Nildir wasn't the most pleasant of gods. He was one of the harshest, really. Which was why it was such a surprise to the others that he had decided to take someone as sweet and kind as you for his lover. And you didn't look opposed to it... at all, really.

He may have been the god of fire, but you warmed up his heart to possibilities of kindness and love more than anyone had the capabilities to do before. You set the fire of his heart ablaze, and he was going to make sure that you kept it up.
