Named in part for Glastonbury Tor in Arthurian legend, the Glaston Knights are a group of elite Knightmare Frame pilots under the command of Gilbert G.P. Guilford. All five are the adopted sons of Andreas Darlton; their names are Alfred G. Darlton, Bart L. Darlton, Claudio S. Darlton, David T. Darlton, and Edgar N. Darlton. They dress in identical red uniforms and wear visors resembling the faceplate on "Gloucesters". The Glaston Knights pilot "Gloucesters" equipped with missile launchers, but switch to the newer "Gareth" models prior to the Black Knights' attack on Japan. Their middle initials spell out the consonants of the word 'Glaston'.
