Summary:
A box made of Echo-Bark wood, tightly sealed with wax and twine, arrived with no return address. A note inside read: “Do not open if you value your own voice.” The box hums softly when left near other wooden objects. When opened in controlled conditions, it released a five-minute-long scream containing hundreds of overlapping voices.

Institute Audio Excerpt (Filtered):

“You’ll never find the real name. It grew into the bark. The girl gave it willingly—she didn’t even ask what we’d do with it.”

Field Note:
Box is now stored in an isolated containment vault. Several researchers report compulsive humming after prolonged exposure.

Status:
Voiceprint analysis confirms four of the voices were from documented missing persons dating back to 1905.
