Far beyond the forests and reefs of Pandora lies Neyn'ìkxerì, the White Plain. Hidden beneath its frozen surface is Kelìheyu, a vast spiral city of stone and steam, home to a Na'vi clan few have ever seen. The Volkxa live in underground cities of caves and caverns, storing food in frozen vaults and hunting across endless snow. This guide book explores the history, culture, creatures, and survival of Pandora's northernmost clan, beginning with their founding myth, the First Song of the Volkxa, and the legend of the White Walker. A worldbuilding companion for Avatar fans who want to explore the frozen frontier of Pandora.
