In 2121, on Callisto,Saturn's father, the head of the Space Development Research Center (SDRC), died ten years ago in an unknown explosion at the building. Since then, the center has been left closed and unattended. But when Saturn turned 19 years old, his father's past colleague secretly invited him to enter the Space Development Research Center together. That’s where he found the data of 'project Hitchhiker' and 777 pairs of genesis sneakers. Much of the data was lost, but enough was left to continue the research.
XenoV, our universe, is the parallel universe of Dark Forest.
SDRC discovered 11 planets spread out in the space where VRIUM can be mined. But their location data got lost in the explosion, which is why exploration is such an important process in this project.
- VRIUM is a substance that does not exist in Callisto, and it is free to transform digitally.
- 777 pairs of personal space exploration sneakers using VRIUM were secretly developed, and wearing sneakers combined with VRIUM enables moving close to light speed in space.
