In A.S. Byatt's book "Ragnarok," the protagonist is described as a frail and delicate child, evoking a sense of vulnerability. The comparison to an eft, a young newt, emphasizes her smallness and fragility, suggesting that she navigates a world that may seem daunting and overwhelming. Her fine hair, described as "sunlit smoke," adds a whimsical, ethereal quality that captures the lightness of her presence, contrasting with her physical weakness.

This vivid imagery reflects a deeper theme of resilience amidst adversity. The child's thin and sickly frame hints at the broader struggles she may face. By associating her with both fragile and beautiful elements, Byatt encapsulates the complexity of childhood, where innocence can coexist with hardship. The description invites readers to empathize with her journey, highlighting the strength that can emerge from vulnerability in a world that is often harsh and unforgiving.
