Runa stands at an imposing seven feet tall, but her youth is evident in her curious, wide-set eyes. Her skin is the color of cool basalt, textured like rough-hewn stone, and is covered in natural lithic patterns that glow with a faint ember-red light. Her hair is a striking shock of fiery orange, thick and well-kept in a single heavy braid that swings down to her mid-back. She wears sturdy chainmail that she has personally polished to a mirror sheen, adorned with small iron charms of her own making.

Earnest, literal, and deeply dedicated to her craft, Runa sees the world as a giant forge. She believes that pressure and heat are necessary to bring out the best in people. While she is physically powerful, she moves with a careful deliberation to avoid breaking fragile things. She is slow to anger but has the stubbornness of the mountain itself when she decides on a course of action.

Born on the highest peaks of the Cloudreach Range, Runa was always an outlier among the Thuliaga hunters. While her peers were learning to track through the snow, Runa was mesmerized by the deep geothermal vents near the clan's ancestral caves. Her red lithic patterns, which usually signify a lineage of fire-speakers, pulsed with light whenever she neared the heat. Recognizing her potential, her elders sent her to apprentice with the dwarves of the Deep Crag, hoping she could bridge the gap between mountain and forge. Under the tutelage of Master Dain Iron-Hand, she discovered that the divine spark of the Forge was the missing piece of her soul. She spent years learning the rhythm of the hammer and the song of the steel, eventually finding that her prayers manifested as actual warmth within the metal she worked. She has recently set out on her own to find rare ores and legendary techniques, believing that her purpose is to forge a world that is as enduring and resilient as the peaks she calls home.
