Solaris

Solaris  is the god of time, light, and fire. No one knows where it came from. Some believed it to be one of the Seven Ixis Master Works, while others believe it always existed.

Experimentation in Soleanna
Ten years ago, Solaris was a small white flame in the research labs of Soleanna. The people of Soleanna worshipped Solaris as their patron deity and held an annual ceremony to ask for its loving light and not its destructive fire. The Duke of Soleanna and his researchers, however, were experimenting with Solaris in an attempt to harness its time-warping powers. They ended up splitting the creature into two halves- Mephiles, the smokey spirit that consisted of power and intelligence and was trapped within a device called the Sceptor of Darkness by Shadow the Hedgehog, and Iblis the spirit that consisted of Solaris's fiery power and destructive nature and was sealed within the Duke's daugher, Princess Elise, through the use of a Chaos Emerald, which killed the Duke in the process.

Rebirth and End
Years later, Mephiles was released from the Sceptor of Darkness. With the power of the Chaos Emeralds, Mephiles rejoined Iblis and Solaris was reborn. Solaris began to devour time. Its eyes opened across time and space and began to consume all as localized black holes. An alliance between heroes and villains managed to recover the Chaos Emeralds, revive Sonic the Hedgehog, who was killed by Mephiles, and see to Solaris's defeat. Sonic and Elise were sent back to the days before Solaris was experimented on. Elise took the tiny white flame and snuffed it out, thus ensuring the disastrous split never occurred. (CSE)
