Teenagers who run away from home to live in the wilderness may become feral. As they become more and more feral, they gain some supernatural powers (a la Peter Pan - ability to fly, things they imagine come true - possibly quite powerful), but at the expense of their humanity and ability to speak, comprehend complex subjects, etc. Maybe they have a leader: the most feral of them all.
A regression into a fantasy childlike state.
Far to the north amidst the endless ice-flows it is rumored that a dwarven Walrus Totem clan exists. These rumors have been unsubstantiated to date, unless the dwarven sage Glurt Goblinguts is to be believed. He claims to once having encountered a troupe of huge dwarves, each standing a beard’s length higher than the tallest known dwarf. These dwarven “giants”, their hairy chins crusted with frozen shards of ice and dirt, hauled gargantuan yellowed horns or tusks upon their wide shoulders, and their helms, likewise, sported massive, down-ward pointing tusk-horns. Glurt Goblinguts later speculated that the impressive size of these dwarves was most likely due to their arctic diets, almost exclusively fat-based.
