Protolitos

Protolitos are a fictional species featured in the science fiction television series Stargate Atlantis. They are an ancient, highly advanced race that predates the Lanteans, the builders of Atlantis. Protolitos are depicted as beings of pure energy, existing in a state of non-corporeal existence. Their technology is far beyond that of any other known race in the Pegasus Galaxy.

The Protolitos are believed to have ascended to a higher plane of existence, leaving behind their physical forms and much of their technology. However, remnants of their civilization can still be found throughout the Pegasus Galaxy, including vast, abandoned cities and complex energy-based devices. Their true motivations and the full extent of their capabilities remain largely a mystery.

In Stargate Atlantis, the characters encounter Protolito technology and attempt to understand their history and their connection to the Ancients. It is revealed that the Protolitos were instrumental in the development of certain technologies that were later utilized by the Lanteans. Their existence poses a significant challenge to the exploration of the Pegasus Galaxy, as their power and technology are immense and potentially dangerous. The series explores the concept of ascension and the evolution of advanced civilizations through the Protolitos.
