A Fate Written in Wings and Shadow

In this world, there are three ruling powers:
the Dark Fey, the Light Fey, and humans.
The Dark Fey bear wings as black as midnight.
The Light Fey shimmer with wings of pearlescent light.

And humans-wingless-stand between them.
Once, there was peace.

It was upheld by a rare species born of all three-
creatures with gray wings and human hearts.
They were called Tribrids, and they were the thread that bound the realms together.

Until one night, they were hunted to extinction.
All except one.

Her name is Nyx.
