Slithering across the earth's surface, mysterious invisible entities called Daysellers haunt the most wretched humans, feeding on their despair and suffering. They shift from one sorrowful mind to another to explore and consume it, since only the deepest, darkest, and most twisted aspects of humanity's depressing nature provide the most appetizing feast. Daysellers are known to push people over the edge to sweeten their meals, but occasionally, a specific Dayseller takes pity on an unfortunate person it stalks and whispers words of hope to help end the pain.
