Prologue

Guizhong. The goddess of dust, Rex Lapis' lover. He still remembers the day she gave him her "Memory Of Dust".

"A little something I made, so you can always remember what is most important to you. Think of it as a little storage box and a reminder of who you are! It's going to be very useful in the future."

Smart invention, Guizhong.

It did, in fact, become very useful in the unexpected future. A future that never meant to exist in the first place.
