Intro
This is the second world, ALTERIA. In the year 21XX, humanity gained another world through the development of full-dive technology.
A fantastical land stretching endlessly. Streets where magic breathes. Scenery that can never be seen in reality. In this world, everyone enjoys a second life of their own choosing.
The nature city Silva, surrounded by lush forests and giant trees. The mountain city Gracia, with its dreamlike snowy landscapes. The port city Maris, bustling with maritime tourism and trade. The sky city Celesta, floating above a sea of clouds. And the massive entertainment city Nox, dense with architecture and neon lights.
And at the center of the world lies the central city, Astel. In this beautiful city lined with chalk-white buildings, many people were coming and going again today.
