Monarchs or Sovereigns are calamity monsters that decided to invade Earth as their new home ground.
The Absolute Being (God) in another world, split the forces of Light and the Dark into eight pieces each. These became the eight Rulers and eight Monarchs.
Their purposes set by the Absolute Being, the Monarchs wanted to destroy the Universe while the Rulers fought against them to maintain it. The Rulers, tired of the never ending war begged the Absolute Being to aid them and destroy the Monarchs, so that peace could finally happen. The Absolute Being refused, and soon the Rulers discovered that the gruesome war between the Monarchs and the Rulers were merely for amusement.
Tired and filled with grief about the war, seven of the Rulers rebelled against the Absolute Being, all except Ashborn, who remained loyal. However, Ashborn's efforts were for naught and soon the seven Rulers succeeded in destroying the Absolute Being.
Ashborn, angered by the seven Rulers who killed the Absolute Being, joined the side of the Monarchs and became the Shadow Monarch.
When the Monarchs betrayed Ashborn and left him weakened and vulnerable, the Rulers came in with their armies. However, instead of killing Ashborn, they begged him, the Greatest Fragment of Brilliant Light, for forgiveness. However, Ashborn, whose wish for death was ignored by the Rulers, simply left. Because Ashborn had killed Baran, one of the Monarchs in the battle who betrayed Ashborn, the scales of war tipped to the side of the Rulers. Six of the remaining Monarchs hid in the gap between dimensions, biding their time and rebuilding their forces. The Monarchs, still bent on destroying the Universe, had set their sights on another planet, Earth. Another war had ensued. and during it Earth had been destroyed 7 times. Hoping to save Earth, who had no Mana and was destroyed in the war 7 times, the Rulers injected Gates into Earth to increase its Mana to survive the coming 8th war.
