The Southern Tundra is the southern-most continent of the planet Mobius, constantly featuring frozen temperatures and snow storms.
For a while it acted as the home to the self-exiled Overlander Nate Morgan and his friend Eddy the Yeti, though after his house was destroyed in a battle between Sonic, Tails and Ixis Naugus resulting in Eddy's death, Nate returned with the two heroes to Knothole. (StH: #64, #65, #66) It is also a frozen waste land, something like what Antarctica is to us, the coldest continent on Mobius.
Sonic briefly revisited this area again while trying to undo the effects of a time-altering beam with Nate's Super Emerald strapped to his back. At that point, he was in the form of Polar Sonic. (StH: #71)
Some time later, Sonic returned to the Southern Tundra to place a rose on Eddy's grave, only to be attacked by the recently escaped Ixis Naugus. Sonic defeated Naugus however, once again imprisoning him in the Zone of Silence before returning to Knothole. (SSS: #15)
Most recently, the Xorda dispatched the Quantum Dial in an attempt to destroy the Mobian solar system. Nearly every living Mobian (and one deceased Mobian) rushed to the southern tundra to stop the dial. The battle ended when Sonic used his speed to implode the dial, warping him to the planet Thoraxia, causing everyone to believe he had died. (StH: #125)
