Snow covered and almost barren, Snow Valley is the most influential region on Sarvannia today, though this was not always the case. Originally, the most influential region was Artic Range. This did not change until Arctic Range was suddenly abandoned by the people of Sarvannia. It was at this point that the Devilian rebuilt his kingdom within Snow Valley, right on the banks of the salt water river that flows from Risky Range and along the border of Artic Range, Glacier Rapids.
Glacier Rapids is the only body of salt water that is cold enough to form large chunks of snow and ice called glaciers. These glaciers are either stationary or flow with the torrent waters. Mixed with its deathly cold temperatures, powerful undercurrent, and vicious white water rapids, any attempts to cross it will prove fatal. The only safe place to cross is the short run right after it leaves Risky Range but has not yet reached Pool Mountain, located on the border between Snow Valley and Eastern Prairie. Once the waters reach the shallow pool located at the top of Pool Mountain the smooth yet fast moving waters turn into the violent, deathly-cold rapids that are impossible to navigate or cross.
The Devilian and Devilianta, the unofficial king and queen of Sarvannia, are one of the most influential royal couple on the planet, second only to the Devil and Deviless. This is because their throne is the inheritor of the original Sarvannian throne, the very same throne that to this day holds the rightful title of King and Queen of Sarvannia. It is also the same throne that was abandoned along with Arctic Range, though which was the cause of this abandonment and which was merely a side effect is uncertain and highly debated.
