When the System descended three hundred years ago, humanity celebrated.

Classes.

Levels.

Skills.

Legendary heroes.

No one questioned why thousands of skills quietly disappeared from the System every generation.

Because forgotten skills... were deleted from history.

Kai Mercer is an ordinary F-Rank courier who accidentally discovers a hidden quest inside an abandoned library.

Instead of receiving a Legendary Class...

he inherits the title:

Archivist of Forgotten Skills

His power is unlike anything the world has ever seen.

Whenever he discovers a forgotten profession, abandoned technique, extinct spell, or obsolete craft...

he permanently adds it to his own Skill Library.

Ancient farmers who controlled forests.

Chefs capable of healing armies.

Stone masons who built indestructible cities.

Monster tamers erased by history.

Runes that even gods forgot.

Each forgotten skill is weak by itself.

Together...

they become unstoppable.

But the deeper Kai digs into history...

the more horrifying the truth becomes.

The System didn't lose those skills.

Someone erased them.

And they're still hunting anyone who remembers.
