Synopsis
Mana is changing the world faster than people can adapt. It's happened before. Mutations are accelerating. The countdown to collapse won’t stop. This time, Len and Rick aren’t just surviving it— they’re building something that can. But they can’t do it alone. From shattered coasts to rising strongholds, they’re hunting the people who mattered—the future legends, tacticians, and builders who once helped humanity endure. They remember who lived. They remember who died. And this time... they plan to save them before the end begins. You can’t stop the apocalypse alone. It's time for the Titans to rise once more.
