Most Boreal Dwarves (Enutanik) live in the remote southern island of Naasitaq, where they share the rocky tundra and snow-covered forests with migratory pale elves and the coast-hugging ships of aumaua.
Like their northern cousins, Enutanik share an instinctive love of exploration.
Boreal dwarves are somewhat common in the Vailian Republics but seldom encountered in the Dyrwood.
