Once a local woman hired as an actress for the mountain horror film, she fled into the dense brambles when the production turned genuinely deadly, her white wedding costume catching on every thorn. The mountain's malevolent influence fused her with the thorny vegetation, transforming her into a living part of Beacon Hill's ecosystem. Now she eternally wanders the course's most treacherous areas, forever seeking others to share her thorny fate.

The Bramble Bride exists as a fusion of human tragedy and living vegetation, with thorny vines growing through her preserved wedding dress and emerging from her pale skin like decorative jewelry. Her touch causes brambles to sprout from the ground and existing thorny plants to grow more aggressively, creating natural hazards that reshape the course layout. The air around her carries the sickly-sweet scent of dying roses mixed with the metallic tang of fresh scratches, while her presence is often announced by the sound of fabric tearing on unseen thorns. Faded spray-paint marks on the brambles around her spell out warnings in multiple hands, suggesting previous encounters with terrified players.

She serves as the mountain's seductive guardian, appearing to lost players as a victim in need of rescue while actually luring them deeper into Beacon Hill's most dangerous bramble patches. Her role in the horror ecosystem is to transform the natural terrain into active threats, making the course itself complicit in the supernatural danger.
