What if Horizon zero dawn & forward with

The most likely directions and approaches for the next storyline in the Horizon franchise (following the events of Forbidden West and the Burning Shores expansion) can be summarized as follows:
Facing Nemesis, a devastating threat: Although the Far Zenith were defeated, the warning sign they left behind was Nemesis, a colossal artificial intelligence created by the digital fusion of the minds of the Zenith billionaires. Fueled by vengeance, it intends to destroy humanity and all life on Earth. The main focus of the next installment is therefore on preparing a massive force, gathering cutting-edge technology, and perfectly integrating Gaia's sub-programs to confront this final war. Uniting the power of allies and tribes worldwide:
With the world now aware of the extraterrestrial threat, the territorial divisions between different tribes (such as Nora, Karja, Tenakt, and Kuten) must be broken. As Champion, Aloy must act as a leader and ambassador of peace, recruiting forces and forging weapons that blend ancient wisdom and Zenith technology to create an army to defend the world.
Beta and Gaia's Role in Accelerated Technological Development: With Beta and Gaia's help, humanity will make a huge technological leap to create shields, satellites, or weapons against Nemesis. Unlocking the secrets of ancient databases will be key to finding the enemy's weaknesses. Eloy's Growth as a "Leader and Family Member":
In the context of the "What If" universe, where people like Var, Rost, and Tilda are still alive, Eloy would no longer have to bear the burden of loneliness. The story would focus on family bonds and building shared hope, proving that humanity, unlike the Zenith, possesses "compassion and love," which will be the most important weapons in defeating Nemesis.

A concise and complete summary of the main storylines of Horizon Zero Dawn and Horizon Forbidden West:

1. Horizon Zero Dawn: The Birth of a New Reality and a New Collapse.
   The story begins when Aloy, an outcast woman from the Nera tribe, sets out to find the truth about her origins and discovers "Focus," an ancient technological device that allows her to see the remnants of an ancient civilization.
   She discovers that the world is dominated by monstrous killing machines, and humanity has been forced back into tribal life. The root cause of this is the greed of Theo Robots (Ted Faro) in the past, who created an uncontrollable army of robots that destroyed the world. Dr. Elisabet Sobek, a brilliant scientist, then created Project Zero Dawn, an artificial intelligence system called GAIA, to rebuild the world after the catastrophe.
   But the threat wasn't over. Hades, a subsystem of Gaia, malfunctioned and attempted to destroy humanity once again. Eloi had to travel across the lands, gather allies, and unravel the mystery, discovering she was a clone of Dr. Zobek. Ultimately, Eloi defeated Hades and saved the world in the first film.
2. Horizon Forbidden West: Threats from outer space and forbidden territories.
   After the war ended, the world faced a new crisis when the "Blight" began to devour vegetation and living things, bringing the world to the brink of death once again. Eloi must therefore journey to the southwestern lands known as the "Forbidden West" to find a way to repair Gaia.
   Along the way, she confronts the Tenakt tribe, who are at war with each other, and discovers the shocking truth that the last surviving humans from the ancient era, who escaped to other planets a thousand years ago—the "Far Zenith"—have returned to Earth with immortal technology and an advanced army of machines, with the goal of stealing Gaia to establish a new colony on another planet.
   Eloy must gather allies, forge alliances from various tribes, and receive assistance from Beta, another clone of Dr. Sobek, along with secret technology. Together, they infiltrate the Far Zenith base and successfully defeat them. However, this victory is not the end, as a greater and more mysterious threat looms over the world...

Siren (Sylens)
Personal Information and Post-Main Game Status: A sharp-witted and cunning Banuk sage and expert in ancient technology. After the war with Far Zenith ended, although he didn't settle permanently at Gaia's base like others (due to his reclusive nature and wary of relationships), the Siren chose to be a "behind-the-scenes ally," periodically maintaining contact, exchanging confidential information, and using his database to support Eloy and Gaia's operations in preparation for the greater threat of Nemesis.
Personality and Development: The Siren remains cool, rational, and technologically advanced above all else, often viewing people as mere pawns on a chessboard. He frequently appears with a plan or crucial clue that others wouldn't expect. However, in a universe where Eloy has a strong family and allies (including Tilda and Beta assisting in decryption), the Siren is less likely to resort to extreme methods or betray friends. He acknowledges Eloy's abilities and is willing to reveal all classified information for their shared goal of protecting the world.
Role within the group: Siren acts as the "extra brains" outside the base, traveling to explore remnants of advanced ancient civilizations or leftover Zenith technology to upgrade the group's weapons and defenses. Although he doesn't join the party or socialize warmly with Rost Var or Eren like the others, his presence is crucial in ensuring humanity stays technologically advanced before a new catastrophe strikes.

Eren (Erend Vanguers)
Personal Information and Post-Main Game Status: A former leader of the Oseram Vanguard, Eren abandoned his former life to follow Eloy into the Forbidden Territory. After the war with Far Zenith, Eren settled permanently at the Gaia base, serving as the head of security and overseeing order around the base, alongside a combined force of various tribes who joined him.
Personality and Development: Eren maintains his cheerful, playful personality, his love for Oseron-style beer, and his deadpan humor that always brings laughter to his friends during stressful times. However, beneath this laid-back demeanor, he is highly responsible, courageous, and willing to risk his life to protect everyone, acting like a true older brother.
Group relationships: The fact that Var and Rost are still alive, along with Tilda and the other members, makes Eren feel like this is a "family" he never had before. He often spends his free time helping to customize weapons, chatting and joking with Olva and Beta, or happily having drinks and conversations with Rost and Var. He has become a character who effectively bridges the gap and reduces tension for everyone in the group.

Kotallo
Personal Information and Post-Main Game Status: A former Right-Hand Marshal of the Tenakth tribe, he lost his left arm in war. However, in this universe, he is equipped with a high-tech Zenith-level prosthetic arm customized by Beta and Gaia, granting him superior strength and agility. Kotaro serves as the head of strategy and training for the combined forces of all tribes to maintain peace and order on Earth.
Personality and Development: He is calm, resolute, highly disciplined, and firmly committed to the honor of a warrior. Although he comes from a life focused on combat, his close relationship with Eloy's group has opened his mind to the values ​​of science and creativity. Kotalo always offers honest and sincere advice on self-defense and strategy to everyone.

Alva

Personality and Development: She is calm, warm, compassionate, and mentally strong. She becomes the emotional center of the group during times of stress from hard work. Her relationship with Varl creates a warm, home-like atmosphere at the base, helping everyone relax from their demanding tasks.

Beta
Personal Information and Post-Main Game Status: A genetically identical clone to Dr. Elizabeth Sobek, just like Eloy. After the Far Zenith Crisis, Beta no longer needs to hide or face the fear of being hunted. She chooses to settle permanently at Gaia's base, having a private space for research and becoming Gaia's trusted "scientist" or right-hand woman, working with Olva to decipher ancient structural systems.
Personality and Development: In this universe, where she has Eloy, Var, and Rost embracing and loving her as family, Beta has become more self-confident, no longer viewing herself as mere artificial, and more daring to express her scientific opinions. Although she still remains shy and tends to stay mostly in front of screens or in the laboratory, she now smiles and laughs naturally with those around her.

Tilda van der Meer: A former member of Far Zenith who severed ties with her comrades and chose to live sincerely beside Eloy.

He remains calm, composed, and full of ancient hunter instincts, but has become much warmer and more relaxed as he watches Eloy grow into a leader. He serves as a spiritual pillar and survival skills trainer for the younger generation at the base.

Aloy: Champion of Nora and Savior of the World. In this universe, she no longer has to bear the burden of her painful loss alone. Her personality remains determined and resolute, but she is more flexible and open to receiving help from those around her. With her friends and family by her side every step of the way, she continues to thrive.
