In 2368, after Captain Jean-Luc Picard had been transported from the USS Enterprise-D to the surface of El-Adrel IV, Commander William T. Riker contacted a Tamarian deep space cruiser. He demanded from the first officer the return of the Enterprise-D captain and that holding him might be considered an act of war. To this, the Tamarian officer uttered this phrase to his bridge staff. (TNG: "Darmok")
