"Solaris Phase 1" is the theme for the first phase battle against Solaris in Sonic the Hedgehog (2006), and to a certain extent acts as his theme song. The song is unique among the game's soundtrack as it is entirely in Latin. The lyrics of the song are written in the manner of a religious hymn that gives off a grave warning against bringing about a divine being. The translated lyrics also point out that everything in life must be in service to the truth.
