Not all Demons are sons and daughters of Demons.
Many Demons are born from various and precise procedures that involve Dark Magic, Summoning Magic, and Demonic Arts.
There are also many that originally were not Demons, but were turned into Demons. Such practices are forbidden in most parts of the world, but Dark Mages capable of performing such Rituals remain in high demand, employed almost exclusively by royalty and nobles of high courts to settle scores, or get revenge.
Such a Ritual was once performed on the Duchess of Caryll, pregnant at the time.
The Duchess had extremely high Magic Affinity, and there were very few who could match her ability to draw power and Mana from Artefacts.
Her child was sure to inherit her strength, had she not been cursed by one of the Duke's older concubines.
The baby was born, and discarded right away, due to its black tail, nascent wings, and endless appetite that caused more than one midwife to weaken, faint, and eventually die.
