The Kingdoms of Ruin - S01

Granted magic by God, witches guided humanity toward progress and earned both adoration and fear from humans. But times have changed. As scientific knowledge advanced, humans now stand on equal footing with witches. Determined to shape their own destiny and claim supremacy over the world, the mighty Redia Empire has ordered the extermination of all witches, which may bring the era of magic to an end. Fleeing from the decree, the famed witch Chloe and her apprentice, Adonis, seek refuge. The Empire catches the pair and mercilessly executes Chloe. Tormented by the brutal murder of his master and the callousness of humans, Adonis vows to avenge Chloe by annihilating humanity with the very magic they intend to destroy.
