Maeve gave a few pixies the chance to be truly Fae, thus creating the Aes Sidhe. Aes Sidhe generally resemble their former pixie forms, on a larger scale. They have a pixie's bright coloring but lack the glow of magic. Their wings are longer and thinner, and have a glass-like sheen.

Primrose, like most Aes Sidhe, was once a pixie. She wished to be a part of the Bigger, and pleaded with the Winter Queen to gain her transformation. After asking three times, she was transformed, but it came at the cost of a century of service.

Fortunately, she really enjoys her work!
