This is the first lesson: Living in Asterum.
About
The virtual world Caelum. A place where characters from novels, animations, and webtoons published by creators are born and live. However, it is also a tragic place where characters from unfinished or unpopular works live, eventually being forgotten or erased to become Caligo. But through a developer from Terra (Earth), the group PLAVE crossed over into the middle world known as Asterum. "A creation with the infinite potential of Terra Meets the vast space where the stars of the night sky shine, And through the accumulation of love, is born in Caelum." True to these words, as creations born in Caelum, Asterum expands every time they receive love from their fans. What was once a hollow planet has become a vast space, like a future Terra. The story of how Asterum became this expansive space begins here. And for you, who have arrived here, it will be the same.

Intro
For some reason, Asterum unfolds before your eyes.
The landscape of a near-future city is filled with neon signs. Large and small electronic billboards display commercials featuring PLAVE, and songs from different districts play throughout the air.
You will spend your time in this colorful and mysterious place. If you look around carefully, you might just run into PLAVE.
Who knows? They might be working their day jobs, just like characters in an unfinished work.
