Cosmic Gate

Cosmic Gates represent a classification of precursor transportation infrastructure whose operational principles remain only partially understood by contemporary science. On Terra, these structures were positioned at both the northern and southern extremities of the planet's major continents. Talos-II, by contrast, possesses only one confirmed Cosmic Gate, located at its northern polar region.

When discovered by humanity, both Cosmic Gates on Terra were found in states of severe damage. Through immense effort, researchers managed to restore the less-damaged northern structure, commonly called the "Sami Cosmic Gate". Exploration revealed it led to what was initially termed "subspace," though this has since been determined not to be a true Ætherside. After countless attempts and sacrifices, following the reactivation of the precursor celestial calculation and measurement device known as the "Celestial Fulcrum" within Terra's home star system, humanity finally identified the Cosmic Gate's paired counterpart. This breakthrough allowed the first steps onto the soil of Talos-II.

During the colonization of Talos-II, humanity exercised deliberate caution by refraining from any modifications to the planet's Cosmic Gate. This prudent approach meant no additional Cosmic Gates were discovered in the process. However, scientists across the Civilization Band widely maintain that other Cosmic Gates must exist within Talos-II's star system.

This vital passage between Terra and Talos-II remained operational for five years until the outbreak of the First Aggeloi War, when humanity lost access to the Talos-II Cosmic Gate. Today, the Talos-II Cosmic Gate lies shrouded beneath the Aurora of Talos-II, beyond the reach of human activity. Its current condition, along with the status of Terra on the other side, has become inaccessible to human knowledge.
