From 1919 and many, many, many years before had problems with plagues and diseases. 2020 was when Covid really struck hard. In 2321 (figured it was close enough.) The ORION Project was first initiated. But poor results and lack of funds caused ONI to put the project on hold, and the five surviving test subjects were reintegrated into active service but died within a year from unknown causes. and in 2525, humanity first encountered the covenant. I think humanity really needs to be carful after every 101 years.
