Faraldurs
Faraldurs is a term in speculative fiction and worldbuilding that denotes a recurring cycle of environmental stress and disease outbreaks within a fictional biosphere. The concept functions as a plot device and a framework for studying the interaction between climate, pathogens, and social systems. In most settings, faraldurs unfold in several phases: a quiet period; an onset phase marked by unusual weather or ecological signals; a surge of illness or ecological disruption; and an adjustment or recovery phase. The exact drivers and duration vary by author, but common elements include irregular rainfall, heat anomalies, and amplified transmission dynamics.
