In the world of Black Clover, magic is everything. From social status to survival, the strength of your magic can define your entire life. Arguably, one of the most dangerous groups introduced in the series is the Eye of the Midnight Sun. They are a secret organization that appears as one of the main antagonists in the early arcs of the anime and manga.
They are a group of rogue mages called the Eye of the Midnight Sun, who want revenge against the Clover Kingdom as they feel they’ve been wronged in the past. They are powerful and secretive and intimately intertwined with the history of the kingdom itself. Eye of the Midnight Sun is introduced as a major threat to the Magic Knights and the Clover Kingdom.
Their leader, Licht, is a mysterious individual who leads a group of powerful fighters who possess unique magical abilities. Right under the leader was the Third Eye. The Third Eye in Black Clover consisted of three individuals who were the strongest fighters in the group. Their names were Rhya, Vetto, and Fana. Below the aforementioned three are the remaining members of the group.

Their ultimate goal in Black Clover is to overthrow the kingdom and form a new world where they can live freely, free from the cruelty and discrimination they think they’ve faced. They also work from behind the scenes to gradually shape events, often getting others to act on their behalf, but all the while concealing their ultimate objectives.
Little by little throughout the story, we learn the Eye of the Midnight Sun isn't comprised of typical villains. Many of them are reincarnated elves, a once-peaceful race of magical beings. Many years ago, the elves were decimated in a horrific incident called the Elf Massacre.
They thought the humans of the Clover Kingdom in Black Clover had betrayed them and were killing them out of jealousy and fear of their powerful magic. As a result, the elves, who now inhabit human bodies, are bent on avenging their fallen brethren.

One of the most intriguing characters from Black Clover is the leader of the group, Licht. Initially, because of the limited view we get of him, we see him as just a powerful enemy who carries a deep hatred of humans. But as time goes on, we learn that he’s not really evil. He is driven by grief, betrayal, and the desire to protect his people.
The person we think is Licht for much of the story turns out to be someone else entirely, a man named Patri who looks really similar to Licht. Patri is another reincarnated elf, and he’s the one leading the Eye of the Midnight Sun in their mission of revenge. His journey from hatred to understanding is one of the emotional highlights of the series.
The Clover Kingdom experiences a ton of havoc due to the actions of the Eye of the Midnight Sun. They raid villages, seize the powerful magic stones, and even try to conquer the kingdom by force. They cause some of the most intense fighting in the Black Clover anime, with the Magic Knights trying desperately to keep them at bay. In battle, Asta and Yuno, and the captains of the Magic Knight squads, are faced with their toughest challenges.

One of the biggest turning points in the story is when the elves were reincarnated. Patri collected all the required magic stones and placed them in the Sephirot. As a result, all the elves that were sealed were reincarnated, including Licht. He is much calmer and wiser than Patri and helps bring peace between the elves and humans. Thanks to the main characters, the elves start to realize that not all of humanity is responsible for their suffering.
Turns out that the massacre was orchestrated by a demon named Zagred. He had spent a long time planting seeds of animosity in humans and made everything look like their fault. When the elves were reincarnated, Licht and Lumiere, the first Wizard King, fought alongside each other to protect the world of Black Clover. Ultimately, with the help of the Magic Knights, Zagred is defeated.
Their Aftermath in Black Clover
This marks the end of the Eye of the Midnight Sun as an enemy group. And instead of animosity from the humans, this became the start of the healing process between the two races. Even after the group is no longer active, the impact of the Eye of the Midnight Sun can still be felt in the story.

Their actions changed the way people in the Clover Kingdom see magic, power, and history. And the war they initiated forced the kingdom to reckon with its past and strive for a better future. It also made Asta and his friends in Black Clover better as people and as fighters.
And in a sense, the Eye of the Midnight Sun is an emblem of pain, vengeance, and the desire for peace. Their story shows us that those we think of as enemies might have been wronged all along. It also shows how understanding and forgiveness can break the cycle of hate.
Conclusion
The Eye of the Midnight Sun is one of the major aspects of the story in Black Clover. Their backstory is tied to the core characters, giving their story a more authentic quality and not simply identifying them as another evil organization. They serve as a reminder that in every struggle, there is a story, and behind every fight, there is a reason.
