The term "crusader" in literature is multifaceted, often evoking both historical military figures and bold, virtuous heroes. In many narratives, it designates a literal fighter from the medieval campaigns, as seen when characters are described as having donned crusader garb for protection or to signify their martial purpose ([1], [2]). At the same time, authors frequently employ the label metaphorically to exalt qualities such as courage and unyielding determination—for instance, characters are celebrated for their "fighting crusader" spirit or even referred to as crusaders in contexts far removed from historical battles ([3], [4]). In some works, the term imbues an almost mythic aura, linking modern or even ironic portrayals with the storied past, whether through allusions to a noble lineage or as an emblem of unwavering moral resolve ([5], [6]). Moreover, literary uses of "crusader" extend into inventive descriptive passages that associate its historical gravitas with the everyday quest for honor and justice, reminding readers of its enduring power as an archetype of the heroic quest ([7], [8]).
