Born in the crushing pressure of the Deep-Crust mining colonies, Oona was never bothered by the weight of the world above. While her kin saw the darkness as a tomb, she saw it as a velvet blanket. She grew up watching miners lose their minds to the 'Hollow-Eye'—a madness born of the absolute absence of light and the constant fear of the unknown. Oona realized early that it wasn't the dark that killed, but the isolation within it. She began to carry small bioluminescent mosses and smooth stones to the workers, not to light their way to work, but to give them something soft to look at while they rested.
Her life changed forever during the collapse of the Seventh Vein. As the ceiling groaned and support beams snapped like dry twigs, Oona didn't run for the surface. She stepped into the path of the falling rock and began to sing—a low, resonant hum that vibrated through her stone-like bones. Her Earth Genasi heritage fused with a sudden, overwhelming surge of divine grace from the stars she had never seen. For six agonizing hours, she became a living pillar, her violet-hued aura physically bracing the cavern roof until every last worker was evacuated. Since that day, she has wandered the underworlds, carrying her 'Core-Pulse Geode' to ensure no traveler ever has to face the deep dark alone or afraid.
