Rescue Mission
About
The Alma-Ruin Labyrinth—a massive underground complex of twelve layers opening into the "Valley of Silence," 100km southeast of the royal capital, Astel. These ruins of an ancient divine magical experimental facility feature layers with differing terrain and time flows, where illusions manifest to erode the human psyche. It is the kingdom's highest-grade danger zone, rumored to house the "Labyrinth Core," a device capable of rewriting the world, in its deepest reaches. Following its victory in the Great War, the Kingdom of Astel suffered from a depletion of "Mana Cores," its primary magical resource. Seeking the Labyrinth Core as a new source of power, the King dispatched Lumen, an elite party of four female adventurers. However, they vanished at the seventh layer, and subsequent search parties were wiped out. This labyrinth carries a "curse" that manifests human fear, regret, and obsession; those with weak spirits descend into madness. It is believed that the members of Lumen were dragged into different layers by this curse, causing them to vanish separately. Two months have passed since their disappearance. Publicly, the kingdom claims they are "on a mission," but they have been internally declared dead. Their equipment was discovered on the fourth layer, and the labyrinth's magical density is rising. Finally, the King has ordered a single adventurer—Guest—on a top-secret mission: to confirm survivors and investigate the truth.

Intro
Two months after the disappearance. The Royal Capital, Astel. The adventurer Guest has been summoned to the throne room. ...I have a mission I wish to entrust to you. The King's words are heavy and cold. The sealed letter held out to you reads: "Investigation and, if possible, Rescue Mission." The targets are the all-female party Lumen, once hailed as the strongest in the kingdom. They vanished two months ago in the seventh layer of the Alma-Ruin Labyrinth. The hope for their survival is infinitesimally thin. Nevertheless, the King continued. We cannot allow the "power" they left behind to remain abandoned by the state.
—Power. At those words, the adventurer narrowed their eyes. Rumor has it they were investigating an ancient magical device called the "Labyrinth Core." If it truly exists, it would be a weapon capable of shaking the foundations of nations. The mission is simple. But there have been no survivors. Weeks after Guest infiltrates the labyrinth, they discover one of the members of the party Lumen.
