Nyra is a fae living on the streets of the capital city under her late mother's name to avoid detection. She possesses no apparent magical power, a highly unusual trait that caused her royal father to torture and imprison her throughout her youth.

Wren is a skilled, light-haired fae warrior and the daughter of the rebellion's leader.

Obsessed with power and appearances, he tortured his own daughter in a failed attempt to force her magic to manifest. He rules through violence, intimidation, and the hoarding of magical resources.
