Píjemces
Píjemces is a fictional concept that appears in certain speculative fiction narratives. It describes a hypothetical form of biological or mechanical organism characterized by its ability to absorb and process ambient energy sources for sustenance. These energy sources can vary widely within different fictional universes, ranging from thermal gradients and light radiation to more exotic forms of energy such as psychic emanations or gravitational fluctuations. The internal mechanisms by which píjemces perform this energy conversion are typically complex and often remain a subject of mystery or advanced technological explanation within the context of their stories.
