The Daughter of Oberon: Normally, female children of the seelie court are referred to as "Daughters of Titania". However, she has grown to have the nickname "Daughter of Oberon" instead and has thus taken it on as a title. She does not seem to acknowledge that she is, perhaps, the only one known by such. Instead, she acts as if both daughters of Oberon and sons of Titania are completely normal.

 At first, this normally masked figure may be mistaken for a simple wood elf. Being observed, though, a sort of aura radiates from her- the effectiveness depending largely on one's will and race. Full blooded, weak willed humans attracted to the female gender are the most affected and thus the most avoided. Even without seeing her face such mortals may find themselves feeling the urge to be closer to the elf.  For those resistant to the charms of others the elf strikes feelings of uneasiness often rather than attraction.
 For those well acquainted with the nymph race her fey blood hailing from the beautiful creatures may be guessed at.

 A rosy, tanned shade colours her skin; the lack of paler spots revealing the fact the "tan" was natural (common for wood elves). Like her skin her hair is normally a pink touched shade but in a far lighter tone than the tan of her body. Foliage is tangled from the head into her long hair down to the tips, various colored flowers, leafs and other gifts from the forest collecting within the peach strands. The length of her wild mane that touched down to her knees shows she didn't often cut her hair... if ever. Despite this, her elven ears may be the first thing spotted through her hair as they're at a sharper point and length than normally natural.
 Soft pink pieces of jewelry with tiny gems set in them decorate the length of each of her ears.

 If examined it could be found that her hair is silky despite the foliage seemingly tangled in it and her skin is smooth despite obviously trekking through forests often (judging by the amount of dirt usually seen on her skin and clothing). Her body is nicely curved, perhaps too nicely as there doesn't appear to be a single thing really wrong with this woman's appearance. Even those initially attracted to her grow to find the consistent oddities of perfection somewhat unsettling. Unsurprisingly her voice is as attractive as some may consider her appearance.

 Carrying very little on her body her manner of dress is just as light with a favor towards somewhat darker colors. From the amount of skin she shows and the signs of forest on her it's safe to assume she harbors somewhat of a dislike for being constrained in too much cloth. The woman may have a strange natural beauty but she had little dress-sense. The clothing she does wear she moves awkwardly in.

 Strange designs decorate the visible parts of her elven body, likely some kind of paint as these designs never look the same twice. No matter the design the Sylvan nature in them is always apparent. Crossing her path multiple times may allow one to realize that the colour of her hair can change at times. The shade remains the same throughout a singular interaction only changing after a time when the fey like creature has been alone. She smells of the forest, usually a shifting smell that could be of a certain flower one day but a herb the next.

 Noticed when there is no light parts of the elf shimmer and sparkle giving her the look of someone who got caught in a wrestling match with a faerie dragon. Her neck always sports a pendent with the image of a white stag on it.

 When her mask is removed the reason for the piece becomes clear. Both of her eyes are filled with an inky blackness which most people aren't very fond of looking at. Very rarely does she make eye-contact as the pits of black can inspire a creeping, drawn in sensation partly due to being set upon her sculpted face. Seeing "Nii" without her mask causes the elven's gifted beauty to become otherworldly and vaguely threatening.

"Come away, O elf child!
To the waters and the wild
With a faery, hand in hand,
For the world's more full of weeping
Than you can understand.

For She comes, the elf child!
To the waters and the wild
With a faery, hand in hand,
From a world more full of weeping
Than She can understand."
