The Book of Luna

From Megaman Mush Wiki

A Stardroid artifact that supposedly contains the collected knowledge of the Stardroid race. Belonged to the Stardroid Librarian, Luna, and said to hold a piece of her soul or programming, which is how it has its name.

This artificat originally turned up in the hands of Elegy, a former gravedigging robot who found the Book and began preaching the word of the Stardroids as a gospel. After Elegy's death, the book passed in to the hands of Dr. Light, who studied it to learn all that he could. It was apparently then stolen by Gemini Man, who claims to have sold it without reading or opening the book. Its current whereabouts are not known.

This artifact should not be confused with the Book of Luna written by Daryn Luna that served as a 'religious text' for the Bass Cult in Africa.
