drennde

Drennde is a fictional term used in speculative fiction and worldbuilding to describe a diffuse ambient energy or field that permeates a setting. It is not part of real-world physics, and there is no single agreed-upon definition. In many depictions, drennde interacts with both inorganic and organic matter and can accumulate in natural formations, crystals, or landscapes, sometimes influencing local phenomena.

The concept's use varies across works and settings. It originated in modern worldbuilding practices and has appeared in novels, role-playing games, and online fiction. Some in-world explanations tie drennde to ancient rituals, sentient landscapes, or primordial forces, while others treat it as a material resource that can be harvested or harnessed. Because different authors establish different rules, the properties and behavior of drennde are setting-dependent rather than canonical.

Phenomena and applications associated with drennde also differ by setting. In some stories, drennde is described as a low-energy field that can enhance perception, slow decay, or enable resonance-based technologies. In others, it is something researchers seek to map with instruments or to channel through conduits. Environmental and biological effects are likewise varied, ranging from mood or sensory changes in living beings to weather-like fluctuations. As a flexible device in worldbuilding, drennde helps justify supernatural abilities, advanced technology, or ecological relationships within fictional worlds.
