The Lucif Family was a family known for it's failed contribution to Project 'Ma'. Despite not making much diffrence in the Project, they became known as the ancestral family to the Lucifenian Royal Family.
During the BT era, Vey Lucif married Marina and lived with her in Magic Kingdom Levianta. At some point, Marina was selected for Project 'Ma' and was impregnated with a pair of twins. Before the twins were born however, Vey kidnapped his wife from the royal insitute and removed the children from her womb, leaving her dead.
Vey raised the twins in secret and through them, the linage was kept going and survived in name with invidviduals as Lali Lucif. Before the EC 200s, the linage had led to the d'Autriche Family which eventually became the Lucifenian Royal Family through Lucifenia I. However the blood linage died off when the last descendant, Riliane Lucifen d'Autriche, died without any children.
