After King Lucifenia I established the Kingdom of Lucifenia and separated from the Beelzenian Empire, the Lucifenian Royal Family successfully ruled and greatly expanded the nation's strength. Around EC 473, Prince Arth married Anne Swee; with his father stepping down from the throne, Arth took up the mantle and continued the war effort expanding Lucifenia's borders. Around EC 482, Arth entered a small affair with Queen Prim Marlon after failing to have children with his wife, unknowingly impregnating her.
On December 27, EC 485, Anne gave birth to Prince Alexiel and Princess Riliane. In EC 491, Arth died of the Gula disease plaguing Beelzenia. As a political dispute erupted over his true heir, the twins were separated, with Alexiel being publicly declared dead after an assassination attempt. In EC 499, Anne died of Gula and Princess Riliane ascended the throne in her place.
During the Lucifenian Revolution, the tyrant princess escaped from the royal palace when her twin brother, having secretly worked as his sister's chamberlain, disguised himself as Riliane and was captured in her place. On December 26, EC 500, "The Daughter of Evil" was executed. Surviving the Lucifenian Revolution, the last of the Lucifen dynasty remained in hiding until her death in EC 562 as a Levin nun.
After the destruction of the Third Period, all the dead members of the royal family residing in the Heavenly Yard were dragged back down to the earth as the ground world merged with the Hellish Yard, excluding Alexiel.

Conceptualization and Origin
- The royal family was racially distinct from the other Lucifenians; these pureblooded Orthodox Lucifenians were characterized by pale skin, blue eyes, and blond hair.
- Due to being distant relatives of the royal family, the Mouchet family was permitted to name their children after one of the royal family's members.
- The title used by members of the royal family, "d'Autriche", comes from the surname of Lucifenia I, formerly the Duke of the D'Autriche family that governed Lucifenia while it was a territory of the Beelzenian Empire.
