So, the power system is like, there are seven noble houses, members of each house can control the main types of energy

Light, electrical, thermal, nuclear, chemical, mechanical, sound

and there are people who can control the companions of this energies, like, the things associated with energy like shadows and darkness for light

The most capable heir among the hoses' heirs is chosen as the crown prince, right to throne is not by blood

Dark mages were in the Light House's responsibility since only Light can conquer the Darkness

House of Light was also sentenced to this because during the founding of the Empire,

Our MMC is Lucio ( take the hint ;)), he comes from a family of Light users.

The day Lucio is chosen as the crown prince,a Dark Mage appears and tells this story:

"Light users wanted to always be the royals because they thought Light users are destined to lead since they are also kind of metaphorical.

Light users took control of the dark mages and made them lose their power, turning them into Shadow knights who have weaker dark powers.

Light users enslaved the Dark Mages"

Since the other houses know how powerful the light house is, they back up Dark Mages.
