In "Sea of Shadows" by Kelley Armstrong, Keepers and Seekers have strict rules regarding their appearance, particularly the length of their hair, which is only allowed to be trimmed to elbow length. Ashyn points out that they should consider themselves fortunate compared to the spirit talkers, who are prohibited from cutting their hair or nails entirely. This highlights a hierarchy of appearances among different roles within the community.

Moria, one of the characters, reflects on the severe restrictions of spirit talkers, noting that their condition includes far worse penalties, such as the loss of eyes, tongue, and even nostrils. While she acknowledges the inconvenience of uncut nails, her concern for the more brutal consequences faced by spirit talkers underscores the harsh realities of their situation. This serves to enrich the narrative by illustrating the sacrifices made by individuals within this world.
