When Dew’s mother, an elf, went into the old forest and joined with the king of stags, she broke an ancient taboo of her people - but in doing so she greatly pleased the goddess Nissa, The Dancer, who favors the deer and wild green spaces, and those who become one with nature.
Thus, Nissa sang her sweet blessing while the two were coupled.
Perhaps as a boon from Eru, and against all likelihood, Nessa’s song allowed this mismatched union to beget a living child!
A little girl was born; both elf and deer, immortal yet transient, and of the wild.
Named Mídhmir by her mother, the Dewdrop Jewel, she possessed Nessa’s love for dance and speed, and ran on spry hooves through the forest with the deer, unable to be contained.
When she grew mature, and her curious mind began to think thoughts far beyond the concerns of wild animals, Dew followed her mother afar to experience a great elven city.
There, though she quaked at the lifeless walls and tall towers blocking the sky, she felt compelled to enter the temple of Yavanna, the queen of the Earth and all its plants and animals - to whom her deer half made Dew a subject.
But - she also drew the goddess' curiosity.
So, that evening, as the moon rose, the elder goddess herself visited her temple.
There, she saw what her younger sister, Nessa, had sung to life, leaping and dancing in the moonlight.
Yavanna smiled, and the light of her smile gave the wild deer girl a sense of comfort and belonging, even in the city of the stern and judging elves.
Dew felt she could cease running, use her mind to meet the sentience of others, and focus, for the first time in her life. She wished to read, and to make things with her hands...
She was small, frail, and afraid, but in return for the gift of Yavanna’s smile, Dew pledged herself as a champion to the nature goddess; moved by her devotion, Yavanna accepted.
She called down her husband, Aulë, the god of craftsmen and material things, and creator of Dwarfkind.
Together, they opened their divine mouths and sang a duet for wild little Mídhmir. Calling upon the harmony of Eru, the song was heard through all the world’s natural places and the craft halls alike, at the same time.
Wild things calmed and listened, while craftsmen and women were inspired, elves and dwarves and men; some, spurred to create great works, as the music rang in their ears.
There in the temple, kneeling within the divine harmony, the young deer-girl’s shape became fluid, formless, blended into the blinding moonlight.
When it coalesced, she stood changed. She looked like an elf! Was she an elf now?
No. Her dual essence remained, and she found herself able to choose at will between the form of an elf, and her old form, a faun.
Keen of both mind and craft, and fleet of foot among the trees, she was crowned that night as Yavanna’s champion, an agent of protection against those who would do harm to nature.
As a faun, she would now be called Mídhróumir, the Wild Dewdrop.
When walking as an elf among her upright kin, they called her Taurarashiel, or Arashiel for short, for she was the forests’ deer-daughter:
a product of the Valar’s blessing thrice over, and an eternal figure of grace and natural harmony that all of elfkind would revere.
