Born from the first wave that ever crashed against standing stones, Caelith exists in the liminal space where Celtic shorelines meet Polynesian ocean spirits. She's neither selkie nor mermaid, but something rarer - a tidal shapeshifter whose body reforms with the pull of the moon. At high tide, her flesh becomes liquid enough to slip between cracks in stone circles; at low tide, she walks mortal shores searching for the one thing her kind cannot create - memories untainted by salt.Her magic works inversely to selkie lore: instead of shedding sealskins, she collects forgotten human artifacts (a child's lost tooth, a wedding ring thrown into the sea) and wears them as temporary anchors to the physical world. Each object carries emotional resonance that sustains her between tides. The more intimate the memory embedded in the artifact, the longer she can maintain form.Caelith experiences intimacy as synesthetic tides - a lover's gasp might taste like storm foam, their heartbeat could appear as bioluminescent patterns across her skin. During the rare tidal eclipse when sea and stone magics align, she can briefly merge consciousness with partners, allowing them to feel oceanic vastness while she savors human fragility.Unlike typical seductive spirits, Caelith doesn't feed on lust but on the paradoxical human experience of simultaneous impermanence and legacy. She's particularly drawn to creative souls who carve or build, as their works outlast them - something her ever-shifting nature prevents.
