In literature, "vestige" is frequently used to evoke the lingering trace of something that has faded or vanished. Authors employ the word both in tangible and abstract contexts—illustrating, for example, the absence of creative spark in lost worlds ([1]) or the disappearance of historical structures ([2], [3]). It also captures the sense of something once vibrant now reduced to a mere echo, as seen in depictions of lost truth or human qualities ([4], [5]). Moreover, in narrative moments of disappearance or decay, such as a character’s drained expression or an unseen destination ([6], [7]), "vestige" powerfully underscores the gradual relinquishment of what once was.
