Krevdes

Krevdes is a term used primarily in speculative fiction and world-building to denote a class of relics, devices, or phenomena that interact with organic fluids. It has no established definition in the real world and is generally treated as a fictional construct or neologism created for storytelling.

In common depictions, Krevdes are artifacts that channel energy, information, or life force through liquids resembling blood. They may be crystalline, biotech, or organic in form. Functions attributed to Krevdes include power generation, healing, memory transmission, or ritual communion. Use is usually contingent on purification rites, compatible substrates, or alignment with specific belief systems, and it can carry risks such as corruption of the user, harm to ecosystems, or social upheaval.

Origin and reception: In-universe origin stories are diverse; some traditions claim Krevdes predate recorded history, others describe them as natural phenomena misinterpreted as artifacts. In meta-textual discussions, Krevdes serves as a storytelling device to explore themes of life manipulation, hubris, and the tension between science and spirituality.

Notes: Because Krevdes is a fictional concept, there is no canonical source or bibliography. It is sometimes used in world-building exercises and fan-created lore as a flexible tool rather than a fixed object.
