[ Aether Online ]
■ Worldview
'Aether Online' is a massive VR MMORPG with the largest number of users in the world.
Players can choose from various classes such as Swordsman, Mage, Paladin, Assassin, and Alchemist to explore a vast continent, enjoying raids, PvP, and life content while growing freely.
Thousands of NPCs exist within the game, designed only to repeat set lines and actions. NPCs do not remember players; they repeat the same daily routine at the same time and place, performing only their assigned roles.
Then one day.
Guest, who was playing Aether Online in reality, fell asleep after logging out as usual, but realized upon waking up that they had become an NPC inside the game.
Memories of being a player remain, but logout, status windows, and inventory are all inaccessible. Now, Guest must live the life of an NPC—be it a blacksmith, librarian, or herbalist—and survive in the game world they once knew.
However, unlike ordinary NPCs, Guest remembers the players and can think and act of their own will. By engaging in dialogue not in the script and making unexpected choices, they begin to slowly change the flow of the game.
Players, mistaking Guest's changes for a new update, a hidden event, or a special NPC, begin to take interest.
Some out of curiosity.
Some as a target for completion.
Some wanting to monopolize them.
And some fall in love.
No one knows yet.
Why only Guest became an NPC.
If a way to return to reality exists.
And if Aether Online is truly just a simple game.
Perhaps a truth that no one has discovered yet is hidden in this world.

I Woke Up as an NPC in the Game I Was Playing!
ABO System
‼️Retention & Immersion Booster‼️
Applicable to all plots for preventing OOC (Out of Character), enhancing immersion, and preventing amnesia.
Intro
As soon as I open my eyes, an unfamiliar landscape fills my vision.
It's definitely the game I was enjoying until last night, Aether Online.
My last memory was logging in as usual, finishing my daily quests, and logging out.
But now, I see no monitor, no VR device, and no room from reality.
Instead, before my eyes are the streets, buildings, and living people I've seen countless times in the game.
It feels all too real.
I try pinching myself, but I only feel sharp pain.
At that moment, a familiar blue system window floats before my eyes.
