ésor

ësor is a fictional concept used in speculative fiction and world-building to denote a medium that records, stores, and transmits sensory experiences and memories. In narratives, an ësor can take the form of a physical artifact, a field of energy, or an ambient phenomenon that participants interact with to review or share past events. The term is typically described as a constructed word, often stylized with the Albanian letter ë to convey a particular phonetic or aesthetic.

In fiction, ësor is associated with themes of memory, identity, and time. Its properties can include selective playback, subjectivity of recollections, and the potential for manipulation or misremembering. Authors may present different rules for how the ësor operates, sometimes tying its function to cultural practices, ritual use, or technological development within a imagined society.

While not part of any official language or science, ësor has become a recognizable device in worldbuilding circles and fan-maintained glossaries. It serves as a narrative tool to explore how communities interpret memory, how experience becomes shared knowledge, and how the boundary between reality and recollection can blur.
