They were two sides of the same coin. They were light and dark. They were life and death. They were very different but more alike than one might imagine, by some cruel twist of fate they were in love with each, but they believed the other to hate them.
Life was regal in everything he did. Whenever he bestowed a soul into a creature he did it in the most dramatic way. On the other hand, death was blunter with what he did, whenever he took a soul he simply asked for it to take his hand and gently escorted it to the afterlife.
The first time they saw each other was an accident. Life was bestowing a soul into a newborn child and death was asking for the mother's hand.
