In the aftermath of the Great War, Germany was compelled to make reparations to the United States. Among its secret undertakings was the LowenHerz, a decommissioned German submarine tasked with transporting gold bars, priceless art, and advanced technology. Many of these treasures, however, never reached their intended recipients, instead falling into the hands of corrupt politicians and criminal syndicates.

On its fateful third voyage, the LowenHerz vanished without a trace, presumed lost to an unforeseen technical failure. Due to the sensitive nature of its cargo, no official records documented the U-boat’s transatlantic mission. Its disappearance was quietly erased from history.
