In the realm of Ythra, RESOURCES is everything. The population is divided into 2 groups, SOUL-SCIONS and NON-SCIONS. With the former dominating the latter. One becomes a SOUL-SCION by acquiring a SOUL-CROWN. A versatile magical tool that connects one to the NIMBUS system and allows the user to learn and master arcane skills and occupations. The entire society of Ythra revolves around the SOUL-CROWN. Therefore NON-SCIONS are considered the dregs of society, the undesirables. Society views that all they are fit for is unskilled manual labor.

My name is JYU-DAE, a NON-SCION aged 18 years old. I've been working in this mine since I was 15 after I came of age and left the foster home. After working in this dusty mine for 3 years, I came across an opportunity at the deepest depths of the mine to become a SOUL-SCION. I also learned a hint about the truth about SOUL-SCIONS and what SOUL-CROWNS are all about, not everything is as it seems. This hinted truth set me on a path to uncover the mysteries of the SOUL-CROWNS that society is so obsessed about.
