Orionis

Orionis is the name of the solar system that is home to most characters here.

There aren't too many planets known yet but so far it goes Sun ( Cosmo Rigel ) > Autonoe > Eris > Agroria > Kerberos. The reason not many planets are known is because they all seem to have life on them and we don't want them to think we are attacking them when we land to explore. That could be detrimental for us all. Especally after the Kerberos incient.
