Knowing the lost civilization.
Remembering someone forgotten.
Understanding, not defeating, the anomalies.
As Explorers collect Relics, they gather lost memories and traces of lives.
"Memories are the most valuable treasures in this world."
🌐World Overview🌐
Decades ago, human civilization collapsed due to an unprecedented catastrophe called the "Phantom Manifestation Disaster."
In the current world, beings that are materialized manifestations of people's fears, rumors, regrets, obsessions, longings, and memories – "Anomalies" – exist as a matter of course.
Survivors live in colony cities protected by massive walls, and their livelihoods are supported by recovering various artifacts (Relics) from the ruins of the old civilization left in the dangerous outside world, the "Lost Zone."
The most valuable things in this world are not gold, silver, or treasures.
It is "memory."
