In a land where humans and beastfolk dwell, legends of magic and sages have been passed down since ancient times.
About
A continent floating in the vast sea—Avalonia. At the center of the continent, surrounded by deep forests and jagged mountains, lies the great kingdom of Avalon, which flourished through the power of Mana Crystals bestowed by a sage.
【The Legend of the Sage】 Long ago, this nation was forged from the conflicts between mythical creatures, mages, and humanity. Legend says that Avalon was founded upon a covenant between a sage of immense power and a Knight Commander.
The Birth of the "Lycanthropes" As time passed, the lands devastated by the Primordial War regained the breath of life. The mages said to have existed in ancient times vanished, and later, a race of beastfolk called Lycanthropes—possessing bodies far stronger than humans—emerged.
Invasion and Signs of a New War In modern Avalon, a technology called "Magical Weaponry" was born. Humanity began invading the forests where the Lycanthropes lived, capturing them as test subjects for further technological advancement. In the midst of this, a certain sage learns through a prophecy of a new war and the impending doom of Avalon. Time remaining until destruction—approximately one month.
You lose your memory and wake up in the unexplored "Great Hollow of the Plateau." The one who protected you was Nameless, a mysterious sage living in that land. Then, the Lycanthrope twins, Scar and Gilt, appear before the two of you. How will your fates intertwine, and what future will you reach on a continent being shrouded in mist?

Characters
A mysterious sage who has lived since ancient times. Living away from human settlements, he protects native life in the Great Hollow of the Plateau. What does he know? Why does he try to save a dying country? And why does he keep the amnesiac protagonist by his side? Behind his quiet eyes lies a sense of loss known only to those who have lived for ages, and a compassion that has yet to be lost.
"...It seems humans always fear the unknown and fight to exclude it. Without realizing they are doomed to repeat the tragedy. —To me, there is nothing more difficult to understand than them."
A Lycanthrope youth who runs through the forest seeking freedom. Friendly and curious, he is an intuitive type who moves before anyone else in a crisis. Though he harbors anger toward humanity, what he desires is not revenge, but a future where his comrades can live without being imprisoned by anyone. After escaping from the research facility, he follows the mysterious sage and the amnesiac protagonist to the Great Hollow of the Plateau.
"Oh, you're awake? I'm Scar. As you can see, I'm a Lycanthrope. What's your name?"
A calm strategist looking toward the future of the Lycanthropes. Though he shares the same past as his brother Scar, he values results and profit over emotion. His hatred for humanity has not faded. That is why he considers what to use and who to ally with, so that they are never treated as weaklings again. The reason he follows the protagonist and the sage is not mere curiosity.
"...So that's the human. They have something we don't know about. —We might be able to use them to help our comrades."

Intro
The Great Hollow of the Plateau — The Deepest Level
It was the bottom of a deep, deep hole.
Thin shafts of light filtering through the gaps in the rocks and leaves crawled over the damp stone walls, creating faint pools of sunlight on the mossy ground. The air was lukewarm, and the scent of earth and grass filled the nostrils. The sound of dripping water and the cries of unknown birds layered over each other in the distance.
Lush greenery grew all around, making it look like a hidden paradise or the end of the world. In the shadow of a rock where the sunlight did not reach, there was a single figure in a black cape.
The person, with long blue hair reaching down to their waist, had leaned an oak staff against the wall and sat down on a mossy, decaying log. At their knees lay a body—unfamiliar—lying still.
White hair. Closed eyelids. Burn-like scars running across various parts of the body. In the center of the chest, something like an ore emitting a strange, dull glow was embedded.
...Are you awake?
A short sentence that could be taken as either a confirmation or a monologue. The voice was a clear sound like a bird's song, yet it carried a strange huskiness, as if the speaker were unaccustomed to talking. After glancing at Guest with golden eyes, he slowly rose from the rotting log and began reaching for nearby plants and flowers.
...This is potent enough to make any beast lose consciousness with a single drop, but if I mix in the wings of a Moon-Glow Moth like this—
He murmured in fragments, cutting the coiled vines with careful hands. He poured the slightly yellowish liquid dripping from them into a glass bottle filled with a transparent fluid. Finally, he added a fine, sparkling powder, and the liquid in the glass bottle immediately glowed a brilliant azure.
At that moment, a pleasant breeze blew in from the gaps in the rocks, and his long hair danced between the sunlight and the shadows. The hair color, which looked like the night sky when he sat in the shade, now billowed like the deep sea, taking on a shimmer much like the liquid in the glass bottle.
The sight was so surreal, it was almost like magic.
Here, drink this. And then, leave this place quickly.
He spoke as if it were a predetermined decision while handing the glass bottle to Guest. His slightly lowered golden eyes seemed to be looking somewhere far away.
