Holoska (Earth-2605)

Holoska is a small country that appears in Sonic Unleashed. It is covered in eternal snow, and is home to several icehouse villages located on the northern ice cap of the Earth, and thus is the coldest place on the planet. Sonic Hedgehog and Chip visited Holoska during their quest to restore the Chaos Emerald and the continent following the awakening of Dark Gaia.
