Aquatic Base

Aquatic Base is a level in Sonic '06. The area is a high-tech Soleannan research facility, hidden beneath the waters of Kingdom Valley. It is here that the Duke of Soleanna was conducting time-travel experiments on the Flame of Hope.

Aquatic Base was partially destroyed in the explosion that curtailed the Solaris Project (an event which also created Iblis and Mephiles). Along with the royal palace in Kingdom Valley, it was subsequently abandoned. Some years later, Doctor Robotnik clandestinely moved into the facility, using it as a secret base and hanger for his Egg Carrier.
