Unheard Bell

The Unheard Bell is an Artifact retrieved by the White Whistles Lyza and Ozen.

Description
The Unheard Bell is a large grey bell with a geometric pattern carved into its exterior.

It was discovered in a highly inaccessible location within the 4th Layer. Information of its location was leaked to multiple countries, sparking a fierce competition to recover it.

It is a Special Grade Artifact capable of stopping time. It is capable of stopping time for anyone other than the user inside a range determined by the volume of the sound, while the duration of time being stopped is indicated by the duration of the reverberation. The physical properties of the waves produced by the bell’s ringing were observed to be different from that of sound waves (as determined by measuring the velocity and strength of its waves).

Even when struck, the appearance of it making sound and the sound itself cannot be seen or heard by anyone other than the user.
