Summary
OLD TALE

In the beginning, the myriad stars crystallized into a form known as the "Star Jewel". The gem contained the power to grant any wish. People prayed to the Star Jewel for blessings, and obtained joy and fulfillment in their lives. People prayed to the Star Jewel for evil purposes, and brought about calamities. People grew covetous of the Star Jewel, breeding hate and resentment. The Star Jewel That had granted millions of blessings, had instead became the vessel for millions of curses. A singular existence, the "Guardian of the Star Jewel", prayed for the Star Jewel to be sealed away. The wish was granted, and the Guardian fell into an eternal sleep.

The Star Jewel could no longer hold its form and split into six fragments. A single massive planet became six. On the verge of slumber, the Guardian mustered the last of their strength, creating a being to oversee the world in their place. To journey across the heavenly bodies, watching. The "Observer of the Stars" bore witness to countless moments, countless stars, and countless lives.

 世界のはじまり、星々の結晶が集まり、<星玉>が生まれる. その石はいかなる願いも叶える力をもつ. 人は、星玉に願いを捧げ、幸福な暮らしを手に入れる. 人は、星玉に悪しき願いを捧げ、災いをもたらす. 人は、星玉を巡り争い、憎しみ合う. 幾億の願いを捧げられた星玉は、幾億の呪いをもたらす石となる. 唯一の存在である<星玉の護り人>は、星玉を葬るため願いを捧げる. 願いは叶う、護り人の永遠の眠りと共に. 星玉は、力も持たない六つの欠片となり、一つの大きな星は六つの星へとわかたれる. 護り人は眠りにつく間際、最後の力を振り絞り、自身の代わりに世界を観測するモノを生み出す. それは星々を巡り、観測する. <星の観測者>は幾千の時を、星を、人を巡るーー
