The Empire of Ice is an Adventure Pack level in in the console versions of Skylanders: Spyro's Adventure, available only in the Empire of Ice Adventure Pack. Slam Bam comes with this Adventure pack.
According to a Story Scroll, stories are still built around the greatest catapult ever built: The Leveler, which has defended the warm valley of Vindlevale for centuries. Without the Leveler, there is little chance that Vindlevale could defend itself against the cold loving armies of the Ice Ogres and Snowclops that dwell nearby.
Story
Haldor, the Great Northern Wizard, sought the Skylander to help him save his village of Vindlevale from the Ice Ogres, who have turned the village into an icy wasteland by blocking out the sun using a giant wall they built. Once at Vindlevale, Haldor explained to the Skylander about the Ice Ogres ruling over his village and turning it into a frozen wasteland. He tasked the Skylander to collect parts to The Leveler, a catapult that will be used to destroy the giant wall that keeps the village in eternal winter. Once The Leveler has been assembled, the Skylander used the catapult to destroy the giant wall, saving Vindlevale from the endless winter and returning the warm sun to the area.

In the console version, you can not get to the level unless you have a Water Skylander or a Skylander who has the ability to fly or go on water - unless you select the level from the Chapter Select menu of the pause menu.
In the console version, the Enemy Goal is set higher than the number of actual enemies in the stage, requiring the use of a Skylander that can increase this total, such as Sonic Boom's Hatchlings.
