Lore - Artifacts - Obsidian Tuning Fork
From correspondence from Terzo Zeno to Jacques Troisseau:
... a black tuning fork of steel and obsidian. It is enchanted, and I have calibrated to resonate at a range of frequencies such that will nullify the full spectrum of perceivable sound for humans and the majority of known creatures. The range of effectiveness is approximately a 12 meter sphere from the artifact. It should prevent communication between the creatures that the professor mentioned in his letters. In a pinch, it may slow their progress. Be warned, however, that you yourself will not be able to communicate with anyone while the artifact is in use.
The turning fork is said to be in the possession of Professor Dover, but it may have been destroyed when the professor was swallowed by a giant worm.
