veloihin

Veloihin is a fictional species featured in the science fiction novel "The Expanse" series by James S. A. Corey. They are an ancient, non-humanoid alien race that existed millions of years before humanity's rise. The Veloihin are characterized by their immense biological complexity and their creation of the protomolecule, a sophisticated nanotechnology that forms the basis of their technology and, consequently, much of the plot in "The Expanse."

The Veloihin are not depicted directly in the narrative but are understood through the remnants of their civilization and the effects of their technology. Their history is largely unknown, but it is implied they were a highly advanced species that faced extinction or a significant decline, leaving behind the protomolecule as a means of propagation or transformation. The protomolecule's primary function appears to be the manipulation of matter and life at a fundamental level, capable of converting organic matter into alien structures and even creating new life forms.

The Veloihin's motives and ultimate fate remain a central mystery. Their existence is primarily revealed through the protomolecule's interactions with human and other alien life. The discovery and subsequent misuse of protomolecule technology by various factions in "The Expanse" lead to widespread conflict and existential threats, highlighting the profound impact of this long-lost species on the present-day galaxy. Their legacy continues to shape the destiny of the colonized solar system.
