The endless war between Light and Darkness

Flashback

'At the dawn of time, when light and darkness was all that existed, the Absolute being split the light to create the Rulers and split the darkness to create the Monarchs. As the Monarchs were born to destroy the world and the Rulers born to protect it, it wasn't long before they engaged in a devastating war with each other.

Eons later, when the Absolute Being was ousted and murdered, the Rulers used tools containing fragments of his power to hunt down the Monarchs and were able to capture the Monarch Legia alive, tipping the tide of the war in their favor and giving them a solid shot towards victory.

Realizing this, the Shadow Monarch Ashborn reached out to the Monarchs and offered his help. As they had no other viable choice, the Monarchs reluctantly accepted him as their new ally.

Ashborn is betrayed by the Monarchs

Unfortunately for Ashborn, even though he managed to stabilize the power balance and keep the war going, his overwhelming powers earned him great fear from both sides and eventually led two Monarchs, Beast and Baran, to betray him and ambush him with their armies.

Although Ashborn easily defeated both Monarchs and killed Baran in retaliation for his treachery, his shadow army was nearly annihilated.

Antares allows Ashborn to rejoin his forces

Deciding to seek revenge against the Beast Monarch, Ashborn went into hiding to revive his army, allowing the Rulers to finally win the war and forcing the Monarchs to escape to the cracks between worlds.
