Die Glocke (German for The Bell) was a secret Nazi scientific technological device built by Group 935 in the Der Riese Waffenfabrik. It's purpose was believed to generate free energy or create an anti-gravity field similar to flying saucers, though Doctor Edward Richthofen also applied the technology of Die Glocke for the creation of the Matter Transference Device and the Wunderwaffe DG-2.
Die Glocke is a metallic object said to be between 12 to 15 ft tall and about 9 ft in diameter, in the shape of a large bell. The device ostensibly contained two counter-rotating cylinders which were be filled with an extremely unstable radioactive mercury-like substance, violet in color. This metallic liquid was code-named Xerum 525 and was stored in a tall thin thermos flask a meter high encased in lead. Additional substances said to be employed in the experiments, referred to as Leichtmetall (light metal). Among these was thorium and beryllium peroxides, as well as the mysterious Element 115.
In a letter found in Gorod Krovi, it is revealed that Die Glocke research inspired new theories of time displacement and movement across dimensions in Group 935.
The Der Riese facility was disguised as a gold mine with a strange structure outside of it, dubbed as ‘The Henge’. This Henge can be seen in the map Der Riese, and shooting it is the first step in the Fly Trap Easter Egg quest. The Henge was the testing area for Die Glocke, which apparently needed a ton of electrical energy to use. When it was in use, it could only go for a minute or two before shutting itself off, and it gave off extremely large amounts of radiation. During its first use, several of the scientists working on it died, and the ones that didn't suffered memory loss, permanent metallic taste in their mouths, and sleep loss. Group 935 recognized the danger, and began to test its effects on plants, animals and toys. It was reported that after it's use, the test subjects decomposed into a blackish-purplish goo on the floor. Also, while Die Glocke was in use, some objects began to lift off the ground, propelled by some sort of anti-gravity field.
Using the scientific discoveries found in Die Glocke, Group 935 started working on a anti-gravity vehicle, similar to Vimañas and UFO’s. Doctor Edward Richthofen used the technology for creating the MTD and Wunderwaffe DG-2. An unintended result of Die Glocke was creating the first man-made zombie, something Doctor Ludwig Maxis later tried to exploit to deliver Nazi-Germany an undead army.
The secondary aim of the Bell project was to create vortices to capture Vril into plasmoid substances. This was reported successful. It was not possible during the war to put selected test-subjects into Die Glocke to receive Vril radiations directly (to enhance physical and cerebral structure and so create the new race of mankind) because of accretions of unidentified crystalline matter in the aparatus in operation. Die Glocke might also be the source where Group 935 gathered Vril from, for instance used to create the V-R11.
