Grentburg Entity

The Grentburg Entity, a photo taken in 1891 shows the Grentburg Entity, an entity found in an abandoned factory in Grentburg. It was not found again after the photo was taken, everybody who goes in that factory disappears.

Police prevent anybody from entering.

The factory is planned to be torn down in 2030.

The photo shows a dark creepy room filled with clutter with a dark almost humanoid silhouette in the corner of the room, it is extremely unnerving and can make people sick by just looking at the image so the image is not on the slideshow for your own wellbeing.

The prevailing theories are 1: Balloon. 2: Mold or Rust patch. 3: Umbrella.
