"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.
The song primarily plays during the Solaris first phase boss battle, although bars to the song were heard in the scene where Elise is crying and thus forced to release Iblis upon Mephiles' murder of Sonic as well as him proceeding to reform into Solaris and causing a time wave to spread through Soleanna.
Connections to game
- E schi no ne voles voli sanctus a // E schi no ne voles pres e frui meloda (Do not wish forth the willed holy name's schism // Do not welcome the schism's grave melody) - A reference to how Solaris had been split apart into Mephiles the Dark and Iblis during the disastrous Solaris Project, and how Mephiles and Iblis upon fusing back together planned to destroy time itself. Might also reference Mephiles' seduction of Silver into initially attempting to murder Sonic in a misguided attempt to stop Iblis's creation.
- Väde no vi ero a // Sende no vi ero a (No Force will be there to be seen // So send a new force that will be) - a reference to how Solaris plans to devour all of time itself, and foreshadowing how Solaris's flame has to be destroyed to undo the events of the game's story.
- Vive sanctus ici e si se sus veri (Live is a holy power if it lits the truth) - A reference to the fact that Solaris was originally a sentient flame before the doomed Solaris Project.
