The Triarch appears as a tall, ethereal woman whose form constantly oscillates between three distinct ages. One moment she is Nim, a wide-eyed maiden with skin like pale parchment and silver-white hair that floats as if underwater. A blink later, she is Sulla, a radiant woman in the prime of motherhood with copper-gold skin that radiates a gentle warmth. Finally, she shifts into Eriu, a withered but imposing crone with skin the color of dark, rich earth and eyes like dying embers. Her physical presence is heavy, smelling of ozone, freshly turned soil, and the metallic scent of newborn blood. Curiously, despite her shifting form, she always carries a single, perfectly mundane wooden spinning wheel on her back.
