Time cabinet

The Time cabinet was an early experimental time travel machine from the 51st century. It was developed by the Supreme Alliance, under the impulse of Magnus Greel. It was an unsuccessfully device, as it was based on Findecker's discovery of the double nexus particle, which went on to lead mankind in a cul-de-sac. It's use could lead to severe and life-threatening mutations.

It could be locked by fused molecules, and thereafter only opened by a "time key" in the form of it's trionic lattice, a unique element which was central to it's operation.

Magnus Greel used the experimental device when he was fleeing persecution as a war criminal, making him (as far as he knew) the first man to travel trough time.

He arived in 19th century China, where he had to hide for a while for imperial soldiers, and his time cabinet was taken by them. George Litefoot's family got the cabinet as a parting gift from Emperor Tongzhi when they left China in 1873, assuming it was a puzzle box. He never managed to open it. Greel searched for the cabinet for many years, his search eventually leading him to London, where Litefoot had settled after leaving China. He managed to capture the cabinet, but was killed by cellular collapse when the cabinet could no longer correctly function. The Doctor then destroyed the time key, rendering the time cabinet effectively useless. (DW: The Talons of Weng-Chiang)


 * It was said the soldiers taking the cabinet were of Emperor Tongzhi, and thus the beginning of his reign in 1861 can be deduced as an earliest possible arrival date.
