Lucifer smiles as he watched the horse making his way slowly through the portal it interested him that the horse did so willing without fear. As soon as he walked in he used his powers to remove the portal temporarily only to turn back in time to see an arrow flying at the black foal and he used his powers to make the arrow miss the horse. Soon however they were in the throne room of his father and he knew it was about to be a fight so he readied himself. 

"How dare you bring that evil creature into my kingdom you know that the darker the animal the more evil it is" God said looking at his son angrily. Before hearing Mary. 

Lucifer looked at the foal interacting with Mary before turning his head toward his father "I've looked at hundreds of thousands of horses to be my war horse and none of them got my interest. But now I have found the horse I am going to raise to be my horse because I don't care about his color father. I love him already and he loves me. Isn't it you that always said all creatures and people are able to love if given the chance? Well I am doing exactly that" he said feeling the foal headbutt him once more. Slowly Lucifer petted the foal's head lightly and smiled at it "His name is Nightrunner."
