They don't have the concept of family, so everyone is a product of incest, except the founder and the female Lucifer. Coming of age ceremony helps them achieve the final growth stage, but can be only done within the race. Here ML's son helped them achieve the impossible through his power. Lilith was the only female Lucifer but she exhausted her energy giving birth and died ...I think Lilith + Perion (Original Lucifer) = Valcan (1st Lucifer) and Cesare (2nd Lucifer) Lilith + Valcan = Organ/Park Hajin (3rd Lucifer) Lilith + Cesare = Shion/Park Siwoon (4th Lucifer), Veil/Park Sehun (5th Lucifer), Lisent/ML Dad (6th Lucifer)
