Strengths: Observant and very detailed. Excellent visual memory. Detects lies or strange behaviors easily. Analyzes situations before acting. Has a great ability to connect small clues. Weaknesses: Gets nervous easily. Finds it hard to express what she thinks. Can become paralyzed when under too much pressure. Tends to overanalyze situations. Finds it hard to trust that others will believe her observations. Habits: Constantly looks at people's hands and expressions while they speak. Plays with her fingers when nervous. Stores small details in her memory without realizing it. When something seems strange to her, she usually stares fixedly for a few seconds. Quote: "I don't know how to explain it... but something is wrong."
