He was laughing with her as he spread his wings and lifted her from the ground, twirling her. Nyx gasped and clutched his neck. Kalona tightened his arms around her. "Trust me, Goddess. I would never let you fall."

From the Sun and from the Moon, two winged brothers are born: golden Erebus, playmate and friend, and mysterious Kalona, Warrior and lover, companions of the Goddess Nyx.

And at the edges of the Earth, a Darkness is stirring, waiting for its chance, for the doorway in through a heart that it knows will welcome it…
