The tattoo was first seen on the arm of the Wayward Vagabond, who refused to dwell on or explain the tattoo, saying it brought back "unpleasant memories". This may be a reference to his experiences on the Battlefield, or could be something unrelated. Spades Slick is the only character shown to find a use for them so far, when he discovers a barcode scanner in [[Lord English|LFile:EnglishO.gifrd English]]'s vault. When he scans his arm, it opens a hatch to a base not unlike those which the Exiles encountered in 2422. The tattoo resembles the unprototyped Battlefield.
