Finally finished a minor Reference Sheet for these two <3 I needed one with all the short-stories, ideas, and art I've been doing with @sarndipityart .
The Zin-Ashari clothing was inspired both by in-game Kaldorei and ancient Greek garments, just based on how they perceived Zin-Ashari in some cinematics and artwork, it looks like the inspiration is of that era, or ancient Asian architect as well.
They are very much so my 'Ody/pen' ship I'd say, loving each other apart continents for thousands of years and finally get reunited in the end.
To go into some lore for these two; they were married maybe a few months before the Sundering took place, and were both middle-class in regards to hierarchy in Zin-Ashari times. Nassiandor was going to school, learning Mage-Things and Viannorie was a herbalist that worked in the Royal Gardens. They most likely met, due to his father being an architect in the City, and when they joined as mates they made matching pendants of the moon.
Pregnant, Vianne had moved outside the City to her family in Hyjal for support when the Rebellion began, and thus the Sundering as well. She never found Nassiandor, and believed him dead - the stress of such a belief unfortunately swiftly ended the life she was carrying.
Years later under the Tutelage of Druidism, she was given the chance to train two young Kaldorei [Alyraei and Elyssaelora] who's Highborne parents had abandoned them. They were highly capable of Arcane magic which was forbidden now by their people; but Vianne could only see Nassiandor in their similar palettes and eyes, adopting them swiftly without question as she aided them to understand druidism; and in secret, the Arcane that had meant the world to her late husband.
With her children growing to be exceptional Balance-Druids, Vianne's life seemed fulfilled in most ways, but she still missed her counterpart, even all of these years later. She'd always waited for some sign that he was alive, but one never came -- until Bel'Ameth. Settling down with the rest of their people, Viannorie was introduced to some of the previously outcasted Demon Hunters, Fallen Dark Rangers, and other unwanted Kaldorei.
And there he was, different, but the same. I'm still fleshing it all out, but the Night Elves have so much lore to go through and try to timeline it, yeesh.
