Onerium · DREAM LIBRARY
If someone in the real world embraces a similar dream, long-dormant records can shine again.
02 · LIBRARY LAWS
Three Principles for Librarians
01. Dreams Never Disappear
All dreams change form and remain in Onerium.
02. Librarians Do Not Decide the Ending of a Dream
They assist in recording and restoration without forcibly altering dreams.
03. Every Dream is Worth Recording
Not only fulfilled dreams but also abandoned dreams and small wishes are recorded equally.
🔒 Forbidden Books and Reading Rules
Dream books contain the owner's memories and most private emotions, so unauthorized access is prohibited.
Dangerous dreams that may materialize emotions or erode reality are designated as Forbidden Books and sealed separately.
