Neverwinter Forest And it comes from the way you speak

The Mother's herald was neither a creature of the night nor a creature of the day. When he was hungry, he would eat, and when he was tired, he would sleep. All this while carrying his mistresses' words deep within his heart. 

But even he could admit the moon was exceptionally beautiful tonight. Atka could feel her calling to him, beckoning. Nature was a beautiful thing, the death that came along with it equally so. Suddenly he felt the urge to kill in her name, though Atka was not one to obey his primal urges...most of the time.

Enveloped by the great orb in the sky as he was, the canid did not notice Alduin's approach. But even when he did, the slow turn of his head showed no fear. What did he have to fear but death? It happened to everyone eventually, except Atka had not fulfilled his life's purpose, so death was not an option. 

"Brother." Was the only word uttered from him as he took in his elder womb-mates dark form, the rippling muscles, curled tail. Of course he knew exactly who Alduin was, his image burned into the man's memory. Looking at him now, the moonlight framed his head, forming a sort of halo. An omen maybe? Curious.
