Legions are a hive-mind species which mostly resides in and around the Entente of Ventemir. They are native to the planet Veritas in the Ventemir Galaxy. In a slightly unorthodox hive-mind hierarchy, Legions are composed of billions of independent individuals which can be thought of as nodes in a network rather than the more common distributed-intelligence approach. This network is the legion rather than the individuals themselves. There are only 1.3 billion extant Legions currently known, a small sum for a species so influential.
Legions are most known for their role in the ancient civilization known as the Triumvirate Civilization. During the existence of the Triumvirate, only three Legions existed. These three, Holo, Auluer, and Legio, ruled the entirety of the Ventemir, Via Sagittaria, Via Lacrimosa, Ouranir, Florescence, and Sheol galaxies. When the Triumvirate collapsed in 201 CE, these three would be fractured into all of them modern Legions which exist today.
While Legions do not have a set biology, they all have general shared characteristics. Within their heads is a large copper wire which can send and receive signals up to one and one half kilometers. These signals have a remarkable density and have since been enhanced through artificial means.
The hivemind itself is made up of billions of individual bodies, each body with the intelligence of the average sapient organism. As a consequence of this, Legions are some of the most intelligent naturally-evolving organisms to ever exist.
Many Legions hook themselves up to cybernetic bodies to interact with other species. They most commonly choose Atlins to imitate. Other common species they emulate are Humans and Ravis. Most of the bodies of the Legions are extensively modified to the point of being unrecognizable to the original bodies. Most are bipedal, however, bodies can have anywhere from two to three hundred limbs depending on need.
