The Sia'Nuss are a race of scientists, primarily motivated by the comprehension of the universe in all its aspects. They remain the most mysterious race in the galaxy. The Sia'Nuss have advanced to the very top level of the evolutionary development. They constantly strive to achieve harmony. Their science is extremely advanced, but any further progress is impeded by the small size of the population that survived the Mirk onslaught. The Sia'Nuss are a dying race. The intelligence of each Sia is unique, and thus every individual is extremely important for the entire race. The Sia reject the concept of war, as it is a powerful manifestation of the forces of entropy. On the other hand, they have developed numerous "clean" defense measures against various enemies.

Having asked humans for help, the Sia did not find sincere support and trust. Only the Guardians and Bioses knew right away that Sia'Nuss could become a powerful ally, so they made quick contact. Humans, on the other hand, simply promised to collaborate against the Mirk. Through various developments, from medicine to light torpedoes, the Sia made a sizable contribution to the struggle against the advancing Anti-Element. Their numerous hybrid inventions allowed the Guardians to be more effective in their battle against the Manifestations. However, a lot of plans could never be implemented: after the Last Mirk Wave, which disrupted most of the remaining Highways, contact with the Sia'Nuss was lost. Nothing is currently known about their fate. Nonetheless, the projects they left to humans are viable and will be implemented.

The primary function of Core Pylons is collection and storage of the star's energy, and passing of the quanta to the Light Core as a building resource. The obtained star energy is translated into the power facility of the Core ring for the purpose of its first launch, which requires a colossal starting impulse. The pylons are distributed in large quantities around the Light Core.
