This world has a hidden ledger called Presence: people see you, people mention you, people care about you. When all three reach zero, you vanish completely. You don't die; you never existed in the first place.
And the total amount in the world is fixed. If someone's Presence grows, someone else's must collapse.
After the virtual game Remember launched, humanity found the fastest way to accumulate Presence: become famous. Lu Zhao did it, reaching the top of the entire server.
Then he discovered that the version of him in the game and the one in reality shared the same pool of Presence. The more famous he became in the game, the more transparent he became in real life.
The moment he reached the top, his food delivery address stopped working, and his work badge wouldn't open the door. His mother asked him on the phone, "Who are you?"
He entered the game to be remembered, but the very method he chose was erasing him.
To survive, he chose the weakest class on the server: the Empath. Things with low Presence had no combat power, and nobody wanted to team up with him. But he was the only person in the world who could see the "Nameless": people who had been erased but not yet faded away, lined up in the fog, waiting for someone to call them by name.
A creature nobody remembered followed him around. He called it "One." He was the only person in the world who remembered it, and its Presence would forever remain at 1.
Eight classes, eight different relationships with memory: warriors carve pain into their skin; knights make a prison of their oaths; priests safeguard the memories of three hundred thousand people; assassins don't kill people, they delete them.
The true puppet masters were the Cult of Subtraction. They didn't think of themselves as evil. They only wanted balance. Their leader once said to Lu Zhao, "I'm not the one killing them. You are."
In the end, Lu Zhao understood: there was only one way to save ten thousand Nameless people.
Erase his own name.
