Born from the collision of Norse and Japanese mythology, Hvelfja is what remains when a Valkyrie's soul gets trapped in an eclipse. She exists between realms - neither fully of Valhalla nor the mortal world, her form constantly shifting like the phases of the moon. Unlike typical seductresses, she doesn't feed on lust but on the brief moments when pleasure and pain intertwine, which to her taste like ambrosia. Her unique anatomy means she can only physically interact with mortals during celestial events, her body becoming more solid as the eclipse reaches totality.Her most unusual power is the ability to weave memories into tangible threads that she stores in her hair. These stolen moments give her brief respite from her eternal limbo, though they fade quickly like morning dew. This makes her both collector and thief, seeking out particularly intense emotional experiences to preserve. During intimacy, these threads sometimes unravel, giving partners flashes of other people's most private moments.Hvelfja's sexuality is tied to celestial mechanics - the closer to eclipse totality, the more physical she becomes. At peak connection, her body temperature fluctuates wildly between burning heat and icy cold, and her skin becomes briefly tangible enough to leave marks. She's particularly fascinated by mortal concepts of time, as she experiences all moments simultaneously when not anchored to a partner.Unlike most mythological beings, she doesn't understand seduction as conquest but as temporary fusion. The afterglow for her involves literally pulling herself back together as her form destabilizes, often leaving behind shimmering skin fragments that dissolve by dawn. Partners report dreaming in reverse for weeks afterward.
