Nerieae (Neer-ee-ah)

Nerieae was once a powerful fairy living in The Moors, a magical forest realm bordering a human kingdom in the Feywilds. Her father was the king of all fairies living in The Moors and answerable only to the Queen of the Seelie court. He died when she a young girl, leaving her heartbroken. Not long after, she met and fell in love with a human peasant boy named Stefan Moorshard, who fell into the Feywilds through a random Fey Crossing. However, seeing the power that the Fey possessed, his own love for her was eventually overshadowed by his ambition. As they both got older the two grew apart, him being drawn to King Henry Westshire and her taking her rightful place and becoming protector of The Moors.
A year or so later, King Henry tried to expand his borders and attacked The Moors. Nerieae and Henry engaged in battle, with Nerieae mortally wounding the human king and forcing his armies to retreat. As he laid dying, Henry declared that whoever kills Nerieae will be named his successor and be pledged to marry his daughter, Princess Leila Westshire.
Stefan, still ambitious and wanting power above all else, visited Nerieae in The Moors. He drugged her, but was unable to bring himself to kill her (perhaps remembering the deep love he once had for her). Instead, he severed her wings using iron and presented them to the king as proof of her “death”.
Devastated by Stefan’s betrayal, she turned The Moors into a dark kingdom and transformed a raven named Diaval to serve her. After seeing what she had done to her beloved kingdom, she left The Moors and vowed never to return.
After leaving she found a new home on the continent of Faerun in the world of Toril, not far from the area known as the Sword Coast. Eventually, she met and took refuge with a group of good-aligned dragons, who taught her their magic since her fairy magic was no where near as strong without her wings. After some time, she was able to use this magic to regrow her wings at will and in whatever form she chose. The treated her as one of their own and the dragonborn that lived nearby began to teach her the ways of the druid. So influential was she that she became known in the area as the mother of dragons, especially among the younger wyrmlings that were hatched in recent years.
Despite all this, she is still in constant struggle with her two sides--one, the gentle fairy that live in unity with nature as a druid, the other a vengeful and wrathful “dragon queen” that will stop at nothing to protect those she loves (even if it costs others around her their lives).
