Hero of Madness [Progression Fantasy]

The only way to save humanity is to dive through the memories of the past. After the Great Calamity, humanity fled Earth and found a new home on a space station called Obelisk. But their time among the stars would not last long. With Obelisk dying, humanity developed a new technology—one that would allow them to dive into the memories of the past in hopes of awakening mana. But among them is one whose memories would bring back far more than just mana.
