Gyre is a planet located in the Altair system and is one of the furthest colonies from Earth at 16.7 light-years away from Sol.


Gyre was colonized in the 22nd century by the newly established Interplanetary Strategic Alliance, and was found to have a surprisingly oxygen rich, breathable atmosphere, eliminating most of the terraforming process. Gyre is smaller and colder than Vekta, largely ocean, and with millions of tiny islands dotting the surface. It is likely that it may be a holiday destination for the Earth's and Vekta's civilians. By the 2300s, Gyre's native population may be in either hundreds of millions or billions.

The colony could be under threat from the Helghast, and if it was invaded by them, it would take weeks for the ISA or UCN to assist and Gyre would fall to the Helghast in a matter of hours like Vekta did, likely having a weaker ISA presence than their neighbor. However, Scolar Visari is more interested in the planet Vekta as it was the home that the UCN and ISA forced the Helghast people from.

There is another planet that may be even further away from Earth than Gyre is all together called Zeronus, but its location is unknown.

As of 2390, Gyre was in the middle of a labor crisis in which millions of Helghast labor unions working in the industrial sectors staged protests for better working conditions, and accusing factory owners for criminal negligence. The crisis subsequently turned into a planet-wide revolt after the accused factory owners were acquitted and provoking disaffected Helghast to taking control of several major city districts and government buildings. Gyre's military proved itself too weak to quell the unrest and forcing the government to negotiate with the Helghast Workers Union Party to peacefully end the bloodshed.

Subsequently, the Aldridge government was forced to step down after a vote of no confidence from opposition parties. New elections were held for a new government in which the Workers Union Party soon came into power. Although the Workers Union Party promised to implement labor reforms, they ultimately failed to live up to its promises and instituted a state of repression, which spurred both Helghast and Vektan demonstrators, working together in a rare moment of solidarity, in condemning the government.[1]
