About
Lumagine is a mind-control fabric that allows one to change the appearance of his clothes by thinking. Fanchon Quills adapted the technology to make the explorers' shadow badges, which lets them temporarily modify the look of their clothes; the user can tell that the badge is activated by a passion fruit smell. The Lumagine shadow badges are used by Cruz and the other explorers in various situations in the Explorer Academy series.
