Solaris Project

The Solaris Project was a temporal research program conducted in the city-state of Soleanna and headed by the Duke of Soleanna. It forms the basis for the storyline of Sonic the Hedgehog (2006).

The project's primary facility appears to have been Aquatic Base, a high-tech laboratory complex located beneath the waters of Kingdom Valley. Its duration is unspecified,[1] but the game shows that the project ended in disaster some 10 years prior to the main events of the storyline.
