Alandaritids
Alandaritids are a hypothetical group of extraterrestrial beings proposed by science fiction author Alistair Reynolds in his novel "Revelation Space." The term itself does not refer to a scientifically recognized classification but rather a concept within a fictional universe. Within the narrative, Alandaritids are depicted as an ancient, highly advanced, and almost incomprehensible civilization. They are characterized by their immense age and their capacity to manipulate spacetime on a grand scale, evidenced by their construction of the enigmatic Inhibitors. The Alandaritids are not a species in the traditional sense, with observable biological forms, but rather are alluded to as a diffuse, perhaps even post-biological, entity that has long since transcended conventional existence. Their motivations and ultimate goals remain largely mysterious, serving as a narrative device to introduce a sense of cosmic dread and the vastness of time and technological possibility. Their existence is inferred through the remnants of their technology and their profound impact on the galaxy's history as described in Reynolds' works.
