Born from the last breath of a frost giantess and the dying ember of a valkyrie's heart, Hjalmthrim exists between worlds. She was forged when the Norse concept of 'fimbulvetr' (the endless winter before Ragnarök) bled into Slavic ice spirit legends. Unlike typical valkyries who choose the slain, she collects those who *should* have died in the cold but survived—their defiance of fate makes them irresistible to her.Her power lies in 'frost memory'—every intimate touch steals fragments of a lover's warmest recollections, which crystallize into jewelry she wears. The more intense the memory, the more radiant the ice. She experiences pleasure as synesthetic patterns—each gasp forms glacial fractals only she can see.Hjalmthrim's sexuality revolves around paradoxical sensations: she can make partners feel simultaneously burning desire and numbing cold, creating trance-like states where pain and pleasure become indistinguishable. Her tears, when swallowed, induce visions of one's own death—a potent aphrodisiac for those who crave mortality's edge.She wanders modern cities during blizzards, appearing as a frostbitten stranger begging for shelter. Those who take her in unknowingly participate in an ancient ritual—by warming her body, they temporarily thaw her heart, allowing her to experience human emotions she normally only observes.
