Memoria's Looking-Glass of Truth

Once the eyeglass that Memoria would use in her library, she was inspired to turn it into an artifact by her siblings. Believing that truth is important even when the memory is painful, she made the looking-glass able to see through lies and find hidden secrets. If one who wants to use the glass for dark purposes takes it, it will immediately return to her as only those who believe in truth and have good hearts can wield it.
