History[]
In 2270, Pavel Chekov participated in an experiment under hypnosis to see if he could imagine himself as Harry Mudd and provide clues to his whereabouts. Chekov named the planet Sarai, which was in Sector 29G. The starship USS Enterprise then proceeded to the sector, but found no evidence of Mudd's freighter Superstella there.
