Knight One (real name unknown) worked for a covert Earth organization. In 2258 he, along with Knight Two, kidnapped Jeffrey Sinclair to find out exactly what occurred in the time that Sinclair blacked out during the Battle of the Line. Knight One was responsible for assembling and maintaining the virtual reality device Knight Two would use to probe Sinclair's mind. Sinclair managed to escape from the machine, causing a feedback that scrambled Knight Two's memory. Knight One pursued Sinclair out into the Zocalo, where he was shot and killed by Sinclair.
