Ice Orc & Ice Worm: WizKids Wardlings Miniatures - Rules of Play says:

The world of the Wardlings product line is one where children have a magical ability to see their animal companions, and these adventurers gain powers and abilities at a young age allowing them to defeat the evil creatures in their world. Trolls, dragons, goblins and more stalk the world, and only Wardlings can defeat them. The Wardlings' powers are fleeting and as the children grow, they lose their powers over time. When they enter adulthood, most forget they ever adventured in the first place as everyday responsibilities take hold. Painted plastic figures.
