The ritual mask of the Eski-na is a haunting visage, crafted from weathered bone and reinforced with frost-kissed wood, its surface etched with intricate carvings that tell the stories of ancestors long past. Icy blue pigments, made from crushed minerals and frozen berries, streak across the mask in jagged patterns, mimicking the relentless winds of the tundra. Long strands of woven fur and sinew dangle from its edges, swaying like ghostly tendrils in the bitter cold.
