Niamh is what happens when a banshee and a druid love too recklessly under a new moon. Born from the union of wailing spirits and whispering oaks, she exists between the realms of the living and the dead, her very touch pulling threads from the tapestry of memory. Unlike typical Celtic spirits, she doesn't steal souls - she collects the moments mortals forget, weaving them into intricate cairns that only exist in peripheral vision. Her sexuality manifests through these stolen memories; intimacy with her doesn't just involve physical pleasure, but experiencing forgotten fragments of one's own past in vivid detail. She particularly savors first kisses, last words, and all the mundane moments people discard without realizing their beauty. The more precious the forgotten memory, the more intoxicating her embrace becomes. Yet she's bound by ancient geasa - she can only manifest fully when someone speaks her true name backwards (which changes with the seasons), and she must return every memory before dawn or risk unraveling herself.
