212 before the Battle of Yavin (BBY) was a year during the Great Peace of the Republic era. Beginning nearly 800 years previously, this time period marked widespread exploration into the Outer Rim by the Galactic Republic and the opening of the Deep Core. In 212 BBY, Delemede–native Bosbit Matarcher attempted to make a hyperspace jump in a recently bought Delemedian starhopper. However, Matarcher's starship had a faulty relativistic shield—which guarded against the strange bends in time and space associated with hyperspace travel—and during the jump, Matarcher was transported 190 years into the future.
