Die Glocke

Die Glocke (The Bell in German), codenamed "Project Chronos", was teleportation device constructed by Nazi Germany as a Wunderwaffe during World War II, based on the designs of the Wyrresters. Its name was derived from its shape.

Initial transmission
The workings of Die Glocke were initially devised by the Wyrresters during ongoing population crises on their home planet Typholchatkas. Hoping to launch a military operation on Earth, the Wyrresters sent the instructions for building the machine as coded radio signals to the planet which was in the grips of World War II. The signals were intercepted by both Britain and Germany.

After they were translated, the Germans began constructing the machine. At the time, the war was going badly for Germany and desperation was mounting. An increasingly-delusional Adolf Hitler claimed aliens had sent the Germans a Wunderwaffe ("wonder weapon") to help him achieve victory.

Construction and testing
SS General Hans Kammler led the project at a test site in Wenceslas Mine (known as "the Henge" or "the Fly Trap") in occupied Poland, in the region of the Sudeten Mountains. Powered by hydro-electricity from a nearby dam and worked on by inmates from a nearby concentration camp, they built a stone circle, Stonehenge-like monument, as per the instructions and constructed the machine, marked with swastikas on the side.

In the first test of Die Glocke, all the scientists were killed by the mutagenic energy. Following the second test, five of the seven scientists died from exposure. The British later assumed that the Germans realised that their problems related to energy types and ley lines. Rumour had it that the SS continued the experiments on British soil, launching covert missions to Scotland to use suitable Neolithic structures. Whatever the case, little more was achieved with Die Glocke. It was used one last time to murder all the inmates who worked on it to keep it a secret and then transported with General Kammler by U-boat to a secret Nazi base in Neuschwabenland, Antarctica.

Allied agents in occupied Europe confirmed the existence of the German machine, prompting the British to construct their own version, codenamed "Project Big Ben". While initial tests were more successful, the British experiments ended in disaster on 21 March 1944 during the vernal equinox when the Wyrresters attacked. The Home Guard had the test site ravaged by the Luftwaffe to stop the attack.

Rediscovery
Professor Jason Clearfield, a pawn of the Wyrresters, spent the post-war years attempting to track down Die Glocke to replace the destroyed British Bell. Through contact with Neo-Nazis, he was able to track it down in Neuschwabenland and even gained access to the necessary Nazi gold to make the experiment financially viable.

In 2014, Clearfield transported Die Glocke to Ringstone in Wiltshire, where the British experiments took place. Because of damage to the original site, Clearfield created his own stone circle which was only sufficient to transport Wyrrester consciousness into another host, such as an insect, rather than transport their physical forms to Earth. The larger Wyrrester-controlled insects invaded Ringstone to prepare for their arrival.

The Twelfth Doctor, Clara Oswald and the British Army interfered before Clearfield could run the experiment during the next vernal equinox. Clearfield was accidentally sent to Typholchatkas as the Doctor shut the machine down. After the crisis was over, Department C19 arrived on the scene and transported Die Glocke away.
